Oil Purifiers

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

UVP Ultra high Voltage Transformer Oil Purification Equipment

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.


UVP Ultra-high Voltage Transformer Oil Purification Equipment is Especially for ultra-high voltage project as ( 1000KV, ±800KV, 750KV, ±660KV) Substation Maintenance Contractors and Utilities need an oil filtration machine that can quickly and reliably process transformer oil to meet or exceed very stringent specifications,

In order to achieve optimal dielectric strength and insulating performance inside of transformers and circuit breakers, dielectric oils must be kept absolutely clean and dry;

ZANYO designs and manufacture the most effective, durable, and user-friendly machine running and serving customers in 40 more countries with good reputation.


Degassing: to remove other dissolved combustible gases such as Acetylene, Ethylene, Ethane, Methane, Hydrogen and Carbon Monoxide, and Carbon Dioxide.

Dehydrating: to remove free and dissolved water, including insulation dry-out of the windings.

Decoloring and recycling: to remove acids and particulate material.

Outstanding Technical Features:

  • Specially designed the evaporation chamber, to make larger space for degassing and dehydration.
  • To adopt with auto- pressurization defoaming technology, more than 200 hours of continuous operation without bubbles rise.
  • Unique technology: Atomizer is placed inside at the bottom of the chamber, to increase the evaporation area and extend the degassing time.
  • To adopt vacuum balance pressure technology, vacuum pumping efficiency increased by 50%.
  • Advanced level control system, continuously oil supply to prevent oil pyrolysis.
  • Advanced level control system.
  • PLC controlling system.
