The RF generator can be optimally adapted to different system environments due to different options.

Remote control unit

The remote control unit provides the same scope of functions as the control panel on the generator. This means you can operate the generator directly in the application environment while simultaneously monitoring the heating process.


Using a matchbox, known as an external circuit, the load (induction coil + workpiece) can be optimally adapted to the RF generator so that this can always output the maximum power. Various matchboxes are available for a variety of applications.

The choice of suitable system components means that the RF generator can be optimally adjusted to the required application.

The inductor geometry is specifically adjusted for the required heating process (ring, line or mold inductor).
Pyrometers are used for non-contact temperature measurements on surfaces up to 3632 °F. A coupled program controller enables temperature profiles to be followed precisely.
Process cooler
The process cooler ensures reliable dissipation of process heat. Versions are available for various power ranges.
