Custom Made Induction Heaters
Low frequency induction heaters
Designs and builds customized induction heaters for serial heating of parts, such as bearings, sprockets, gears, bushings, rings and aluminium housings of E-motors. If fast heating and accurate temperatures are important, these Low frequency "Specials" offer solid solutions.
Spectacular heating times: 15 to 300 seconds
Temperatures up to 480°C
Suitable for the most popular metals and alloys.
Automatic, semi-automatic or manually operated.
For serial heating or heating of non-standard shapes
Mid frequency induction heaters
Mounting and dismounting solutions with Mid frequency heaters.
By applying medium-frequency technology, effective energy transfer takes place to the workpiece, which makes it heat up quickly and easily. The Quick-Heater consists of a generator with a fixed or flexible inductor. Inductors are custom made to fit special applications. Thanks to the double temperature measurement (Delta-T) perfect controlled heating is possible, fast or slow, depending on the application.
