A compressed air dryer is a piece of equipment designed to separate water vapor or moisture (de-humidify) from industrial process air. In the typical system, a compressor draws in humid air and compresses it, which raises the air temperature and then cooling the air condensing water vapor out of the unit.

The Refrigeration Dryer consists of anair drying unit with centrifugal cum demister pad condensate separator and a refrigeration circuit. The refrigeration circuit consists mainly of a compressor, a condenser, a receiver, a volume liquid accumulator with liquid refrigerant and an evaporator. The air drying unit consists of two kinds of heat exchangers, one is air toair heat exchanger and second is refrigerant to air heat exchanger.

Untreated compressed air contains water, dirt, oil and other waste particles which will mix together to form unwanted abrasive slurry, this abrasive slurry, generally acidic   in   nature,   will   cause   wear   in   pneumatic   machinery,   valves,   orifice   etc. causing frequent high maintenance breakdowns and costly air leaks. A typical compressed system wastes approximately 35% air due to “leakages” which are mainly caused due to corrosion.

It is thus very essential to install a suitable Air Purification System to meet individual needs.
