As is well known the Transformer plays an important role in the generation, transmission and distribution of electrical energy. Under load the transformer, dissipates heat and the insulating oil acts as a coolant as well as an effective dielectric.
Due to the highly hygroscopic nature of the transformer oil, it absorbs moisture from windings, which leads to gradual deterioration of dielectric strength. Also there are some waste impurities, gas contents in the transformer oil which destroy the oil’s quality.
Series ZYD transformer oil purifier is a double stages vacuum oil purification system, comparing single stage vacuum oil puriifer, besides a rotary vane vacuum pump, ZYD machine installs one more booster roots pump vacuum system which speed up evacuation much faster. Series ZYD oil filtration machine not only provides regular oil purification/ reclamation such as degassing, drying and particulate removal, but also can remove acidity, sludge, carbon deposits, sulfur, and other soluble oil decay products and improve physical & chemical properties comparable to new transformer oil.
The doube stage vacuum transformer oil purifier adopts advanced vacuum chamber which has large area three-dimensional flash evaporation technique and remove water, gas, solids much quickly and completely. After purification by our Series ZYD transformer oil purifier, the oil breakdown voltage can reach up to 75KV.
Series ZYD 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, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.

Duplex 3D stereo-evaporation, efficient oil film sprayer, eliminating the liquid water quickly, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
Double-stage vacuum system, strong power of vacuum evacuating
Multi-stage precision filtration system, stainless steel materials filtration combined with molecular adsorption technologies
Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
Besides the common vacuum oil purifier's function of dewatering, degassing and eliminating particles, this machine can regenerate the seriously deteriorated oil by removing the polarity materials, such as the deep oxides, free carbon in the oil effectively. It can make the seriously deteriorated oil reach to the normal index like anti-oxides, acid-alkali water-solubility.
Efficient carbon fiber infrared 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.
Functions of live line work onsite, vacuum drying and vacuum oiling.
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.
Especially applied to vacuum oiling and drying (Hot Oil Circulation / on-site Drying) for power transmission equipments which are over 110KV.
Advanced dielectric Condenser devices and flow meter measuring the flow rate.
Low maintenance cost and time, simple operation and maintenances.
Based on different working needs, PLC, Fully enclosure, mobile trailer, explosion-proof, and other types can be designed.
