Hankison HPD Series dryers will produce the design dew point while operating continuously at maximum rated flow (100% duty cycle) at CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 psig.
Standard HPD Series (Heated Blower Purge) Desiccant Compressed Air Dryers: -4°F to -40°F Pressure Dew Points

Designed for applications that were previously forced to accept a 40°F pressure dew point when simple protection against seasonal freezing is the issue. 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 Free-Air (FA) Supercharger option package.
