Working Principle

The industrial air dryer machine for a compressor is based on the principle of freezing and dehumidification, which forcedly cools down the compressed air containing a large amount of saturated water vapor. While maintaining the pressure of the compressed air basically unchanged, the temperature of the compressed air is reduced, so that a large amount of water vapor in the compressed air is reduced.

It is in a supersaturated state, and in the saturated state, the water vapor condenses into liquid water droplets, entraining dust, through the steam-water separator, the moisture and dust are separated and discharged through the automatic drain, so as to achieve the purpose of freezing and dehumidification.

Core Advantages

«       Perfect heat exchange performance, saving cooling power consumption

Sollant industrial air dryer for compressor, the pre-cooling and evaporation system adopts aluminum plate-fin heat exchanger design, the heat exchange performance is far greater than the conventional shell and tube heat exchanger, and the limit temperature difference between the air inlet and outlet can reach 2℃, reducing the required cooling capacity can better ensure the treatment effect and reduce the energy consumption of the refrigeration dryer.

«       Large heat exchange area, small airflow gap

The aluminum plate-fin heat exchanger is constructed by overlapping multiple corrugated fins and baffles. The fin spacing is very small and the number of layers is large, so the heat exchange area is large. The heat exchange has a compact structure, but the fins airflow gap between is very small.

«       Stainless steel wire mesh filter separation

Most of the water separators of aluminum plate-fin heat exchangers use stainless steel wire mesh filtering and separation methods, which have the advantages of simple structure and high separation of steam and water.

«       Efficient refrigeration accessories

Danfoss thermal expansion and hot gas bypass valve can achieve precise operation and durability of the refrigeration system. The expansion valve controls the injection of liquid refrigerant into the evaporator, protecting the compressor from the influence of liquid refrigerant.

«       Perfect control and protection device

• Realize condenser fan control through temperature and pressure sensing
• Sensor failure alarm
• Pressure dew point is a too high or too low indication
• Refrigerant high-temperature protection can stop the compressor when the exhaust temperature is too high
• Automatic start and stop of evaporator ice block
