The Hankison HPD Series Externally Heated Desiccant Air Dryer can maintain the desired dew point (-4°F to -40°F) at maximum rated flow (100% duty cycle) with CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 PSIG.
Previously, applications had to accept a 40°F pressure dew point for seasonal freezing protection. The standard design offers 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, while Class 3 (4°F) dew points keep your air system dry during the summer heat. Applications that require Class 2 (-40°F) dew points year-round can choose the Free-Air (FA) Supercharger option package.
