Regenerative heatless desiccant dryer

The simplest gas or Regenerative heatless desiccant dryer is the heatless compressed desiccant dryer. It can reach a dew point of -40°C for compressed air systems and other gas or air dryer applications. The damp compressed air that has been through the pre-filter is received by the assembly of the slide piston. The activated alumina or molecular sieve desiccant bed guides the air into the first chamber, where it ascends. This causes the bed to dry out because of its adsorption effect.
