Oil Purification

Oil processing for transformers

Depending on the oil´s dielectric strength, oil purification for transformers is a process conducted through purification or circulation of oil.

Circulation of oil is a less demanding process than purification, if the oil is in a good condition it is only generally required to be transferred from a tank to a transformer by passing through the oil treatment machine.

On the other hand oil purification is a more demanding process because it needs to remove all impurities contained in the oil (water and solid materials) this in order to give the oil the desired quality to be applied to the transformer.

Tecnel Service can provide oil purifying services for volumes ranging from 200 litres to more than 50,000 litres.


Oil treatment services can be done in our workshop and onsite at customers (private transformers, companies and substations)
