The machine is mainly used for electric power department and industries to deal with various oils such as transformer oil, mutual oil, switch oil, dielectric oil and so on. It also can be used for filtration of more than 110KV substation live line work onsite. Meanwhile, as the bridge-type vacuum linking system, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling. ● 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, sensitive automatic pressure 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 fiber 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.
