Series AD air dryer device is special for drying the electric equipments and providing the dry air(dew point from -40ºC to -70ºC). When operation and maintenance, electrical equipments, such as transformer and reactor, are quite easy to be moistened. Series AD air dryer supplies dry air to solve this problem, anoxia-asphyxia will never happen to maintenance people. It's more safe, reliable, convenient and economical than by using bottled gas. It is not influenced by bad weather conditions, especially for overnight working, just to fill 0.02-0.03MPa dry air into equipment after sealing all flanges. Electric equipment Oil filling and oil drainage is unnecessary, which can shorten working period and improve maintenance effect. During oil filtration, it can fill dry air into oil equipment block and oil to improve oil insulation and decrease the moisture.
The system is mainly composed of the screw compressor, air cooler, gas storage tank,adsorbing dryer and air filter. System working automatically, reliable and easy operation.
Screw air compressor pump air into the gas storage tank, most of the moisture is compressed to the liquid water, and discharge out from the gas storage tank, so the air is first time drying. Then the air goes into the air cooler, which can condense the moisture into water again, so the air is second time drying. Then The air goes into the adsorbing dryer, which can adsorb the left moisture from air, so the air is third time drying. Finally, air is filtered by the 0.1 micron filter, and pump into the electric equipment.
