DD15, DD30, DD60 Compact Inline Desiccant Dryers

Model(s): DD15, DD30, DD60

Always place a bulk separator, particulate and coalescing filter upstream of the desiccant dryer. Desiccant coated with oil will not absorb oil and will render it useless. A check valve should also be installed at the dryer inlet to maximize the life of the desiccant. (Note: that desiccant must be ordered separately.)

As wet air enters through the inlet, the air travels down through a bed of desiccant which absorbs the water vapor and aerosols. The silica gel desiccant beads will reduce the humidity down to a -40°F ( -40°C) pressure dew point. After the moisture has been removed, the dry air passes through a sintered bronze filter element (eliminating desiccant dust downstream), up the tube and out the outlet port. As the desiccant becomes saturated with moisture, the dew point will begin to rise. This is evident when the green silica gel desiccant beads in the onboard sight glass change to orange, indicating the need for desiccant replacement. Simply remove the flange and bowl and replace with new desiccant.
