Heatless Type of Compressed Air Dryer takes advantage of the natural phenomenon of desiccant to establish equilibrium with the surroundings. The Air Dryer has the feature that the wet air is cycled automatically between two desiccant towers, one adsorbing the moisture from the wet fluid, while the other being regenerated. The Air Dryer is designed in such a manner that the wet fluid enters one tower, passes through the desiccant bed where the saturated moisture is adsorbed and a small portion of the dried air at ambient temperature and pressure is passed through the desiccant bed in the second tower for regeneration. The Heatless Type of Compressed Air Dryer ensures that 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 - 70 ° C.
