The principle function of ZYD series vacuum transformer oil purifier/ oil filtration/ oil purification/ oil regeneration/ oil recovery/ oil recondition/ oil reclamation/ oil dehydration/ oil treatment machine,  is the removal of water, gasses, impurities and light hydrocarbons from oil. The operating principle is extremely simple. The system operates under vacuum conditions. The oil is pulled through an electric immersion heater which raises the oil to an optimum temperature. The oil is then forced by atmospheric pressure into the vacuum chamber. There it passes from the Duplex 3D stereo-evaporation device, which can maximum surface area exposure and speed up water removal, the rest solid waste will be filtered by fine filter when the oil coming out of the vacuum chamber. While the oil is exposed to the vacuum, water (free, dissolved, and emulsified), dissolved gasses and air, and other low range volatiles are vaporized out of the oil, and after the last process of fine filtration, leaving a purified and conditioned oil to safe operating standards. The vaporized gasses are pulled off by a rotary vane vacuum pump through a small trap where some of the condensate is collected. The remaining vapors are exhausted to atmosphere. 

1: It is for treating various insulating oil, including transformer oil, mutual inductor oil, switch oil. 

2: It is widely applied in large scale manufacturing factory, power station and other related industrial fields which will use transformers, especially for over 110 KV transformers. 

3: Double stage vacuum system, adopt international advanced duplex stereo-evaporation technology and UK G technology to eliminate the trace water in insulation oil and recover its breakdown voltage greatly. 

4: Adopt Germany's 3 UG phase replay, can make the machine working efficaciously and safely at any situations, such as power off, lack of phase, wrong phase position, etc. 

5: Equipped with advanced dielectric condensation devices for greatly prolong the oil purifier service life. 

6: A trinity of interlocked preventive device is applied for avoid the machine being damaged from any accident automatically. 

7: It also can be used as a separate vacuum system for dehydrating oil only, don't need to run all process and can save time and consumption for different request on oil filtration. 

10: It can be moved easily with equipped steel wheels; it also can be designed for different structure of fully enclosed type and fully enclosed + trailer type for the purpose of outdoor use and indoor use. 

11. Various color of this model can be produced just as customer’s favor.
