ZJB Single-stage Oil Filtration Equipment,Insulation Oil Filter Machine

We can offer two kinds of machine for treating the waste transformer oil,insulation oil and dielectric oil, which is ZJB Single-stage vacuum oil purifer machine and ZJA Double-stage transformer oil purifier machine.


This high vacuum oil purifier performs the function of upgrading and reconditioning of insulating transformer oil by means of removing impurities such as dust,gas,sludge,water etc. The major operation is heating, filtering, degassing and dehydration. After recycling, it can boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which have insulation system. This machine specialize in purifying transformer oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is also suitable for treating low viscosity lubrication oil.


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

2.With Vacuum pump and Roots pump.

3.Enhance the value of breakdown voltage greatly.

4.Easy handling and maintenance.

5.Inject oil into the transformers.

6.Lower maintenance and replacement expenses.

7.Automatic reverse-washing system will extend the lifetime of filters and improve the performance of the filters.

8.High performance security system including pressure protection device and automatic temperature controller makes purifier operate safely.

9.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.


Dehydration (Degas) System

1, The vacuum chamber has flash tower, which can evaporate the water efficiently. Also it has the spraying nozzle with degassing elements design. The heater, being placed on the vacuum vessel, becomes an evaporator. Thus the flash tower of vacuum vessel is three times more than that of the general vacuum vessel. This innovation can dehydrate and degas effectively and efficiently.

2, The optimal structure of the dehydration (degas) system enlarges the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization.

Filtering System (particulate matter removal)

1, The filtering materials with variable apertures are made of specialized glass fiber. The sizes of the filtering fiber and aperture dwindle gradually in the different filtering stages. The impurities with different particulate sizes are filtered step by step. The capability of removing particulate matters and impurities is improved greatly by this method.

2, The filtering system has stable and prefect filtering fineness. The filtering fineness has several grades, including 1, 2, 3, 5, 6, 10 Micron etc. Oil β>=1000 after filter.

3, The filtering system is equipped with reverse rinse and filth device. It improves the effectiveness of filtering and extends the lifetime of filter awfully.

Oil heating System

1, The unique heater structure heats the oil uniformly.

2, Oil Heater System assures less then 1.0 w/cm2. During the heating process, the deterioration of the oil caused by overheating is avoided.

3, The oil temperature can be adjusted between 20C to 80C. The heater is controlled manually or automatically. The heater will stop automatically when the oil temperature reaches a certain degree.

4, 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.

Electrical Apparatus Controlling System

1, The main components of the electrical apparatus made by Schneider, Siemens and so on ensure the safety of the controlling system.

2, Having several protection systems which will avoid oil ejection, overload and over voltage etc.

Oil-level Controlling System

1, 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.

2, The new innovation of eliminating froth can avoid the oil being suctioned into vacuum pump.

Vacuum Pump

Rotary Vane Vacuum Pumps, is a basic equipment used for pumping air from sealed vessels to attain vacuum condition.


Ultimate pressure:less than 6*10-2Pa

Rotary speed of pump:520 R/Min

Motor Power: 1.5Kw

Cooling mode: water cooling, >1L/min

Roots Pump

Roots pumps can be used as boosters combined with backing pump. Of a rotary vane vacuum pump,or a liquid ring vacuum pump.


Ultimate pressure: 5*10-2Pa

Rotary speed of pump: 2880r/min

Motor Power: 3Kw

Cooling mode: water cooling, >2L/min

Breakdown Voltage Tester(Option)

Computer controlled and fully automatic, which via proper digital programming, it could desired number of tests and time of stirring standstill. Printed out of test result is available; it is an ideal device to test insulator withstand voltages.

Printer output

Input voltage: AC 220v

Output voltage: AC 0—80kv

Voltage rising rate: 2kv/s±10%

Test precision: 1.0grade

Test times: 1---9, stirring time: 0---99seconds, stewing time: 0---9 minutes 59 seconds

Different between ZJA & ZJB





Double stage with a ROOTS PUMP and vacuum pump

Single stage only with vacuum pump

Vacuum degree



Breakdown voltage

of the oil after treatment



Water content of the oil

after treatment



Smallest capacity



The Difference of Single Stage ZJB and Double-stage ZJA are following:

1. ZJA is more applied to process ultra-high transformer oil, especially used to large power transmission and transformation equipment more than 110KV, but ZJB mainly treat the oil less than 110KV.

2. The speed of ZJA is faster than ZJB

3. ZJA can remove Acetylene and Firedamp more thoroughly and quickly;

4. The index of oil breakdown voltage is different, ZJA is more than 75KV, but ZJB only 60-65KV.
