The theory behind operation of Heatless Dryers, is very simple. Chemicais which have the capacity to adsorb moisture on its surface. These adsorbents are used to dry the air. The adsorber are packed into two columns. The Cornpressed air is passed through this Column of packed adsorbent dessjcant. It is obvious that after a certain period or drying (i.e. few hours few minutes) the dessicant looses its capacjty to adsorb more moisture and hence is not capable of drying any more air, in its present Condition. The drying Capacity of the dessicant is restored by the process of regeneration.
