Our Series ZYD-W Fully Enclosed Type Double Stage Insulating Oil Purifier provide you the best solution to on site transformer oil maintenance, the filtering of transformer oil is one of the least expensive, best known ways of preserving the life of the unit.
This series machine is designed by our experienced and skilled personnel that help clients perform oil processing on their power transformers working site especially at outside working fields, safely and efficiently. This is a fully enclosed type machine, all components such as pumps, motors, filters, tanks, valves, pipelines, controls, etc… are totally enclosed and protected by standard Metallic cover and doors enclosure. The equipment inside will be facilitated by a system of door locks installed at a perimeter of the enclosure. 
Vacuum oil filling, hot oil cleaning & circulating and transformer evacuating are also the great jobs that this machine can handle so as to keep all your oil filled equipment at optimum operating condition.
Features:
Double stage vacuum system: equipped with strong rotary vane Vacuum pump and booster roots pump.
Three-stage filter system or multi-stage filtration to remove various sizes of particles and impurities
Z-shape Heater to make the heating uniformity
Installing oil-level floating ball and double-infrared liquid level automatic controller to control the oil level
Foam sensor to avoid oil leaking
Temperature Controller to protect the machine operation and heaters
Suitable oil filtration machine for high voltage transformer
Large filtration area, high capacity of holding impurities
Two vacuum separator to increase separating size and time and ensure the drying degree and improve dielectric strength which is higher than 75 KV.
Doing online oil purification of substations over 110 KV.
Independent function of vacuum oil filling and drying.
Duplex stereo flash evaporation technology
Equipped with pressure protective system and interlocked protective system to connect oil pump, heater and liquid level controller. If there has any fault, this oil filter will be power off automatically.
Saving energy and time
Benefits of transformer Oil Filtration/Purifier
The conventional process of transformer oil exchange is time consuming, costly and not environmentally friendly.
Our mobile oil purification plants can regenerate the oil on site and in most cases while the transformer is online. This means there will be no production outages for you.
It will also be 30 to 60% cheaper to purify the transformer oil compared to exchanging the oil.
The process of oil purification not only restores the oil properties, but also cleans the inside of the transformer of all decay products, which would not happen if the oil was merely replaced.
Technical Parameters:
Note: 1. The dimension and weight will be changed with changing of technical specs.
2. All the specs can be customized according to client's requirements.
