HPRB SeriesNon-cycling refrigerated air dryers

Hankison HPRB Series dryers are non-cycling refrigerated units for flows from 7 to 1,200 scfm. They hold a consistent 50°F pressure dew point across that range and now run on R513A, a low GWP refrigerant. Maximum inlet pressure is 200 psig on 7 to 50 scfm models and 232 psig on 75 to 1200 scfm models.
