Company history

w.frei ag was founded by Walter Frei Senior in Jona in 1967, where the company is still based. Having started out repairing and overhauling electrical machines, activities were then expanded to include control systems for drives and electrotechnical devices.

On the back of some major orders, a decision was made to bring the manufacture of chokes, coils and cables in-house. The new “Production” department ensured efficient, high-quality manufacturing. The Geberit Tool Service Centre, where electrofusion units and other devices are repaired, came into being later as a third pillar for w.frei ag. The first of these devices was developed and manufactured more than 40 years ago by Walter Frei Senior at Walter Frei AG.
