HHL Series Heatless Desiccant Air Dryer

Introduction
Heatless desiccant air dryer uses to identical vessel filled with desiccant. As wet air flows through one vessel, a portion of dry discharged air is diverted through the second vessel at close to atmospheric pressure, reactivating its desiccant. The moisture-laden purge air is vented to atmosphere. Some time later, air flow through the vessel is reversed.
