DL Series 40-5400 SCFM
Heatless Desiccant Air Dryers

FS-Curtis DL desiccant dryers are available with three application specific control systems. No matter what your application, there’s a control system just right for your needs. FS-Curtis DL heatless desiccant dryers deliver consistent outlet pressure dew points to -100˚F. By combining the proven benefits of desiccant drying technology with the industry leading design, FSCurtis’ DL dryers provide the most reliable compressed air drying system for various applications.

Benefits & Features:
  • Up-flow drying which allows water and heavy contaminants to drop out of the air stream
  • Premium grade desiccant beads enhance surface area, requires minimum purge air, and have high crush strength
  • ASME and CRN certified pressure vessels
  • Optional pre-mounted filtration package increases lifetime of desiccant and avoids system contamination
  • Precision switch valves automatically shift to low pressure side of the circuit to control process flow

Standard Controller Models: DLS40, DLS60, DLS90, DLS115, DLS165, DLS260, DLS370, DLS450, DLS590, DLS750, DLS930, DLS1130, DLS1350, DLS1550, DLS2100, DLS3000, DLS4100, DLS5400
