Desiccant Compressed Air Dryers

Desiccant compressed air dryers function by drawing water vapor into a porous high-water affinity medium. Often placed down-stream or used as a second stage dryer because desiccant compressed air dryers rely on a relatively unsaturated medium to operate effectively. As a second stage dryer, the water vapor pulled into the machine is lower than at the first stage, allowing for the desiccant dryer to product dew points in the sub-zero temperature range.
