Under effect of heat and electric field, the exposure of insulation oil contained trace water, gas and particulate matters etc. 

The use of 
Vacuum Transformer Oil Purifier (VFD) is necessary, which will help you maintain optimal oil cleanliness. Therefore, making the most use of your equipment to gain the highest and save your money.

Application of Transformer Oil Purifier 

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 purifyingbranded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.

Description of Transformer Oil Purifier

SINO-NSH-VF -- Single-Stage Vacuum Transformer Oil Purification Machine

SINO-NSH-VFD -- Double-Stage Vacuum Transformer Oil Purification Machine 

SINO-NSH-VFD-R -- Double-Stage Vacuum Transformer Oil Purification & Regeneration Machine

SINO-NSH-VFD-A – Full-automatic Double-Stage Vacuum Transformer Oil Purification Machine

SINO-NSH-VFD utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. Comparing to SINO-NSH-VF, 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.For the treatment of aging transformer oil and deteriorated transformer oil, we recommend SINO-NSH-VFD-R to regenerate them.
