Process Aftercooler

The optional aftercooler cools the moist air returning to the dryer from the drying hopper. The aftercooler can cool the return air from 250ºF to about 150ºF. This maintains the dryer’s efficiency and condenses the unwanted plasticizer from the air stream. The aftercooler requires a cooling water connection (see Figure and page 25).
