Application: It is applied to treat various unqualified insulating oils, including aging transformer oil, mutual inductor oil, switch oil ect. Advantages: It's a new-type of high effective vacuum oil purifier with the duplex 3D stereo-evaporation technology and G technology. Adopting the technology, which removes impurities through double FH trapezoidal network and absorbs by high polymer without mechanical power, it's five to eight times more effective than the common vacuum oil purifiers. The consumption of energy is low and it doesn't require other wearing materials. Features: 1 Bi-infrared liquid Duplex 3D stereo-evaporation technology, dewatering and degassing effectively 2 Distinctive removing impurities technology of filtering through double FH trapezoidal network and absorbing by high polymer without mechanical power 3 Bi-infrared liquid level automatic controller system 4 Trinity inter locked preventive device 5 It can work independently, and can also work with the oil regeneration system 6 It can work as vacuum oiling machine or vacuum drying machine to the power equipment, like transformer 7 Automatic testing the oil dielectric strength and printing out the result 8 It can work on line Besides the ZY series, we developed other 3 series for our customers, i.e. ZYA, ZY-W and ZY-M. ZYA means PLC Full Automatic Single Stage VacuumTransformer Oil Purifier, ZY-W means Enclosed Weather Proof Type Single Stage Vacuum Transformer Oil Purifier, and ZY-M Enclosed Mobile Type Single Stage Vacuum Transformer Oil Purifier.
