NSH 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.
NSH VFD series utilizes coacervation technology,coalescing technology,separating technology and refined purification technology.Comparing to Model VF series,it add ROOTS Vacuum system,second stage of separating system to improve the effect of purification. To remove free,soluble water,carbon,free and dissovled gases and particulate matters from insulating oil effectively and rapidly.
VF Single-stage transformer oil purifier
VFD Double-stage transformer oil purifier
VFD-R Double-stage transformer oil regeneration purifier
