Inductive heating was discovered by Michael Faraday in 1881 and for a long time was regarded as an undesirable side effect in transformer construction. Nowadays inductive heating is used for all types of metal heating in many areas of industry and is in use throughout the world.

The principle of inductive heating is based on eddy currents which are induced in the workpiece and heat this within a very short time by continuous polarity reversal.

A high eddy current frequency and the necessary power are required for this.

Mobile and stationary frequency inverters having a power range of 5-2000 kW and frequencies of 3-500 kHz are available as installations.

Inductive heating is not only cost-saving but also has exceptionally high speed, precision and reproducibility.

From the environmental point of view, inductive heating also offers substantial advantages compared with heating using fossil fuels or compared with resistance heating.
