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
Heat of compression dryers use the heat of the compression
Atlas Copco’s Air Dryers
Atlas Copco’s SD membrane dryers with pre-filters remove moisture, oil and particles from compressed air in the most demanding conditions. The dryers deliver the lowest pressure drop and purge air loss at the highest possible efficiency – saving you time and money. From small spaces to environments with fluctuating ambient temperatures, SD dryers can perform in a wide variety of harsh and critical conditions. Two models are available to offer you the exact air treatment you require.
