ZYD Series Double-Stage Vacuum transformer Oil filtration machine can quickly and effectively remove moisture, gas (Hydrogen, acetylene,methane, etc.) and impurities from the insulation oil, to improve the oil dielectric performance. The filtered oil can effectively ensure the power equipment run safely and normally. ZYD Double-stage vacuum oil purifier is widely used in power supply, power generation, power transmission and transformation, power equipment manufacturing, power engineering, electrical equipment maintenance, power testing, electrical research and other industries. It is especially suitable for the filtration of high-grade transformer oil and ultra-high transformer oil, and can be applied to online oil filtering operations at the power substation (like 110KV / 220KV / 500KV). Meanwhile, ZYD oil purifier has the functions of vacuum drying, vacuum oil injection, and hot oil circulation. It can also be used as a separate vacuum pumping unit to evacuate transformers and power equipment.

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. Double-horizontal 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, oil leak and electricity leak. If there is any fault, machine will be power off automatically.


8. Functions of live line work onsite, vacuum drying and vacuum oiling.
