Heatless Refrigerated Air Dryers

Heatless air dryers are pressure swing adsorbers designed to retain the heat of adsorption within the desiccant beds during the drying process. The stored heat of adsorption is consumed during the regeneration process to remove moisture from the desiccant to provide continuous service.Heatless desiccant air dryers use a desiccant in twin towers – one for drying, and the other for regeneration. Wet compressed air enters the drying tower and passes over the desiccant which adsorbs it and exits as dry air (dew point between –40 and –100° F).
