6.6.1 Aftercooler
The aftercooler is the first and most important step of processing compressed air. It operates according to the principle of a heat exchanger. Air or water can be alternatively used as cooling medium. By reducing the temperature of the compressed air water vapour condensates and is separated from the air via secondary centrifugal collector.
