Most of the energy consumed by a compressor is converted into heat and then removed via a cooling medium (such as air, water or oil). In an efficient compressed air system, this heat is not lost, but used for other applications within the factory that require heat. Up to 94 percent of the energy used to operate a compressor can be recovered in this way and used to make savings in other areas.
