Desiccant compressed air dryer - 80 - 5 000 scfm | DHL series
The DHL series dryers feature a dual tower design that allows for continuous absorption of water from compressed air by utilizing a desiccant bed. Drying is achieved by passing wet compressed air through the desiccant bed of one tower, which absorbs the moisture. The desiccant is then regenerated without the use of heat when a small amount of dry air is diverted from the outlet at near atmospheric pressure, successfully drying the wet bed.
The purge flow rate can be adjusted to suit the desired dew point. The dry air flows counter direction through the wet bed, so it can sweep all the water vapor that was previously absorbed by the desiccant.
