Legendary DHA Series and
CDA Series Heat-Les™ Dryers

(60-1,600 scfm)


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
