DHP Series 300-3200 SCFM
Heated Purge Desiccant Air Dryers

FS-Curtis’ externally heated purge desiccant dryers offer consistent dew point performance and are equipped with our advanced purge booster. DHP Series dryers consume less dried compressed air volume for regeneration purpose by the use of a low-watt density heater. Reduce air loss to align supply-side equipment with demand-side requirements to optimize your air system.

Benefits & Features:
  • Low-watt density heater saves energy and prevents premature desiccant aging
  • Premium grade desiccant beads enhance surface area and have high crush strength
  • NEMA4 rated electrical enclosure
  • Optional pre-mounted filtration package increases lifetime of desiccant and avoids system contamination

HEATED PURGE REGENERATION
Moist, filtered compressed air enters the pressurized on-line desiccant-filled drying Tower 1 through valve (A). Up-flow drying enables the desiccant to strip the air stream of moisture. Clean, dry compressed air exits through valve (E) to feed the air system. Tower 2 (when in regeneration mode) closes valve (B), then depressurizes to atmosphere through muffler (C). Valves (D & G) open and the heater turns on. A portion of dry compressed air (purge air) is diverted before exiting (E) and passes through the heater. Hot dry purge air desorbs the moisture from the desiccant as it flows down through Tower 2 to exit at valve (D). Once desorbed, the heater turns off and cool dry purge air continues to pass until the desiccant bed is cooled. Finally, valve (D) closes and Tower 2 is re-pressurized. At a fixed time interval, valve (B) will open and Tower 2 will be placed on-line to dry the bed and valves (A & D) will close. Operations will switch and Tower 1 will be regenerated.
