Middle frequency generators

Mounting, dismounting, pre-heating. All of that is possible with the BETEX MF Quick-Heaters

Thanks to mid-frequency technology, energy is transferred to the workpiece effectively, heating it easily and fast. The MF Quick-Heater consists of a generator with a fixed or flexible inductor. The compact dimensions make it easy to move. MF Quick-Heaters save time because they can be used quickly (fewer actions) and heat faster than conventional methods. One of the major advantages of this type of induction heater is that they are not limited to cylindrical shaped components: flexible inductors can be wrapped around any size or shape. Since the frequency is relatively high, the penetration depth of the magnetic field is not too large, so that only the outer layer of the workpiece is heated. This principle makes heating using medium-frequency particularly suitable for dismantling purposes, such as removing bearing rings from shafts.
