ZYD is special for treating the used and old transformer oil, mutual oil, switch oil. Comparing with the single-stage type, this machine adopts the double stages vacuum system, which can improve the machine's working vacuum value highly, so this transformer oil regeneration system  can dewater, degas and remove the impurity more deeply and effectively. The dielectric value of treated oil is higher than 65KV. It is very suitable for the large electric&insulation equipments. Feature:1. High vacuum regeneration: High point-Vacuum≤5pa Working-vacuum≤35pa 2. High absorption speed: Absorption speed power≥333L/Sr.3. Duplex 3D stereo-evaporation, eliminating the liquid water quickly 4. Distinctive removing impurity system which filters the impurity through double FH trapezoidal network and absorbs the impurity by high polymer without the mechanical power 5. Carbon fiber infrared heating system that can have the oil contain zero sum of ethyne after the treatment 6. Especially applied to vacuum filling oil and drying for power transmission equipments which power are over 110KV7. Any insulating oil can be treated on-line at the working site.Advantage:Comparing with the single-stage vacuum transformer oil regeneration system, this machine dewater, degas and removes the impurities more quickly, more completely, and makes the oils limiting voltage-withstand value much higher. As the bridge-type vacuum linking system that can purify and also can be an independent vacuum power supply, this machine can treat the electric insulation devices.Our Main Products: Series ZY Single-Stage Vacuum Transformer Oil Purifier Series ZYD Double High Vacuum Transformer Oil Purifier Series ZYB Multiply-Function insulating oil treatment machine Series TY Turbine Oil Purification Apparatus Series TYA Lubricating oil/ hydraulic oil purification unit Series LYE Engine oil recycling system Series TYB Portable light Fuel oil purification machine Series PL Plate pressure oil purifier Series TYD Vacuum dehydrator Series EFD Explosion protection filtration machine Series JL Portable oil filtering and oiling machine Series IIJ Oil Tester (BDV Tester) .E-mail: chinaoilpurifier@gmail.com           chinaolipurifier@hotmail.com
