As much as 80 to 90% of the electrical energy used by an air compressor is converted to heat. A properly designed heat recovery unit can recover 50 to 90% of this heat for heating air or water.
The overall. efficiency of a typical compressed air system can be as low as 10-15%. For example, to. operate a 1 hp air motor at 100 psig, approximately 7-8 hp of electrical power is supplied. to the air compressor. To calculate the cost of compressed air in your facility, use the formula shown below: Cost ($) =.
