VFD-Double-Stage High-Efficiency Vacuum Insulation Oil Purifier Application(oil filtration, oil purification, oil recycling, oil treatment, oil regeneration, oil restoration, oil filtering, oil filter, oil purifier, waste oil disposal, oil reclaiming, waste oil management, energy saving, oil reconditioned, oil reconstituted, oil restituting, oil recovering, oil recuperation, oil filtrating, used oil, industrial oil, oil remediation, oil processing, oil remediation) VFD 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. VFD series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.
