Heatless Air Dryer

Heatlees Air Dryer‘ often referred as pressure swing adsorption dryer. Deslccent Dryenand to a lesser extent regenerative dryer . The compressed air is passed through a Coalescing type Pre filter . Here dust particles. water and oil coalesce and removed frorn the stream. Then the air is passed through a pressure vessel with two ‘towers' filled with a media such as activated alumina. molecular sieve or other Desiccant material. This desiccant material attracts the water from the compressed air via adsorption. As the water clings to the desiccant. the desiccant “bed" becomes saturated. The dryer timed to switch towers based on a standard cycle. once this cycle completes some compressed air from the system is used to 'purge" the saturated desiccant bed by simply blowing the water that has adhered to the desiccant off. The duty of the desiccant is to bring the pressure dew point of the compressed air to a level in which the water will no longer condense. A standard dew point that is expected by a Heatless Air Dryer is ~40 °C (-40 °F). required dew point is dependant on application and - 70 °C is required in some applications.
