Double-stage highly effective vacuum Insulation oil purifier Series ZYD: Application: (oil filtration, oil purification, oil recycling, oil treatment, oil regeneration, oil restoration, oil filtering, oil filter, oil purifier, oil purify, waste oil disposal, oil reclaiming, waste oil management, energy saving, oil reconditioned, oil reconstituted, oil restituting, oil recovering) The machine can remove the water, gas and impurities in insulation oil high-efficiently, increasing the pressure force and quality of oil, make sure the electric device running safely. The machine is mainly used for electric power department and industries to deal with various oils such as transformer oil, mutual oil, switch oil and so on. The machine is especially for purifying the insulation oil in all kinds of large power equipments that are above 110KV. Feature: 1. This machine is high effective and portable, which is very suit to operate on line. Also it can be used to dry the electric equipment and input the oil into the electric equipment under the vacuum state. 2.The machine adopts the double-infrared liquid automatic controller, pressure automatic-protector and the high effective equipment for degas, so it is easy to operate. 3. High vacuum limiting vacuum less than 5pa, working vacuum less than 35pa. 4. High absorption speed, absorption speed power more than 333L/Sr. 5. Duplex 3D stereo-evaporation technology, eliminating the liquid water very effectively. 6. UK G technology by which the trace water that is show chain, such as dissolved water, can be removed effect. 7. Distinctive removing impurities technology filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power. 8. Carbon fibre infrared heating system that can make the oil contains zero sum of ethyne after treatment. 9. The oil of any grades can be treated on line at the working site. Advantage: Comparing with the single-stage vacuum oil purifier, this machine dewaters, degases and removes impurities more quickly, more completely and make the oils limiting voltage-withstand value much higher. As the bridge-type vacuum linking system that can filter and be an independent vacuum power supply, this machine can be vacuum treating the electric insu
