Atlas Copco-brand compressor coolers, including both after cooler and oil cooler components, are mapped to specific part numbers for models such as GA series units. For an Atlas Copco GA160 compressor, part numbers like 1621411000 for the after cooler and 1621411100 for the oil cooler identify heat exchanger units that respectively lower compressed air temperature and cool lubricating oil to maintain stable operating temperatures.
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.
