The cold dryer is a refrigerated dryer, and its working principle is based on the working principle of the refrigeration cycle, which absorbs heat in the evaporator through the refrigerant (compressed air releases heat). Cooling the compressed air. After the compressed air is cooled, due to the same pressure and different saturated humidity at different temperatures, liquid condensate will be precipitated, which will be automatically removed by the steam trap.

• Heat exchanger and air-cooled condenser are independently produced, using hydrophilic aluminum foil, with high heat exchange efficiency;
• Without basic installation, it can be installed under reasonable ambient temperature;
• The external rotor fan is adopted, with large air volume and long service life;
• Refrigeration components and control components are all made of international high-quality brands to improve service life;
• Adopt a new fully enclosed refrigeration compressor, with long life, low noise, reliable performance and high energy efficiency;

The regeneration method of the heatless regenerative dryer is to desorb the moisture in the adsorbent by releasing pressure, so as to achieve the purpose of regeneration of the adsorbent. The source and dew point temperature can reach -20℃~-40℃. The disadvantage is that the waste of regeneration gas source is large.

• Reasonable tower structure and control procedures to ensure the impact position and contact time of compressed air and desiccant;
• The adsorbent adopts national standard high-purity alumina, molecular sieve, and vacuum negative pressure filling method, which is not easy to pulverize and has a long service life;
  3. Adopt the adsorption tank with the pressure vessel certificate, the safety performance is guaranteed;
• The heater has high strength performance, high voltage resistance, electric shock resistance, and good heating insulation;
• Using intelligent controller, real-time display of operating parameters, high precision, better system stability, easy to operate;

The main function of the air storage tank is that the compressed air from the air compressor cannot be put into production immediately. It needs to be temporarily stored in a gas tank. The main functions of the air tank are buffering, cooling, water removal and oil removal. When the air passes through the gas storage tank, the high-speed airflow hits the wall of the gas storage tank to make it converge, rapidly reducing the temperature in the gas storage tank, liquefying a large amount of water vapor, and removing a large amount of water and oil.

• It is mainly used for gas buffering, and at the same time, it plays the role of stabilizing the system pressure
• Avoid frequent loading and unloading of the air compressor and remove most of the liquid water
• The gas storage tank is generally composed of parts and components such as cylinder, head, flange, nozzle, sealing element and support
• It is also equipped with accessories such as safety valves, pressure gauges, and drain valves to complete the functions of different production processes.

The compressed air filter, also known as the water separation filter, is mainly used to filter and separate the water vapor, oil droplets and dust and other impurities in the compressed air, to ensure the cleanliness of the compressed air, and to improve the working efficiency and service life of the air source components.

• The piston-type filter element is sealed with the housing to prevent unfiltered gas from bypassing the filter
• Anti-corrosion filter element, stainless steel core to enhance structural performance, low airflow resistance, seam welding to improve strength
• The new “matrix mixed fiber” medium has a large effective surface area, improves the filtration rate and ensures high efficiency;
• Large open area to minimize pressure drop
