Heatless Adsorption Type Dryer

Product Description

Heatless Adsorption Type Dryer

Heatless type Dryer takes advantage of the natural phenomenon of desiccant to establish equilibrium with their surroundings. In this type, wet Air (fluid) is cycled automatically between two desiccant towers, one adsorbing the moisture from the wet fluid, while the other being regenerated. The wet fluid enters one tower, passes through the desiccant bed where the saturated moisture is adsorbed. A small portion of the dried air at ambient temperature and pressure is passed through the desiccant bed in the second tower for regeneration and is purged to atmosphere. At preset interval, the towers changeover automatically and the cycle continues giving out a regular supply of super dry Air having dew points up to (-) 70C to (-) 80C (At atm. pressure).

Dew point is the measure of moisture content in air. It is the temperature at which moisture content present in the air, starts condensing. Lower the dew point, more dry is the air. Air of (-) 40C Dew Point means no moisture would condense unless temperature of the compressed air is reduced less than (-) 40C. Lower the Dew Point, higher would be the operating cost of Air Dryer. Hence proper selection of Dew point is very important for economical operation of the unit.
