Turn a Rotary Screw Compressor into an Energy Source

Industrial compressed air users looking for new ways to combat rising energy prices often overlook a significant resource in their plant: energy recovery from air compressors. Kaeser Compressors’ new whitepaper, “Turning Air Compressors into an Energy Source,” explains heat recovery savings from rotary screw compressors.

The heat generated by compressed air systems can be a very good source of energy savings. In fact, 100% of the energy used by an industrial air compressor is converted into heat. 96% of this heat can be recovered (the balance remains in the compressed air or is radiates from the compressor into the immediate surroundings). Too often that heat is lost to the ambient environment through the compressor cooling system. The good news is that nearly all this thermal energy can be recovered and put to useful work to significantly lower a facility’s energy costs.

Authored by industry experts Werner Rauer and Michael Camber, the whitepaper discusses how the heat rejected by rotary screw compressors can be harnessed for a variety of plant uses to yield sustainable energy savings. It also gives key tips on when heat recovery may or may not be an efficient way to save money.

“Heat recovery can be used in a wide range of applications for anything from simple space heating to heating process fluids,” explained whitepaper co-author Michael Camber.

“The trick is to take a close look at your current system to see where the heat recovery potential is,” added co-author Werner Rauer. “If you look for it, you will find it.”

For more technical resources for the compressed air industry, Kaeser's  website has additional whitepapers, including “Effects of Rapid System Pressurization on Air Treatment Components,” “Piston Versus Rotary Screw Compressors,” and “CAGI Data Sheets: An Apples to Apples Comparison.”
