DHA Series & CDA Series – Heat-Les Desiccant Air Dryers

Critical applications and hostile environments challenge common industrial dryer designs. DHA Series (-40°F) and CDA Series (-100°F) dryers deliver unrivaled performance and reliability through standard and customized orientations.

Pre-configured dryer packages range from a basic fixed-cycle unit to a high pressure, corrosion-resistant model. Every unit we build incorporates our AMLOC^® energy management system to assure long component life cycles and maximum energy savings.
