Company history
Depom Induction was founded in 1996 by the merger of Germany’s Fritz Düsseldorf Induktionserw?rmung and
Norway’s ELVA Induksjon. The roots, however, go back to the 1950 s.
The story of EFD Induction go back to the launch in 1950 of a universal induction hardening machine by the
German company, Induktionserw?rmung Fritz Düsseldorf GmbH (FDF).
While FDF was expanding in the 1970s, an induction revolution was taking place in Norway, where engineers had
figured out how to transistorize frequency converters for induction heating.
In 1981, three of those engineers founded ELVA Induksjon a.s. In 1983, they unveiled the Minac range of mobile
converters. Workpieces no longer had to be brought at great cost to a stationary induction heater—the heater
could now go to the workpiece.
In 1991, the managing directors of FDF and ELVA met by chance. They talked… and speculated. FDF was strong in
stationary induction hardening machines. ELVA was the agile innovator with a track record in finding new
applications for induction heating. What if the two companies got together?
In January 1996, FDF and ELVA merged to create EFD Induction. And the rest is, as they say, history.
Today, EFD Induction is one of the world s largest suppliers of induction heating solutions for industry .
The corporate headquarter is in Skien, Norway.
