Application:
ZYD double stage vacuum transformer oil purifiers are designed for use in treating electrical insulating oil in the oil-filled electrical equipment. As the oil purifying nanotechnology, this machine can treat oil more quickly and more completely, and makes the oil limiting voltage-withstand value much higher than the ordinary vacuum oil purifier.
It also can be used for filtration of more than 110V substation live line work onsite. Meanwhile, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling. Features:
1. Double-Stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value no more than 5Pa
2. Two vacuum separating chambers, efficient of film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
3. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas, from oil.
4. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies.
5. Efficient electric heating system, heating uniformity, less power consumption, safe and reliable.
6. Double-infrared liquid level sensor, pressure, protective system to ensure machine operation easy and safely.
7. Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping.

Advantge:
1. Fully automatic 24 hour continuous operation, enables unattended supervision
2. Oill foam will be eliminated quickly in the process of treatment
3. Oil spraying type with large vaporization surface in vacuum chamber
4. Utilization of low load heater to avoid oil deterioration in the process
5. All necessary control switch, light indicator and meter are equipped on the control panel which provides easy control for operation and supervision
