Application: 
  ZYD 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. 
  ZYD series specialize in purifying branded oil, insulating oil of high voltage and superhigh voltage
   transformer. 
  Additionally, it is suitable for treating low viscosity lubrication oil.
  Description: 
  ZYDseries utilizes coacervation technology, coalescing technology,separating technology
   and refined purification technology.
  Comparing to ZYseries, it adds a ROOTS vacuum system, second stage of separating 
  system to improve the effect of purification and to remove free, soluble water, carbon,free 
  and dissolved gases and particulate matters from insulating oil effectivelyand rapidly.
