     PRODUCT OVERVIEW

​Under effect of heat and electric field, the exposure of insulation oil contained trace water, gas and particulate matters etc. 
The use of Full-automatic Double-Stage Vacuum Transformer Oil Purifier (Model SINO-NSH VFD-A) is necessary, which will help you maintain optimal oil cleanliness. 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.

Sino-NSH-VFD-A utilizes the brand Programmable Logic Controller (P.L.C.) and a series of instrumentations, alarms and interlocks to provide a fully automatic operation. Manual control of various functions is provided as required. Several Pilot Lights are provided to indicate operational status of key components and alarm conditions. 

BENEFITS:

1. Removes Dissolved Moisture Transformer Oil
2. Reduces combustible gases and oxygen
3. Improves oil dielectric values
4. Improves transformer power factor
5. Extends oil service life
6. Extends transformer service life and reliability
