The simplest way of removing moisture from compressed air is to reduce the temperature. In this 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.Simple operation. Low operating cost. Zero Purge Loss PDP of 3 Deg C
