Refrigerated Air Dryer For Compressor

The working principle of the refrigerated dryer

The refrigeration dryer uses cooling air to condense the moisture of the humid air and then separate it out of the air to obtain drier air. The following is an analysis of the working principle of the refrigeration dryer as follows:

The humid, high-temperature compressed air flows into the precooler (for high-temperature type) to dissipate heat and then flows into the heat exchanger to exchange heat with the cold air discharged from the evaporator, reducing the temperature of the compressed air entering the evaporator.

After the heat exchange, the compressed air flows into the evaporator and exchanges heat with the refrigerant through the heat exchange function of the evaporator. The heat in the compressed air is taken away by the refrigerant. The compressed air is rapidly cooled, and the moisture in the humid air reaches the saturation temperature and quickly condenses. The condensed water is condensed to form water droplets, which are rotated at a high speed through the gas-water separator. The water is separated from the air due to centrifugal force, and the separated water is discharged from the automatic drain valve. The dew point of compressed air pressure after cooling can reach +3~+10℃

The following products are suitable for use at 220V 50HZ, 380V 50Hz voltage, other voltages can be customize:
The compressed air used in the industrial field contains a lot of moisture, which will not only cause product defects, but also shorten the service life of the equipment. Therefore, it is very important to use clean and pure compressed air without water.

The air dryer is one of the necessary equipment to remove the moisture in the compressed air condensed by the compressor in the industrial field.

HHL series compressed air refrigerated dryer armored design, simple and stylish appearance, combined with pipeline air filter, all filters are aluminum alloy die-casting, imported filter element material, EU authority testing, ensuring high efficient filtering. Only need to be connected to the air compressor to use, no need for cumbersome piping and save labor costs.

The refrigerated air dryer adopts aluminum alloy plate heat exchanger, environmentally friendly refrigerant and micro-computer automatic control, which can visually display the dew point temperature of the dryer; it has multiple protections of temperature and pressure. And inside compressor air dryer installed four pieces of high efficiency compressed air filters with an electronic condensate drain, when install and maintain, it is much more convenient.
