Which dryer is most suitable for compressed air, refrigerent or heatless air dryer ?
*A Heatless compressed air dryer ( drier ) is the simplest form of dessicant type gas or air dryer ( drier ) for achieving a dew point of -40°C or better for compressed air systems and other gas and air dryer ( drier ) applications . We are using such drier for a long. One advantage of heatless dryers is that they can be pneumatically controlled, this allows them to be installed into hazardous areas. Dew point is making the difference and -40 deg C or lower, moisture content is almost eliminated. Thats why it is used in instrument air compressor. Heatless type drier 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, white 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 tempe
