GlobeCore’s oil regeneration process restores used oils to a condition close to new oil. This process makes it possible to fill transformers with oil that would otherwise have been disposed of. The oil can be used in the transformer without replacement throughout its entire service life.
GlobeCore’s CMM-R systems are designed to extend the transformer’s lifespan by restoring the dielectric strength and chemical composition of dielectric insulating oil.
In the oil regeneration process, oil degradation products and acidic compounds are removed, the oil becomes clear, oxidation resistance improves, while its gas solubility is reduced.

GlobeCore manufactures oil regeneration systems for both transformer manufacturers and transformer service providers.
GlobeCore units are loaded with a sorbent that captures all oil decomposition products.
GlobeCore regeneration systems can use the same sorbent for up to 3 years before the first replacement. No more need for consumables and costly labor related to the replacement of exhausted sorbent at the job site.
Regeneration systems can be combined with degassing units or purchased as stand-alone systems.
GlobeCore regeneration systems can be used in combination with your existing degassing or drying unit.
Each GlobeCore unit can be customized and includes a number of options:
- Extra vacuum pump assembly for transformer vacuuming;
- Mounted on a trailer or semi-trailer;
- Moisture meters at the inlet and/or outlet of the oil stream;
- Remote control and process monitoring via smartphone or PC;
- Climate-controlled operator workroom.
Application:
How is sludge removed from transformer windings?
Sludge is removed from transformer windings by circulating oil through the transformer at a temperature above the aniline point – the temperature at which sludge begins to dissolve in the oil. This temperature is usually around 80°C.
Sludge removal is performed simultaneously with oil regeneration. Only fresh or regenerated oil should be used for sludge removal.
Transformer winding cleaning can be performed with the transformer either energized or de-energized. The cleaning process requires 30 to 60 passes through the regeneration unit.
When the transformer is de-energized, the efficiency of sludge dissolution decreases due to the absence of winding vibrations. As a result, the cleaning process takes longer.
