Aosen VID series (Double-Stage High-Efficiency Vacuum Insulation Oil Purifier Series) are mainly used to filter different insulation oil. The series adopt two-stage pump to improve the degree of vacuum furthest so that they can efficiently eliminate the water, gas (C₂H₂) in the insulation oil. The filtering system which contains three-stage filtering devices can eliminate various impurities. At the same time, the regeneration purification system can eliminate the oil sludge, free carbon and other deleterious materials which affect the working order of transformer so that the acid value and the cost of insulation oil are recovered. The advanced automatic programmable logic controller (PLC) can control the whole process of oil purification so that improve work efficiency and quality. The series can choose configuration compounding and the parts of each system according to the customers¡¯ requirement. If the customer has special requirement, our company can support different types such as professional explosion protected type, close type, trailer type, vehicle type etc.
