Product Description
Transformer oil purifier, Zhongneng High precision transformer oil purifier


1. Used oil waste oil recycling, Zhongneng more than your expect used oil waste oil recycling machine is designed for purifying used or aged transformer oil, Altrahigh-voltage transformer oil, switch oil and other insulating oils.

2. It is very suitable for power distribution station, power grid and various companies which need to install and maintain oil-immersed transformers.

3. Besides the regular transformer oil purification, this machine can be also used as vacuum oil injection and vacuum drying equipment for transformers, and it is cost-effective, easy to operate.


1. Besides vacuum pump, this machine installs Roots Pump vacuum system, which speed up air evacuation, make limited vacuum ≤ 5Pa, working vacuum ≤ 35Pa.

2. Large area three-dimensional flash distillation technique, advanced dewatering and degassing system, which remove water and gas rather quick and complete.

3. Precise filtration system, high-quality filter element, multi-stage filtration with gradual precision, which help removing mechanical impurities from oil.

4. After purification the breakdown voltage of transformer oil can reach up to 70KV.

Technical Parameter

5. Advanced double-infrared liquid level automatic controller, pressure automatic-protector, which ensure long- term safe and reliable operation.

6. This machine can be operated both on-load and off-load.

7. Humanization design, low noise pump, deep purification and long-term free technical instruction.

8. General type, Trailer-mounted type, Hermetical type, etc, which is available.


Comparing with the single-stage vacuum oil purifier, this machine dewaters, degases and removes the impurities more quickly and completely, and improves the oil breakdown voltage much higher. As the bridge-type vacuum linking system, it is used for filtration system as well as an independent vacuum power supply to vacuum oiling for power equipment.
