Steam System Preventative Maintenance

• Annual Steam System Audit / Steam Trap Testing

• Real Time Monitoring• High Pressure steam trap monitoring• Consumption Monitoring• Chiller Plant Monitoring• PRV Monitoring utilizing digital controls

Manual Steam Trap Auditing• Mosto Technologies Inc Audit over 15,000 steam traps annually

• Typically Find a 10% average annual failure rate in each facility

• Without Incentives, typically see a 6 to 12 month payback for testing and replacement of the defective steam traps

Manual System Auditing• Check for steam leaks (wasted energy)

– Steam Traps (Trap Selection)

– Bypass valves

– Safety relief valves

– Vacuum breakers

– Insulation (pipe, valves)

Methods of Loss Detection• Visual

• Infrared Temperature Readings

• Ultrasonic Listening

• Monitoring in Real‐Time on High‐Pressure
