We offer transformer oil purifier. zyd series double-stage vacuum transformer oil purifier is designed for purifying used or aged transformer oil, super high-voltage transformer oil, switch oil and other insulating oils. it is very suitable for power distribution system, power grid and various companies which need to install and maintain oil-immersed transformers. the zyd system not only provides regular oil purification/ reclamation such as degassing, drying and particulate removal, but also can remove acidity, sludge, carbon deposits, other soluble oil decay products and discoloration. this is accomplished by the use of high vacuum degasification technology and particulate filters combined with our special brand of earth. After treating, the oil can be reused as new. besides the regular transformer oil purification, this machine can be also used as vacuum oil injecting and vacuun drying equipment for transformers, and it is cost-effective, easy to operate. features: 1. Besides vacuum pump, this machine installs roots pump vacuum system, which speed up evacuation, make limiting vacuum ≤ 5pa, working vacuum ≤ 35pa. 2. Large area three-dimensional flash distillation technique, advance dewatering and degassing system, which remove water and gas much quickly and completely. 3. Precise filtration system, high-quality filter element, multi-stage filtration with gradual precision, which help removing mechanical impurities in the oil. 4. After purification the breakdown voltage of transformer oil can reach up to 75kv. 5. Advanced double-infrared liquid automatic controller, pressure automatic-protector, which ensure long-term safe and reliable operation. 7. This machine can be operated both on-load and off-load. 8. Humanization design, low noise pump, deep purification and long-term free maintenance. 9. General type, trailer-mounted type, hermetical type, flow meter etc. Is available. other products: 1 insulating oil purifier series zy: zhongneng vacuum insulating oil purifier series zy-a: zhongneng vacuum insulating oil automation purifier series zy-r: zhongneng vacuum insulating oil regeneration purifier series zyb: zhongneng multi-functional oil purifying machine series zyd: zhongneng double-stage vacuum transformer oil purifier series zyd-a:zhongneng double-stage vacuum transformer oil automation purifier series zyd-r: zhongneng double-stage vacuum transformer oil regeneration purifier series zyd-m: zhongneng mobile type transformer oil purification plant, oil recycling series zyd-e: zhongneng enclosed type transformer oil purification plant, oil recycling 2 turbine oil purifier series ty zhongneng vacuum turbine oil purifier series ty-r zhongneng vacuum turbine oil regeneration purifier series ty-a zhongneng vacuum turbine oil automation purifier 3 lubricating oil purifier series tya: zhongneng vacuum lubricating oil purifier series tya-r: zhongneng vacuum lubricating oil regeneration purifier series tya-a: zhongneng vacuum lubrication oil automation purifier series tya-i: phosphate ester fire-resistant oil purifier 4 engine oil purifier series lye: zhongneng vacuum engine oil purifier 5 diesel oil, gasoline oil and fuel oil purifier series tyb: zhongneng diesel oil, gasoline oil and fuel oil purifier 6 transformer oil regeneration device series bz: zhongneng bz transformer oil regeneration device 7 oil purifier specially for hydraulic oil and lubricating oil series tya: zhongneng oil purifier 8 pl plate pressure oil purifier 9 jl portable oil purifying 10 tyd water oil separator, oil purifier machine 11 fully automatic insulating oil dielectric strength tester (bdv tester)
