2 Visit our Website: www.kaeser.com Meeting Your Compressed Air Treatment Needs Why do we need compressed air treatment? Because ambient air contains contaminants that are drawn into the compressor. These contaminants are compressed and intensified and find their way into the compressed air system. Contaminants are also introduced into the compressed air stream by the compressor, receiver tank, piping, and other installed components. There are three different forms in which contaminants exist: •• Solids - dirt, dust, pipe scale, compressor wear particles • Liquids/Aerosols - oil and water •...

4 Visit our Website: www.kaeser.com Channeling, when an air stream finds a path through the bed and follows the path instead of flowing evenly throughout the bed, is often a problem with desiccant dryers. Channeling can be avoided by using stainless steel diffusers in the inlet and outlet of the desiccant towers and controlling air velocity through the desiccant bed. Desiccant dryers are either cold regenerative or heat regenerative. In cold regenerative dryers, 15% of dried compressed air is diverted from the air outlet and is used to purge the wet desiccant bed. In heat regenerative...

Kaeser Compressed Air Treatment Guide 7 Drain Traps and Aftercoolers Drain Traps reduce plant operating costs, lower maintenance, and prevent air lines from flooding. They eliminate bleeding expensive compressed air through pet-cocks or manually draining compressed air lines and equipment. A ball valve should precede all drain traps to facilitate routine maintenance without interruption. Demand-Operated Drain Traps automatically discharge moisture and oil-containing condensate from the system. Drain traps should discharge only liquids, not costly compressed air, and do not require a...
