An air-cooled OMNI® compressor rejects heat to the surrounding air and does not need a process water loop, which can simplify installation. A water-cooled OMNI® compressor uses a facility cooling water supply and is a good fit where water is available or ambient heat load is a concern. OMNI® offers both in the 100, 800, and 900 series. The 1000 series is water-cooled.
