History
The effect of induction heating was discovered by Michael Faraday
in 1881 and was seen for a long time as a negative side-effect in the
use of transformers.
The EFD group was founded in 1996 by a merger of ELVA Induksjon a.s.
from Norway (established in 1981) and by Fritz Düsseldorf Freiburg GmbH
Germany (established in 1950).
The roots of the EFD group are going back to 1950 when the German
company Fritz Düsseldorf GmbH (FDF) launched its first stationary
induction hardening machine to the German market.
While FDF expanded during the 1970ies, in Norway a pioneering and
epoch-making development became its readiness for marketing. Engineers
developed how to design transistorized frequency converter for
induction heating.
In 1981, three Norwegian engineers founded ELVA Induksjon. The new
company had only nine employees. But it also had its MINAC range of
mobile converters, which was successfully launched in 1983. Workpieces
no longer had to be brought at great cost to a stationary induction
heater - the heater could now go to the piece
In 1991, the managing directors of FDF and ELVA met at a trade
exhibition. They recognized the potential of its counterpart and the
possibilities which could develop by a merger of the two companies.
During the years between 1991 and 1996 ELVA Induksjon expanded and
established a sales and service organisation network all over Europe,
and also in Austria.
After ABB has spun off its induction heating division and shut down the
production of valve generators in Vienna, several employees launched
its own business. This company became short time later the Austrian
subsidiary of ELVA Induksjon, which is successfully running its
business in sales and service in the Austrian market and many of the
surrounding countries.
In January 1996, FDF and ELVA merged and founded EFD Induction.
By the continuous expansion course on the sector of induction companies
the structure of EFD grew and adapted to the market requirements:
