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.
This process involves purging out the moisture from the saturated dessicants with the help of the nearly 15% of the air that
has already been dried.
