Application: This machine is designed for treating wide range of unqualified insulating oil, including aging transformer oil, mutual inductor oil, switch oil ect. Features: 1.Bi-infrared liquid duplex 3d stereo-evaporation technology, dewatering and degassing effectively 2.Distinctive removing the impurity technology of filtering through double fh trapezoidal network and absorbing by high polymer without the mechanical power 3.Bi-infrared liquid level automatic controller system 4.Trinity inter locked preventive device 5.Either for vacuum oiling machine or vacuum drying machine 6.Automatically testing oil dielectric strength and printing out the result Advantages: This machine is a new-type of high-effective vacuum oil purifier with the duplex 3d stereo-evaporation technology and g technology. Adopting the technology which removes the impurities by using double fh trapezoidal network and high polymer absorbing without any mechanical power. It has 5-8 times effective than common vacuum oil purifiers. Low consumption of energy and less wearing materials are needed. Wooden
