With continuous investments in research and development, FRIEM is leader in Diode, Thyristor or IGBT type High Power Converters, applying the most advanced technologies and electronics.

Founded in 1950 to design and manufacture High Power Converters, FRIEM continued to develop its know-how in energy conversion for Industrial, Traction and Renewable Energies applications. In 1956 FRIEM produced and installed its first 50kA Rectifier Unit for application in Chlor-Alkali industry. At the absolute forefront in technology, in the early 60’s FRIEM was able to manufacture units rated up to 110kA and to design the first high current Thyristor Rectfier. Service continuity required by the Electrochemical Industry oriented FRIEM’s design towards absolute reliability: quality, safety, latest international standards have always been the base for the design and development of our Equipment.

This experience and know-how were applied in the early 70’s when FRIEM started the production of Rectifier Units for traction application. With the support of its Partners, FRIEM provides complete Substations Systems with all the main equipment and services.

In 1984 FRIEM was able to design and start-up its first Power Supply for a PolySilicon CVD Reactor. Nowadays FRIEM has hundred of units in service all over the World supplying  all the different types of CVD Reactors.

In 2009 FRIEM started the production of the ReCon Line, a complete line of Inverters for the Renewable Energies, becoming one of the main manufacturer in Italy and in the World.

In order to serve our customers with a wider range of products and solutions, FRIEM has started partnerships and investments with expert Electrotechnical Companies. This strategy gives FRIEM an even stronger Local presence, with offices, workshops and representatives in more than 20 Countries all over the World.
