Desiccant Air Dryer - CompAir CHD Series

  • Heated Purge Regenerative Desiccant Dryer
  • Flows from 300 to 3200 scfm
  • -40°F/-40°C dew point guaranteed

CHD Series dryers improve air system efficiency by the use of a dedicated heater to improve purge air efficiency, reducing the percentage of dehydrated purge air required to regenerate the off-line desiccant tower.

Venturi assist technology boosts the purge airflow through the tower. Compressed purge air volume is reduced, optimizing energy conservation
ISO 8573.1 Class 2 (-40°F/-40°C) dew point performance is guaranteed.

The standard design delivers ISO 8573.1 dew points between Class 2 and Class 3 automatically. Class 2 (–40°F) dew points protect against freezing during low ambient conditions and Class 3 (–4°F) dew points keep your air system bone dry during the heat of summer.

Applications that require Class 2 (-40°F) dew points year round simply need to select the Energy Management System packaged with venturi assist.
