Application:
ZYD double stage transformer oil purifier is widely used in electric power, transforming electricity industry, metallurgy, chemical engineering, traffic, railway and others. It is designed for the vacuum filter of expensive oil such as fresh oil, imported oil, instrument transformer oil, extra-high tension transformer oil (cover110v, major transformer), and for vacuum oiling, and drying of transformers. This filter can live line work on the spot.

Features:
1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value < 5Pa
2. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
3. High Vacuum Tower With Coalescer Elements
4. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
5. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
6. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
7. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
8.Adopt interlocked protective system,which connect oil pump,heater and liquid level sensor,avoiding blank heating,blank pumping.
9.Functions of live line work on-site,vacuum drying and vacuum oiling.



Advantages:
According to the transformer oil change it is very economic
Used transformer oil can be brought up to the equivalent point of new oil
Transformer within
As a result of the occurrence waste oil and disposa the moisture, sludge, acids and harmful gases to destroy and the insulation values will be higher than old.
Transformer oil life is extended. l costs would have been zero.
Waste oil has been blocked and prevented its negative given for the enviroment.
