Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Optimisation of Cooling Zone ndash Fans operation at Paint Shop

Paint shop gets the Cowl from BIW Shop (Weld shop) for painting In Paint shop it passes first fromPretreatment stage where oil grease dust amp dirt is removed by hot water spray Next the Cowl bodypasses from Phosphate Station to make it ready for primer coat in ED (Electro- Deposition)

A layer of primer is applies over the surface of cowl by CED process and reaches to the oven for bakingamp drying at defined temperature ie 150degC This oven is horizontally connected with cooling zone wherecowls gets cooled by two axial flow fans ie 22KW amp 30 KWBeforeThe Cooling Zone - Axial flow fans are interlocked with the Pretreatment Stage conveyor as shown belowThe Cooling fans automatically comes into operation as soon as the conveyor starts It is found always inrunning mode once the line gets started Cowl takes almost 2 hrs time to reach the oven fromPretreatment stage

Important ENCON Projects Flux maxiox

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

BenefitsEnergy savingIncrease in illuminationEasy maintenance of lights due to lower heightEnhanced life of lightsLocalized need-based zone-wise lighting control

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

(Partial Load)

Method used to raise the water temperature-Now a modification is made in the system in which the heat of the flue gases are extracted and used to raise the temperature of water used for post wash

The temperature of flue gases when burnt is 275degC and with the help of heat exchanger we recovered the heat And this extracted heat is used to raise the water temperature of post wash to the required level

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

LPG Burners

Before

Method used to raise the water temperature-LPG burner were used to raise the temperature of water to 60degC

Post Wash operation-After the quenching process the metaquench42 oil layers needs to be cleaned from the components To remove this oil layer we perform the post wash operation in which the components are dipped and wash with the spray of warm water which is maintained at the temperature of 60degC

Post Wash Tank

Conservation of electricity through utilization of temperature from heated waste gases to heat water in post wash chamber

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

BenefitsEnergy savingIncrease in illuminationEasy maintenance of lights due to lower heightEnhanced life of lightsLocalized need-based zone-wise lighting control

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Important ENCON Projects Flux maxiox

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

BenefitsEnergy savingIncrease in illuminationEasy maintenance of lights due to lower heightEnhanced life of lightsLocalized need-based zone-wise lighting control

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Important ENCON Projects Flux maxiox

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

BenefitsEnergy savingIncrease in illuminationEasy maintenance of lights due to lower heightEnhanced life of lightsLocalized need-based zone-wise lighting control

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

LPG Burners

Before

Method used to raise the water temperature-LPG burner were used to raise the temperature of water to 60degC

Post Wash operation-After the quenching process the metaquench42 oil layers needs to be cleaned from the components To remove this oil layer we perform the post wash operation in which the components are dipped and wash with the spray of warm water which is maintained at the temperature of 60degC

Post Wash Tank

Conservation of electricity through utilization of temperature from heated waste gases to heat water in post wash chamber

LPG Burners

(Partial Load)

Method used to raise the water temperature-Now a modification is made in the system in which the heat of the flue gases are extracted and used to raise the temperature of water used for post wash

The temperature of flue gases when burnt is 275degC and with the help of heat exchanger we recovered the heat And this extracted heat is used to raise the water temperature of post wash to the required level

Important ENCON Projects Flux maxiox

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

BenefitsEnergy savingIncrease in illuminationEasy maintenance of lights due to lower heightEnhanced life of lightsLocalized need-based zone-wise lighting control

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Important ENCON Projects Flux maxiox

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Principle of workingConversion of para-hydrogen to higher energizedortho-hydrogen through magnetic stimulation iethe application of the proper magnetic field tochange the state of hydrogen molecules whichenhances the energy of atom amp general fuelactivity Hydrocarbon fuel molecules treated withthe magnetic energy of the Flux Maxiox tend tode-cluster creating smaller Particles more radiallypenetrated by oxygen thus leading to completecombustion They become more normalizeddistanced from each other having bigger surfaceavailable for bonding with oxygen In thecombustion chamber increased reactivity ofoxygen is achieved resulting in better oxidation ofthe primary hydrogen elements further oxidationof the carbon element the secondary fuelelement

Before At TML Paint shop we have propane based Ovens and hot water generator equipment There weconsume average of 1500 tons of propane gas every year During ISO 50001 implementation we startedcalculating Ovens efficiency which triggered us to work on increasing its efficiency

After We studied and explored the opportunity in this regard We have seenFlux maxiox from CII amp learned that by using this we can increase theefficiency of paint shop Ovens amp hot water generator equipments So Weimplemented this technology which increased the efficiency of equipmentsubstantially

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

Before In continuation drive of Lighting optimization in offices amp shops we encountered an opportunity in PEshop There lighting fittings were roof ceiling suspended which was covering entire height of the shop Howeverrequired effective height of the lighting was half of the shop height of 8 Mtr It was not only energy wastage alsoinaccessible for maintenance The wiring of the lights was such that the lights in unnecessary areas could not besegregated and switched OFF This led to energy wastage and difficulty in maintenance as well

ENCON Projects Optimisation of Shop Lighting System

After Energy Management cell co-ordinated with PE shop team and conducted a brainstorming session forimproving the shoprsquos lighting system As an outcome of the session it was decided to replace the existinglights with energy-efficient LED tubelights Also reduced effective height of the lights to 5 M which was easilyaccessible zone wise for maintenance and resulted in energy saving

BenefitsEnergy savingIncrease in illuminationEasy maintenance of lights due to lower heightEnhanced life of lightsLocalized need-based zone-wise lighting control

Before-We had conventional lighting in our Line -1 we studied the lux level and found that when the lights were off during day time the lux level drop to 200 Lumen which was far below the required lux level of 400 Lumen so the operators used to keep the lights on in day time also

After-We have Installed light pipes in our main line and also provided transparent sheets in roof at logistics area so that we can increase the lux level to 500 Lumen without switching the lights on during day time since we used light pipes hence there was no increase in shop floor temperature also

LPG Burners

Before

Method used to raise the water temperature-LPG burner were used to raise the temperature of water to 60degC

Post Wash operation-After the quenching process the metaquench42 oil layers needs to be cleaned from the components To remove this oil layer we perform the post wash operation in which the components are dipped and wash with the spray of warm water which is maintained at the temperature of 60degC
