Introduction: AD series of dry air generators for transformers, reactors and other large power equipment in the installation and maintenance to provide dew point up to -55 ℃ ~ -70 ℃ high purity dry air, can replace the traditional hot oil cycle, add nitrogen, vacuum Such as drying methods, and more efficient, economical, safe and environmentally friendly. The use of AD series of dry air generator for electrical equipment installation, maintenance, can not be affected by changes in external climatic conditions, especially overnight operations, just sealed around the flange, filled with dry air to 0.02 ~ 0.03Mpa can, the transformer , Reactors and other electrical equipment will not be damp. Greatly reducing the workload, to shorten the duration, improve the quality of installation and maintenance results. Features: AD series of dry air generators mainly by the gas source system, freeze drying system, adsorption drying system, air filtration system and PLC intelligent electrical control system and other components. Air source system consists of dust filter, screw air compressor, radiator (air-cooled), gas-water separator and filter components, the output clean oil-free gas. Freeze-drying system components: The device is mainly imported full-closed high-temperature compression refrigeration unit, stable and reliable performance, you can get more cooling capacity. The system is equipped with imported fully enclosed compressor unit, air heat exchanger, evaporator, gas-water separator and fine filter; refrigeration process R22 refrigerant first by the closed high-temperature compression refrigeration compressor, cooler, desiccant, electromagnetic Valve, and finally through the evaporator back to the refrigeration compressor, in the evaporator internal 0-5 ℃ low temperature environment. Electrical control: the main control of the electrical part of the use of Schneider Electric; machine electrical performance is stable, safe and reliable. Technical indicators: Working pressure: 0.7 ~ 0.8MPa Finished product dew point: -55 ℃ ~ -70 ℃ Gas use pressure: ≤ 0.2MPa Dust particles: ≤ 0.01μm Refrigerant: R22 Compressor (kw): 2.6 Total power (kw): 58 Power: three phase ~ 380V 50Hz Air supply diameter: 58 mm Dimensions: Long: 3150 mm Width: 2200 mm High: 2800 mm Equipment weight: 3780 kg
