Double Stage 50 Kw Transformer Oil Filtration Purifier 3000L/H Oil
Treatment Machine
General
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
Description
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.

- Lower maintenance and replacement expenses
- High efficiency and effectiveness
- Small size, light weight, low noise
- Various sizes and configurations (shield) available.
Main components
a.Pre-filter:
Utilizes a 50-80mesh strainer to remove any large particles
b. Electric heater:
Oil Heater System assures less than 1.0 w/cm². During the heating
process, the deterioration of the oil caused by overheating is
avoided. The oil temperature can be adjusted between 20℃ to 80℃.The
heater is controlled manually or automatically. The heater will
stop automatically when the oil temperature reaches a certain
degree. Being installed with safety protection devices, the heating
system is secure and reliable. The heater will stop operation
automatically when the oil volume of inlet is too low to avoid the
damages of the heater.
c. Vacuum chamber:
Utilizes coacervation technology, coalescing technology, separating
technology and refined purification technology. To remove free,
soluble water, free and dissolved gases. The oil-level floating
ball or infrared liquid level automatic controller system are
installed in the vacuum vessel to control the oil level so as to
avoid the oil being
suctioned into vacuum pump in the operation. The new innovation of
eliminating froth can avoid the oil being suctioned into vacuum
pump.
d. Oil cooler:
Connected to between vacuum chamber and the roots pump, the vacuum
pump to avoid oil entering roots pump and vacuum pump. Secondly, to
cool the heated air.
e. Oil discharge pump:
Featuring high suction capabilities removes oil from the processing
chamber and discharges the oil through a filter before it is
directed either through the discharge port or is re-circulated
within the system.
f. Fine filter:
Oil receives its final “polishing” treatment by passing through a
high performance element. The filter is rated to capture99.5% of
particles greater from 5 to 10 micron absolute.
g. Sampling probe:
Two (2) sampling probes shall be provided, one for the incoming oil
and one for the processed oil.
h. Inlet&discharge valves:
Manual valves are provided for the inlet and discharge connection.
i. Manual re-circulation valve:
One manual valve is provided for re-circulation purposes.
j. Transformer dry-out connection:
One transformer dry-out connection.
k. Control panel:
Instrumentation, alarms& interlocks instrumentation&electrical
controls are located in NEMA 12 type enclosure. Several pilot
lights are provided to indicate operational status(on/off) of key
components and alarm conditions.
