Atlas Copco intercooler and aftercooler parts within the 1621315xxx series are listed as tube bundle heat exchanger cores that lower compressed air temperature between stages (intercooler) and after the final compression (aftercooler) in industrial compressor systems.
In industrial compressed air systems, the air compressor cooler functions as a primary thermal regulation component. Proper compressor cooler operation reduces discharge temperature, improves moisture separation, and supports long-term system reliability.
