application oil filtration, oil purification, oil recycling, oil treatment, oil regeneration, oil restoration, oil filtering, oil filter, oil purifier, waste oil disposal, oil reclaiming, waste oil management, energy saving, oil reconditioned, oil reconstituted, oil restituting, oil recovering description 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. insulation oil series vid double-stage high-efficiency vacuum insulation oil purifier vid-a double-stage vacuum insulation oil automation purifier vid-r double-stage vacuum insulation oil regeneration purifier vi vacuum insulation oil purifier vi-a vacuum insulation oil automation purifier vi-r vacuum insulation oil regeneration purifier turbine oil series vt vacuum turbine oil purifier vt-a vacuum turbine oil automation purifier hydraulic oil series vh vacuum hydraulic oil purifier vh-a vacuum hydraulic oil automatic purifier
