Warm, moist compressed air (1) entering the dryer is cooled in the air-to-air heat exchanger (2) where it is pre-cooled by the cold, dried air leaving the dryer. This reduces the heat load on the refrigeration system and ads to the dryer's
efficiency. The air is cooled to the dewpoint temperature in the lower part of the heat exchanger (2) by a refrigerant circuit with a thermal storage medium (3). The condensate formed by the cooling action is separated from the compressed air by the multi-stage, stainless steel, maintenance-free separator system (4). The automatic condensate drain reliably removes condensate without wasting valuable
compressed air. The dried air leaving the dryer is reheated in the upper part of the heat exchanger (2) before exiting. This helps eliminate pipe sweating downstream. |
