THE RIGHT DESICCANT DRYER FOR YOUR APPLICATION A dry compressed air system is essential to maintain the reliability of production processes and the quality of your end products. Untreated air can cause corrosion in pipe work, premature failure of pneumatic equipment, and product spoilage. Atlas Copco's desiccant dryers produce dry compressed air in a reliable and energy-efficient way while protecting your systems and processes

High reliability Compressed air entering the air net is always 100% saturated. When it cools, the moisture will condense, causing damage to your air system and finished products. Removing moisture from compressed air with a pressure dewpoint as low as -40°C/-40°F , Atlas Copco desiccant dryers eliminate system failures, production downtime and costly repairs. Competitive performance A dewpoint down to -40°C/-40°F together with simple and easy controls guarantee the dryer operates in the best way possible. Good efficiency Properly sized pipes and valves ensure a limited pressure drop....

HOW DOES A DESICCANT DRYER WORK? Wet air passes directly through the desiccant medium which adsorbs the moisture. The desiccant medium has a finite capacity for adsorbing moisture before it must be dried out, or regenerated. To do this, the tower containing saturated desiccant medium is depressurized and the accumulated water is driven off. How this happens depends on the type of desiccant dryer: • Heatless dryers use only compressed air as a purge. • Blower purge dryers use a combination of air from an external blower, heat and minimal compressed air. HEATLESS DESICCANT DRYERS Wet...

HEATED PURGE DESICCANT DRYERS Wet compressed air flows upward through the desiccant which adsorbs the moisture, from bottom to top. The regeneration process 2 Dry air from the outlet of the drying tower is expanded to atmospheric pressure 3 and sent over the heater. The heated air is then sent through the saturated desiccant forcing the adsorbed moisture out, from top to bottom. Cooling After the heating process, the hot tower desiccant is cooled. Cooling is done by expanding dry compressed air from the outlet over the hot reactivated tower, from top to bottom. After regeneration, the...
