Product Description


Rexon ZYD-II-200 Mobile Trailer Type Transformer Oil Regeneration System, also known as Fuller's Earth Regeneration Equipment, is a specialized solution designed for the purification and regeneration of old transformer oil. It can effectively remove contaminants such as moisture, dissolved gases, sludge, and acids that accumulate in transformer oil over time.


ZYD-II-200 transformer oil regeneration system can deal with all different grades of KV oil. For both low-voltage oil and high-voltage oil, it can perform a very highly efficient oil purification, oil filtration and oil regeneration work. All insulating oils like used transformer oil, mutual inductor oil, switch oil and so on can be totally regenerated from oil to be new by our ZYD-II-200 plant.


As an important on-site transformer oil cleaning and transformer maintenance system, this plant can inject oil into the transformers online too. It can be used as an independent vacuum resource plant to vacuum transformers high efficiently.

1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa.

2. Oil Regeneration Devices for oil color, acid and oil smell reconditioning.
3. Big capacity of moisture and gas separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength of oil improving greatly.
4. Duplex-stereo film evaporation technology, combined with unique and advanced dewatering, and degassing components, can rapidly and effectively separate water, and gas from oil.
5. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies, which can purify oil highly efficiently and make oil highly pure.
6. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
7. Double-infrared liquid level sensor, pressure protective system, and foaming elimination system to ensure the machine operates easily and safely.
8. Adopt an interlocked protective system, which connects the oil pump, heater, and liquid level sensor, avoiding blank heating, blank pumping, oil leaks, and electricity leaks. If there is any fault, the machine will be powered off automatically.
9. It can be operated both online and offline by transformers.
10. Can be used independent device for vacuuming transformers that are above 110KV and can vacuum oil filling for power equipment.
11. Can work online for 150 hours continuously, highly reliable and long time running.
12. PLC programming control system and touch screen to achieve machine working fully automatically (Optional).

13. Mobile trailer and weather-proof enclosure design, easy to move, and protect the machine in good condition.

By regenerating the transformer oil, it restores the oil's original quality, ensuring optimal performance of the transformer. And helps extend the lifespan of transformers, reducing the need for costly replacements and increasing overall operational efficiency.
