How Does it Works

How does it works?

Delair Refrigeration type Dryer
operates on the method of cooling the air to near freezing point to remove the moisture. The cold air is reheated by the incoming air to approximately 10°C below the incoming compressed air temperature at nominal conditions.
The Refrigeration Dryer consists of an air 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 to air heat exchanger and the second is refrigerant to the air heat exchanger.

THE HEART OF THE SYSTEM IS THE PROPRIETARY HEAT EXCHANGER WHICH MAKES IT OUTPERFORM OTHER DRYERS

The function of the air to air heat the exchanger is to lower the load on the refrigerant system and secondly by warming the outgoing cold air pipelines to the required temperature.

The refrigerant-air heat exchanger(s) further cools the air to the required temperature thus condensing the water vapor from the air, which is automatically drained.
