Refrigerated Type Dryers

The Refrigerated Type Dryers, In small Air capacities upto 500 NM3/hr we offer Model-PERD. It's simple and very compact design consisting of a cylindrical heat exchanger with freon tubes. Air flows outside the tubes and gets cooled to 3A C temperature. Moisture condenses out and is drained continuously. The out going air is at 3A C temperature with (+) 3A C Pressure Dew Point which is equivalent to approx (-) 23A C dew point at atmospheric pressure.
For larger Ah capacities, above 500 NM3/hr, we recommend Model -PERDA. It is a skid mounted unit consisting of Air-Freon chiller, Air to Air pre-Cooler and a moisture separator. First air is precooled with outgoing chilled air to around 25A C and then it is cooled in a freon cooler to {+) 3A C temperature. This reduces refrigeration load of the Unit. Outgoing dry air has (+) 3A C Pressure Dew Point and comes out at around 25A C temperature. (+) 3A C Dew Point in Refrigerated Air Dryers corresponds to around (-) 23A C Atmospheric Pressure Dew Point. Still lower Dew Point ls not possible from Refrigerated Dryer as moisture condensed would start freezing on freon tubes if lower dew points are tried.
(-) 23A C is the best possible Dew Point achievable from Refrigerated Air Dryers.
