After cooler
This cools down the compressed air and removes the heat generated by
the compression process. The coolers can be either cooled by ambient air
or with water in water cooled compressors. Selection of either air cooling or
water cooling is made based on individual customer requirements and
location of the installation.
About the part
An aftercooler is a mechanical heat exchanger that cools hot compressed air from a screw compressor and removes condensation. This prevents moisture from building up in the compressor's pipe system and prepares the air for use in air-operated equipment or to enter a dryer. Aftercoolers can be water-cooled or air-cooled and typically come with automatic drainage and a water separator. Air-cooled aftercoolers use ambient air to cool the compressed air. Aftercooler units can lower temperatures to between 5–20°F immediately after the compressed air is released from the compression unit
