Industrial compressed air users looking for ways to combat rising energy prices often overlook an available resource in their plant. A new white paper describing how to achieve heat recovery savings from rotary screw compressors is available for download from Kaeser Compressors Inc., Fredericksburg, Va.

Authored by industry experts Werner Rauer and Michael Camber, "Turning Air Compressors into an Energy Source" discusses how the heat rejected by rotary screw compressors can be harnessed for 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 range of applications, for anything from simple space heating to heating process fluids," says co-author Michael Camber.

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

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