Eco-friendly transformers - for industry and utilities

A transformer, adapted specifically for industry and utilities, has an estimated lifespan of 30-40 years. It is likely to last even longer. It is therefore important that you invest in a transformer that meets tomorrow's requirements now. This is one of the reasons why we constantly work to exceed legal requirements and why we regularly introduce new products that have a lower environmental impact than existing products on the market.

With Unitrafo, you get experience, knowledge and vision for the future. We have been specializing in transformers, for use in industry and utilities, for over 30 years and work closely with many of the leading manufacturers in Europe. Together we develop products for the Nordic climate and environment, so you can always be sure to get a product that suits your needs. Contact us at and you will receive personalized service and pleasant treatment - from start to finish.

We supply transformers from 10 VA up to about 600 MVA and for most applications, ranging from smaller isolating transformers to larger power transformers for industry and energy companies. See our product page if you want to know more.

Unitrafo follows the EU rules which entered into force on July 1, 2021, and has a product line where all products meet the requirements for Eco design - Tier 2. We have also introduced new products that exceed these requirements.
Today we market three types: MiljöEko2^®- suitable for medium loads, EnvironmentPlus^® suitable for medium to high loads and EnvironmentMax^®, with amorphous core, when you have high loss rating, varying loads but low average load. Common to all types are low total power losses, resulting in lower environmental impact and superior lifetime economy.

ATTENTION! The picture shows a cast resin insulated transformer, but of course the Ecodesign Directive also applies oil-insulated distribution transformers and power transformers.
