This oil recycling system is applied to treat various of unqualified insulation oils including aging transformer oil, mutual inductor oil, switch oil. Also it can inject the insulating oil into the transformers. The functions includes dewatering, degassing, removing the impurities, and recovering the oil's original function. Features 1. Distinctive removing the impurities technology filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power. 2. Bi-infrared liquid Duplex 3D stereo-evaporation technology, dewatering and degassing very effectively. 3. uid automatic control. 4. A trio of inter locked preventive device. 5. This machine can work independently, also it can work with the oil regeneration system 6. Vacuum oiling of power equipment and drying moisture of power equipment 7. Automatic testing voltage-withstand system and printing out the result 8. The oil of any grades can be treated on line at the working site Advantage It's a new-type of high effective vacuum oil purifier with the duplex 3D stereo-evaporation technology and G technology. Also it adopts the technology, which remove the impurities through double FH trapezoidal network and absorbing by high polymer without the mechanical power. So it's five or eight times as effective as the common vacuum oil purifiers, the consumption of energy is least and it's doesn't need other wearing materials.
