Blower Purge Desiccant Dryer The DPB Series blower purge desiccant dryer process design offers the end user the opportunity to significantly reduce the energy costs associated with achieving a reliable -40°F (-40°C) pressure dew point. This is achieved by eliminating or reducing purge air requirements (compressed air utilized to regenerate desiccant beds) typical of other desiccant dryer designs.
