Oil Purifiers

Oil filtration equipment for transformer oil, lube oil, turbine oil , cooking oil.

ZYJL-S Portable Vacuum Insulation Oil Purifier

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


ZYJL-S Portable Vacuum Insulation Oil Purifier is single stage vacuum oil purifier, it is used for removing moisture, gas, particles from the transformer oil, insulating oil, switch oil, cable oil, and electric condenser oil. In this way, it can improve oil dielectric strength very quickly and effectively. ZYJL-S vacuum oil filtration machine is mainly used for the power station, industrial and mining enterprises.

ZYJL-S can be used to power equipments to vacuum drying, and vacuum oiling. It will be easy to move and light weight.

Technical Features:

  • Especially designed evaporation chambers, to make larger space for degassing and dehydration.
  • Unique technology: Atomizer is placed inside at the bottom of the chamber, to increase the evaporation area and extend the degassing time.
  • Adopt with auto- pressurization defoaming technology, to ensure the more than 200 hours of continuous operation without bubbles rise.
  • Using high-density heater, heating load is less than 2w/cm2; in this way, to lower down the surface temperature of heater, to prevent oil ageing and oil cracking.
  • Controller with powerful management functions, PID regulation technology along with level sensor and temperature protector, completely protect heater from high surface temperature.
  • Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies, solid particle interception rate can achieve 99.99%.
  • The cooler is in front of vacuum pump, to reduce water enter into the vacuum pump; in this way, to protract the lifetime of vacuum pump.
  • Foam sensor can monitor foams when machine working.
  • Adopts interlocked protective system, which connects 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.
