Application VFD(insulation oil purifier,Oil Regeneration, Oil Purification, Oil purify, Oil Recovery,Oil Processing,Oil Filtering,Oil Filtration, Oil Treatment,Oil Recycling,Oil Restoration,Oil disposal, Oil Reclamation) series is mainly used to improve the properties of insulation oil. It can remove 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 oil filtration series is specialized in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil Description Model VFD series utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. Comparing to Model VF series, it adds ROOTS vacuum system, second stage of separating system to improve the effect of purification, to remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly
