Application:
ZYD has been specially designed for on site use tocompletely regenerate insulating oils in energized or de-energized transformerseven when transformer power above 110KV and altitude over 500 meters, as well aspurify mutual inductor oil, switch oil and so on.
These equipment aresuitable for cleaning of contaminated transformer oil, cable oil and insulatingoil,etc. Depending on type contamination equipment are designed usingcombination of processes such as vacuum oil purifying, degassification,coalescing and filtration
Meanwhile, Series ZYD oil purifier can be used asindependent vacuum source with functions of vacuum drying and vacuum oiling.

Features:
1. Double-stage vacuum system, strong power of vacuumevacuating, ultimate vacuum value < 5Pa 2. Two vacuum separating chambers,efficient oil film sprayer, increasing separating size and separating time toensure the dry-level and dielectric strength improving greatly. 3. High VacuumTower With Coalescer Elements 4. Duplex-Stereo film evaporation technology,combined with unique and advanced dewatering, degassing components, can rapidlyand effectively separate water, gas from oil. 5. Multi-stage precisionfiltration system, mesh filtration combined with molecular adsorptiontechnologies 6. Efficient electric heating system, heating uniformity, lesspower consumption, safe, and reliable. 7. Double-infrared liquid level sensor,pressure protective system to ensure machine operation easy and safely.

Advantage:
Comparing with the single-stage type, this machine adoptsthe double stages vacuum system, which can improve the machines working vacuumvalue highly, so it can dewater, degas and remove the impurity more deeply andeffectively. The dielectric value of treated oil is higher than 75 KV. It isvery suitable for the large electric & insulation equipments.
