ZJA is double stage vacuum transformer oil purifier, which contain vacuum pump and roots pump. We can do more big capacity of machine, and the smallest one is ZJA-30, 1800L/H, The biggest one is more than 30,000L/H. The machine is adopted the rustproof and moisture film and wood cases packages. We can take special order for you, like the machine face, color, weight, size, filter precision, filter numbers, spare parts, oil specification tester, etc.
1) For maintenance of large scale power substation transformers, rapid and deep treatment of new transformer oil, imported insulation oil. As well as vacuum filtering and purifying of mutual inductor oil, capacitor oil, refrigerator oil.
2) Especially suitable for purifying of large scale power transmission units higher than 75KV and transformers of main state grid.

- Advantage of Structures (ZJA)
- To remove free, soluble water, carbon, free and dissolved gases and particulate matters, dust from insulating oil effectively and rapidly.
- With Vacuum pump and Roots pump.
- Enhance the value of breakdown voltage greatly.
- Easy handling and maintenance.
- Inject oil into the transformers.
- Lower maintenance and replacement expenses.
- High performance security system including pressure protection device and automatic temperature controller makes purifier operate safely.
- 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.
- Can design the machine according to your requirement, add weather-proof cover, close/open ventilation window, skid basic mounted and enough lifting hook
- Also can add 2 pneumatic tires and 1 pre-leg, it’s convenient to move at any site.
