Vacuum Transformer Oil Treatment Price

It is widely used in the oil purification treatment and vacuum hot oil circulation drying in the installation and maintenance of various large transformer equipment.. Not only use in Insulating oil purification treatment in 110KV-550KV transformer,but also applies to high-grade new oil, the high depth of processing imported oil. Compared with the single-stage vacuum purifier machine, the machine increases the Roots pump pressurization system,secondary high vacuum separation systems and three-dimensional flash rapid evaporation system , it can quickly dewater, degas, and remove the acetylene, acid value and free carbon , The transformer oil limit Breakdown voltage value will be higher after treated,It 's not only used for oil purifier but also as a separate vacuum source which have the function of vacuum drying and oil injection for transformer equipment

The double stage Transformer oil filtration machine was designed according to decompression separation, precise filtration, Spiral spray atomization separation technology, molecular adsorption ,vacuum drying principle. The treated oil can meet the standard of the national standard.

3.Flow Chart
The oil to be treated passes through a strainer and enters the heater for heating, the heated oil will go through the semi precision filtration and arrived at the Spiral spray atomization separation system, The insulating oil turns into a coarse mist and falls onto the reaction tower to enter the vacuum separation chamber. The moisture begins to evaporate and the oil mist forms a three-dimensional, multi-layer evaporation structure in the tank, which can be purified through a short-term cycle. After dewater, degas, and impurity ,acid removal,the treated oil will go through the precision filtration to achieved the purifier circulation purpose.The Water vapor molecules and the hot air are separate from the vacuum separation chamber enters the condenser ,Most of the water vapor is condensed into water and stored in a water tank. The hot air in the oil is cooled and discharged by a vacuum pump.

Q1.What is the usage of vacuum oil purifier?

It can remove 100% free water and 99.9% dissolved water, 100% free gas and 98% dissolved gas, impurities, and prolonged the machine's life.

Q2.Does your process use chemicals or additives?

No, it is pure -physical technology.

Q3.What is consumable?

There is no consumable in oil purifier except filters.

Q4.How often do clients need to change filters

It lasts for at least 3,000hours .But it depends on oil cleanness.

Q5.What is your material of your machine?

Carbon steel or Stainless steel (Standard type is SUS304, it can be customized according to your request)

Q6. Any any of the products be customized?

Yes, we can customize the color, industrial power and your logo on machine. On the other hand, if you need the brand ingredients on the machine, you can have the choice on the imported pumps electrical ( electrical elements , PLC, touch screen LCD controller)
