- Water Pressure: 3-4 kg/cm2(g)
- Water Inlet Temperature: 32°C
Delair Refrigeration Dryers operate at high pressure of up to 40 bar on the method of cooling the air to near freezing point to remove the moisture, and the cold, dry air is reheated by incoming air to approximately 10°C below the incoming compressed air temperature at nominal conditions.
The dryer consists of an air drying unit with a centrifugal cum demister pad condensate separator and a refrigeration circuit. The refrigeration circuit consists mainly of a compressor, a condenser, a receiver, a vapour liquid accumulator with liquid refrigerant and an evaporator. The air drying unit consists of two kinds of heat exchangers: air-to-air heat exchangers and refrigerant-to-air heat exchangers.
THE HEART OF THE SYSTEM IS THE SPECIAL FOAMED-IN, PATENTED HEAT EXCHANGER, WHICH MAKES IT OUTPERFORM OTHER DRYERS.
The function of the air-to-air heat exchanger is to lower the load on the refrigerant system and, secondly, to warm the outgoing cold air pipelines to the required temperature.
The refrigerant-to-air heat exchanger(s) further cools the air to the required temperature, thus condensing the water vapour from the air, which is automatically drained.
