Desiccant Type Compressed Air Dryer

Twin tower regenerative dryer that works by absorbing moisture on a Sahel desiccant such as Activated Alumina. The two towers operate alternately. Compressed air to be dried is flowing through the desiccant in one tower while the desiccant in the other tower is being reconditioned/ regenerated. The saturated desiccant bed is regenerated by a purge of dry air from the operating tower by a blower purge. Regenerative dryers are often specified to protect instrumentation and central systems, laboratory equipment or moisture sensitive process materials.
