Heatless Regenerative Desiccant Air Dryer
Why We Need Compressed Air Dryers
Untreated compressed air contains many contaminants such as water, compressor oil, pipe scale and
contamination from ambient air. All these contaminants cause excessive corrosion, erosion, freezing and
product contamination to all components that come in contact with the untreated compressed air. A
regenerative type dryer system with all recommended filtration will remove these contaminants to harmless
levels. The end result is that instruments that come in contact with the dry compressed air stay clean and do
not corrode, therefore lasting much longer. Products that may come in contact with clean dry compressed
air are virtually unaffected. Therefore rejection rates are reduced.
Purpose & Intended Use
Aircel Regenerative Desiccant Air Dryers can dry compressed air to -100°F PDP (Pressure Dew Point),
Standard Regenerative Desiccant Air Dryers dry compressed air down to -40°F PDP. The compressed air
stream is passed through a desiccant bed, which removes the moisture through the process of adsorption.
Twin towers filled with desiccant alternate between drying and regeneration either based on the Energy
Management System (EMS) control or a fixed time cycle. Aircel manufactures various types of desiccant air/
gas dryers. These dryers offer fail-safe design in the event of power interruption. Air will continue to flow
through the dryer without deadheading; also purge exhaust valves will close preventing loss of air pressure.
The tower operating status lights and the highest quality non-lubricated air/gas inlet valves will ensure
reliable operation for many years to come.
