1.Apply to waste/used transformer oil, 2.Enhance the value of breakdown voltage greatly, 3.Easy handling and maintenance - details see: https://www.machineto.com/two-stage-dielectric-oil-filtration-machine-oil-refinery-10227735

Nsh VFD oil purifier series is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. From the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system. Nsh VFD oil purification series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformers. Additionally, nsh VFD oil treatment plant is suitable for treating low viscosity insulation oil.
