INDUCTION HEATERS BETEX MF Quick-Heaters – medium-frequency technology Mounting, dismounting and preheating of metal components Fast and/or controlled heating with ΔT Thanks to medium-frequency technology, energy is transferred to the workpiece effectively, so it is heated easily and quickly. The BETEX MF Quick-Heater consists of a generator with a fixed or flexible inductor. Its compact dimensions make it easy to move. BETEX MF Quick-Heaters result in time savings as they can be deployed very rapidly (fewer actions) and heat faster than conventional methods. Energy use is much more efficient thanks to its lower power consumption. One of the major advantages of this type of induction heater is that they are not limited to components with a cylindrical shape: flexible inductors can be wound around any size or shape. Advantages of BETEX MF Quick-Heaters or mounting, dismounting and preheating 3 F Suitable for steel, cast iron, stainless steel and titanium 3 Temperature and/or time controlled heating 3 Double temperature measurement (ΔT monitoring) 3 Low connection power (32/63 Amp) 3 Generators are adjustable from 2.5 to 22/44 kW 3 Easy to use and flexible 3 Suitable for production and maintenance applications 3 No residual magnetism 3 No fire hazard due to open flames 3 No noise, fumes or smoke nuisance 3 Air-cooled: no water cooling needed 3 Because the work is carried out damage-free, expensive components can be reused 3 The BETEX MF Quick-Heater This heater consists of a generator and one or more inductors. The generator is designed for the connection of inductors used for heating ferromagnetic workpieces. Suitable materials include iron, steel, stainless steel, titanium and certain bronze alloys. The maximum capacity workpieces can be subjected to is 22 kW or 44 kW, depending on the type of heater. Operating principle The three-phase voltage is rectified and smoothed. This rectified voltage is then converted by means of an inverter into an AC voltage with a frequency between 10 and 25 kHz. The power is then applied to the workpiece magnetically via a ‘resonance capacitor’ using an inductor (coil). To be used for • Bearings • Labyrinth seals • Bearing rings • Bearing housings • Gear wheels • Rollers • Tubes • Bushings • Couplings • Train wheels/train wheel tyres • Extruders • Stator housings 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 removi

Flexible inductors Flexible inductors are a multifunctional solution for various shapes or sizes. They can be used in or around a workpiece. Heating a bore for bearing or shaft mounting Heating a coupling for dismounting Heating bearing rings for dismounting Heating labyrinth rings for dismounting Fixed inductors Fixed inductors are used for serial work. Testing For special applications, we can carry out tests in advance with components that the client provides for this purpose. If necessary, we can supply a customised application. For standard applications, we have a large database with examples....
