Air drying plant

Listing ID #3576865

In Refrigerated Air Dryer plant used. Compressor used in this type of dryer usually of the hermetic type. The dryer work on the principle heat transfer. In the main dryer cooling carry our two stages. First stage air-to air and second stage air –to refrigeration.
Process:
Saturated compressed air enters to air to air heat exchanger, where it is precooled by outgoing cold dry air .Highly effective precooler reduces temperature considerably, and enables to use smaller and economical refrigeration system. Then the precooled, relatively low temperature compressed air enters to air to refrigerant heat exchanger where it is cooled down to 3 degree ( pressure dew point). At this temperature, moisture in vapors from condense to liquid form and separated from compressed air by moisture separator and discharge to drain valve. The cold dry compressed air passes back to air to air heat exchanger. And gain temperature by exchanging heat with incoming out from the dryer id ready to use for instrumentation and process air applications.
