ZYD-W Transformer Oil Purifier with Enclosed Doors

Quick Details

Power supply: 380V 50HZ 3Ph (As per user’s power supply)

Water content: ≤ 3 ppm

Gas content: ≤ 0.1%

Particles size: ≤ 1μ

Application: to purify transformer oil, switch oil, mutual oil, cable oil, capacitor oil etc.


ZYD-W Enclosed Type Of Transformer Oil Purifier. It equipped with dust-proof and water-proof doors. ZYD-W Enclosed Type Of Transformer Oil Purifier can quickly remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil’s dielectric strength, effectively making sure electric equipments working safely and normally. ZYD-W transformer oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than 110V substation live line work onsite. Meanwhile, ZYD-W oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.

Main features:

  • ZYD-W is dust-proof and water-proof type of oil purifier, it is easily move and can be used indoor and outdoor environments.
  • Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa.
  • Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
  • Double-horizontal film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
  • Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies.
  • Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
  • Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
  • 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.
  • Functions of live line work onsite, vacuum drying and vacuum oiling.
