as well as purify mutual inductor oil, switch oil and so on.

These equipment are suitable for cleaning of contaminated transformeroil, cable oil and insulating oil,etc.

Depending on type contamination equipment are designed using combination ofprocesses such as vacuum oil purifying, degassification, coalescing andfiltration

Meanwhile, Series ZYD oil purifier can be used as independent vacuumsource with functions of vacuum drying and vacuum oiling.


1.Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuumvalue < 5Pa

2. Two vacuum separating chambers, efficient oil film sprayer, increasingseparating size and separating time to ensure the dry-level and dielectricstrength improving greatly.

3. High Vacuum Tower With Coalescer Elements

4. Duplex-Stereo film evaporation technology, combined with unique andadvanced dewatering, degassing components, can rapidly and effectively separatewater, gas from oil.

5. Multi-stage precision filtration system, mesh filtration combined withmolecular adsorption technologies 6. Efficient electric heating system, heatinguniformity, less power consumption, safe, and reliable. 7. Double-infraredliquid level sensor, pressure protective system to ensure machine operation easyand safely.
