Letting compression heat go to waste
Costs as much as
a first class
At atmospheric pressure, air contains a base level of energy, which is increased during the compression process. Up to 94% of the electrical energy is converted into compression heat. Without energy recovery, this heat is lost into the atmosphere via the cooling system and radiation.
The amount of energy that can be recovered depends on the size of the compressor and the running hours. Typical recoveries are between 50% and 94%. As nearly 70% of all industrial processes include the use of hot water or steam, energy recovery units can reduce both fuel and maintenance costs of alternative equipment.
