PCR

When warm, dry air is critical to the manufacturing process, air dryers are often installed as part of the plant’s compressed air system. One of the most common designs is a non-cycling direct expansion refigerated air-dryer. API Heat Transfer has developed the PCR, or pre-cooler, cooler, reheater, designed specifically to meet the needs of the refrigerated air dryer market.

The PCR is a compact multi-section all-aluminum heat exchanger featuring a brazed bar & plate design. The PCR pre-cools the incoming air using the cold air exiting the refrigerant section. It then final cools the air in the refrigerant section at which point the air stream enters a separation chamber to allow the condensed moisture to fall out. Since the air is reheated in the regeneration section, the final humidity remains below 25%.
