Applicable scope：
1.For maintenance of large scale power substation transformers, rapid and deep treatment of new transformer oil, imported insulation oil. As well as vacuum filtering and purifying of mutual inductor oil, capacitor oil, refrigerator oil.
2.Especially suitable for purifying of large scale power transmission units higher than 110KV and transformers of main state grid.
3.It is widely used in power plants, power stations, power companies, metallurgy, petrifaction, machinery, transportation, railways ect. industries, especially at plateau area higher than 500 meters sea level.
Advantages:
1.outdoor use with roof,close/open ventilation window,skid basc mounted,enough lifting hook
2.Besides the features of ZJB series vacuum purifier, it’s added roots booster pump system, the secondary high vacuum air extracting system for rapidly removal of gas and moisture. It avoids the weakness that displacement sharp declines while the vacuum purifier working at a high vacuum degree. Performance of one cycle of processing is equivalent to two units common vacuum purifier.
3.High extraction speed double vacuuming systems which is able to utmostly enhance the vacuum environment of internal vacuum tank to make high vacuum. Ultimate vacuum ≤5Pa, working vacuum ≤35Pa, keep the oil temperature during processing to fulfil the vacuuming requirement of installation or maintenance site, highly reduced oil processing period.
4.After filtration, the di-electric strength and flash point is higher, after one cycle of filtration, breakdown voltage increases 3-5kv, effectively avoid oil ageing resulted from repeatedly heating.
5.High performance configuration: advanced infrared liquid level control system, pressure protection system and oil pump interlock controlled to ensure long time and safely operation.
6.The unit able to maintain energized transformers and long time online operation, fitted automatic de-foam facility for working in plateau area, it can be automatically working without people’s supervision.
High precision and intelligent degas system is able to remove all sorts of gas from oil rapidly, avoid the existing of hydrogen, ethyne, ensure the content of ethyne of oil after treated to “zero”.
7.One machine two function, both vacuum purifier and vacuum unit, it can be used for vacuum filling for insulation units, it is able to reduce transformer installation and maintenance time, the product is at the leading position of this field.

Why do we choose oil purifier machine?
After a period of operation, owing to its expose to oxygen and mixed with water, copper and iron and other foreign materials and high working temperature acceleration , transformer oil will oxidize and lose its original property and cannot be used effectively again. So oil purifier machines can efficiently remove water, dirt, gases and other foreign impurities from oil, such as turbine oil, lubricating oil, engine oil, hydraulic oil, compression oil, mechanical oil, quenching oil, heat conducting oil, gear oil etc; so as to maintain its lubricating and insulating property, then to reduce components wear, and cut down oil expenses.
