Vacuum Oil Purifier

ZYD series vacuum oil purifier, also called as transformer oil purifier, vacuum oil filtration machine, transformer oil filtering machine, is a typical double-stage vacuum filtering machine, special for dehydrating, degassing and purifying different kind of insulation oils used in high voltage transformers and circuit breakers, etc.

I Main features

-Double-stage, high vacuum pressure and high flow rate that helps remove water, air and gas, solid particulates and other impurities from oil quickly and efficiently so as to improve the break-down voltage of oil and maintain its insulation property.

- Advanced dehydrating and degassing system that uses large area 3D flash distillation technique to remove harmful composition in the oil, such as water, air and gases.

- Precise fine multi-stage filtration helps remove mechanical impurities in oil; high quality filter elements are of corrosion proof, strong mechanical strength and wear resistance.

- Sensitive automatic pressure protection device and infrared oil level control system make the operation even easy, simple and safe.

- It possesses the function of vacuuming electrical equipment and oil filling under vacuum condition. It can be used to treat low-viscosity lubricating oils. It is more efficient than other single-stage vacuum oil purifier.
