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.

Trident Pneumatics is a Heatless desiccant air dryer manufacturer. Regenerative heatless desiccant dryers for compressed air support heatless air and gas dryers for industrial compressed air systems and other different applications.Desiccant air dryers manufacturers and Gas Dryers those are available in both heatless as well as refrigerated types.
