Atlas Cooler PN 1621183908 1621617008 Intercooler Aftercooler

Atlas Copco cooler assemblies with part numbers 1621183908 and 1621617008 are listed as intercooler and aftercooler heat exchanger units used in ZR series compressors. These coolers serve to remove heat from compressed air between stages and after final compression, helping improve thermal performance and lower moisture content in industrial compressed air 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.
