Transformer oil services

Transformer oil treatment

Transformer oil treatment

FILOIL transformer oil treatment guarantees to lower the total gas volume, water content and to increase the break down voltage value to conform the requirements of IEC 60422.

All the equipment is mobile and works onsite of the transformers. All work can be carried out on and offline or online transformer. There is no need to take the transformer offline during oil processing.  Our units offer different oil flow and vacuum capacity thus always allowing us to offer the most appropriate solution for our customers.

Transformer oil regeneration

Transformer oil regeneration

REOIL transformer oil regeneration regenerates transformer oils into like new condition fulfilling the requirement of IEC 60422 standard.

Parameters indicating age of the oil inside the transformer such as Acidity, Tan Delta and Interfacial tension are significantly improved along with Break Down Voltage and water content. REOIL transformer oil regeneration is done onsite and can be performed on a live transformer.

Corrosive sulfur removal

Corrosive sulfur removal

REOIL transformer oil regeneration with corrosive sulfur removal removes corrosive sulfur compounds from transformer oils.

Sulfur, as well as elemental (free) sulfur (classified as S8), is removed so that treated transformer oil meets the IEC 62697-1 and IEC 62535 standards. Corrosive sulfur removal is done onsite and can be performed on a live transformer. During the sulfur removal process oil is also fully regenerated.
