The simplest way of removing moisture from compressed air is to reduce the temperature. In Refrigerated Air Dryer compressed air is passed through a heat interchanger where cold refrigerant at around 3 Deg C is passed through the other side of the heat interchanger. At this temperature most of the moisture is condensed which is then separated and drained out in moisture separator.
