Oil Purifier

Oil Purifier

During storage and transportation transformer oil comes in contact with air and gases, decreasing its dielectric strength by 20-30%. The air solved in the oil and in solid insulation reduces the dielectric strength of the whole transformer system and may cause electrical discharges.

Many producers have strict requirements in terms of vacuumizing transformer and presence of gases in transformer oil to improve reliability and extend the lifetime of the electrical insulation system. Particulate matter and moisture also have an advese effect on oil quality. Degassing and purification of insulation fluid before putting it into a transformer guarantees good electrical insulation and dissipation of heat from transformer parts.



CMM-05 general view


GlobeCore presents the CMM-0.5 oil degassing unit to engineering and servicing organizations involved with maintenance and repairs of small oil filled systems.

The СММ-0.5 oil purifier consists of a vacuum chamber, a heater, a fluid pump and a vacuum pump, as well as a filter section with replaceable cartridges. Equipment operates by heating the oil in vacuum to remove contaminants. Besides, the unit can transfer the oil and heat it.

GlobeCore has both stock oil purifiers and the ability to customize them. Processing rate, filters etc may be adjusted as requested by the customer. Stock models can be purchased directly form the company.

On customer request, our specialists can visit the site for commissioning and starting the unit and to train operators.

This approach allows us to effectively streamline our production, manufacture environmentally friendly products and keep our clients satisfied.



Oil is processed on an energized transformer. That is, the population of a whole city will not have to sit in the dark in the evening trying to iron their shirts with heavy books.
Up to 15 kV the transformer doesn’t even have to be de-energized to connect the processing system.


Complete restoration of oil.

The CMM-R features full oil regeneration cycle by one unit. The process includes filtration, degassing and restoration of chemical composition. There is no need anymore to use many complex devices: the CMM-R system does it all - and it’s easily controllable by only one operator.



Fuller’s earth, i.e. the sorbent used in this system, does not require disposal or refills. It is reactivated inside the system by the system! This is a world class innovation and a huge investment into a greener planet. This will even make it easier to attract the attention of investors, since environmentally friendly technologies is not only a modern world trend, but also often a requirement of many national programs and manufacturers, that is, your clients.



All out products are certified, reasonably priced and built to the highest quality standards. Not one product leaves the factor without rigorous trial at the factory’s testing facility.


With your own eyes.

Consider making a personal visit to the factory to see the first class technologies and also test your product samples. The results will be a pleasant surprise.


Global shipment.

We will deliver your CMM-R system anywhere in the world.
