Efficiency and your compressed air installation: Why it is important

3

• Did you know that Energy consumption accounts for up to 70% of the lifecycle cost of a compressed air installation?

• Compressed air accounts for a significant part of total energy costs for industrial manufacturers• Typically 12% but sometimes up to 40%

Compressed air energy savings will therefore have a big impact on your factory’s total energy consumption and CO2 emissions

Reducing your running costs by making your compressor installation more efficient now will benefit you for years to come

Turn compression heat into useful energy with heat recovery

• Without energy recovery, this heat is lost into the atmosphere via the cooling system and radiation.

• Typically, between 70-94% of electrical energy can be recovered from a compressor.

• Recovering heat from compressed air reduces the need for purchasing energy, for example to heat hot water or using exhausted cooling air for space heating.

It is estimated that 90% of all industrial air compressors used in the UK could be equipped with heat recovery systems.

It is this reduction that results in lower operating costs and CO2 emissions, also reducing

your carbon footprint.

Did you know that compressor heat recovery technology could save 1.99% of the total industrial electricity consumption in the UK!This is equivalent to removing the emissions from 913,000 cars per year or recovering the energy required to power 1.544 million households
