Brief Introduction About Sino-NSH


Sino-NSH Oil Purifier Manufacture Co., Ltd is a high-tech Company which is engaged in researching, developing and manufacturing lubrication purification equipment. Its parent company, Sino-NSH High-Tech Company, was established in 1992.We can ensure the first-class quality as well as provide the first-class service.NSH has been engaging in oil purifier producing, our products are extensively used in the fields of electric power, petroleum, natural gas, mechanical engineering, metallurgy etc. (www.nshoilpurifier.com)


High Precision Vacuum Transformer Oil Filtration System,

Oil Filter Machine


The necessity for transformer oil dehydration and degassing is know for a long time. Sino-NSH Transformer oil purification plant removes moisture, gasses and solid particles from transformer oils. NSH transformer oil purification plants are built in different sizes with variable flow and highly efficient degassing chamber. Plants are of stationary or mobile design and can work on offline or online transformers. 





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.

Operating conditions:

The installation shall be designed to opeartae satifactory at ambient temperatures ranging from -20 deg.C to 55 deg. C



NSH VFD series utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.


Ⅲ.Edges of VFD series

    1.To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.

    2.Enhance the value of breakdown voltage greatly.

    3.Easy handling and maintenance.

    4.Inject oil into the transformers  

    5.Online work

    6.Lower maintenance and replacement expenses

    7.High efficiency and effectiveness

    8.Small size, light weight, low noise

    9.Various sizes and configurations (shield) available.


IV.Specifications of VFD





Relative Series:
VFD series: Insulation Oil Purifier Series
TF series: Turbine Oil Purifier Series 
LV series: Lubrication Oil Purifier Series
GER series: Used Engine Oil Regeneration System


VFD series: Insulation oil purifier System specialize in purifying branded oil, insulation oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.
TF series: Turbine oil purifier system is particularly suitable for purifying turbine lubricating oil. It  also applys to treat hydraulic, coolant oil and other lubrication in which contain large of water, vapor, impurities, sludge, dielectric and colloid. It can eliminate them effectively and efficiently.
LV series: Lubrication Oil Filter System are suitable especially for purifying and restoring hydraulic oil, machine oil, coolant oil and various other lubrication oil.
GER series: Used oil regeneration system is suitable to regenerate used internal-combustion engine oil including diesel engine oil, gasoline engine oil, and used hydraulic oil, other used lubrication oil of machinery.


Relative Parts:

1. Foam Level Detector
When there is foam in the tank and foam reaches a certain level (resetable), a signal will be sent to the magnetic valve, the magnetic valve will automatically shut on. The foam will be removed quickly. After removing foam, the magnetic valve will shut off.
2. Digital Vacuum Gauge (Pirani gauge)
Display Type: Digital
Accuracy: ±1.0%
3. Digital Hygrometer(water or moisture in oil tester) On-line type
Measure Scope: 0—100 PPM
Display Type: Digital
Output Signal: one is PPM, the other is temperature.
4. Digital Flow Meter Display Type: LCD
Mode: 1) accumulative total value 2) online flow value 3) accumulative total value for each time (reset adjustment)

5. Transformer Oil BDV Tester 

Output Voltage:AC 0-80KV or AC 0-100KV
