Industrial oil processing since 1996

Engineered to outlast the asset it serves

Ekofluid designs and manufactures transformer oil treatment, regeneration, and vacuum processing systems, plus bespoke installations for X-ray, defense, medical, and refining applications. The company also operates an on-site service fleet, running regeneration and treatment campaigns on live transformers. Built in-house.

Engineered to outlast the asset it serves

Transformer oil expertise

Ekofluid builds the equipment and runs the services that keep transformer oil in specification. FILOIL for treatment, REOIL for regeneration, on-site service crews for both. Mineral oil and esters, distribution transformers to power transformers.

Ekofluid designs and manufactures transformer oil treatment, regeneration, purification, and vacuum processing systems, plus bespoke installations for X-ray, defense, medical, and refining applications. Every platform is engineered, built, and tested in-house in Levice for long-term reliability across mineral and ester oils.

FILOIL

Transformer oil treatment

The platform by which transformer oil treatment is measured. Mineral oil, 1 500 to 24 000 l/h, stationary or mobile.

FILOIL est.

Ester oil treatment

The FILOIL platform, modified for ester chemistry. Natural and synthetic esters, treated to the same dielectric standard as mineral oil.

On-site services

On-site, on a live transformer

Ekofluid operates its own service fleet, running REOIL and FILOIL equipment at the customer's substation. Most services are performed while the transformer remains energized — no outage, no downtime, no transport of oil off-site.

Proven worldwide

Thirty years. Seventy countries. Five hundred systems.

Ekofluid has delivered transformer oil treatment and regeneration systems to utilities, OEMs, and service providers across six continents since 1996. The numbers below are the simplest measure of what that experience has produced.
