Trafox is a brand of Muuntosähkö Oy, under which we develop, manufacture and customise high-quality transformers, chokes, filters and Trafox Superintend® monitoring devices. Our products are used in various applications from heavy industry to health care.

Thanks to our seventy years of experience, we understand our customers’ individual and field-specific requirements and we are able to provide them with solutions that create true added value. The starting point for our product development is the diverse Trafox solutions, which meet both international standard requirements and customer-specific needs.

The company was founded in 1947, and while it still has its roots deep in the Finnish soil, it also operates in the international market. Besides Finland, we have customers in other northern European countries as well as in Central Europe, Asia and the United States. Our headquarters are located in Helsinki, with production facilities in Helsinki and Joensuu (Finland), Viljandi (Estonia) and Suzhou (China).
