The BETEX MF Quick-Heaters leverage medium-frequency technology to provide an efficient solution for the mounting, dismounting, and preheating of metal components. This technology ensures that energy is effectively transferred to the workpiece, enabling it to be heated quickly and easily. The core of the system is a generator equipped with either a fixed or flexible inductor, designed to accommodate the specific needs of different applications. Its compact size enhances its portability, making it a versatile tool for various settings.

One of the key benefits of the BETEX MF Quick-Heaters is their ability to save time. They are designed for rapid deployment, requiring fewer preparatory actions, and achieve faster heating times compared to traditional methods. This efficiency is further complemented by their low power consumption, which translates to significant energy savings. Unlike conventional heaters, the BETEX MF Quick-Heaters are not restricted to cylindrical components; the flexible inductors can be adjusted to fit any size or shape, expanding their application range.

Middle Frequency Quick Heater – BETEX

The heaters offer several advantages, including their suitability for a wide range of materials such as steel, cast iron, stainless steel, and titanium. They feature temperature and/or time-controlled heating, with dual temperature measurement for precise ΔT monitoring. With low connection power requirements and adjustable generator output ranging from 2.5 to 22/44 kW, these heaters are both easy to use and highly flexible. They are ideal for both production and maintenance tasks, eliminating risks of residual magnetism, fire hazards from open flames, and nuisances like noise, fumes, or smoke. Additionally, their air-cooled design negates the need for water cooling.

The BETEX MF Quick-Heaters are particularly beneficial for heating ferromagnetic workpieces, including bearings, labyrinth seals, bearing rings, housings, gear wheels, rollers, tubes, bushings, couplings, train wheels, extruders, and stator housings. Their operating principle involves rectifying three-phase voltage, which is then converted into an AC voltage with a frequency between 10 and 25 kHz. This high-frequency AC voltage is applied to the workpiece via a resonance capacitor and an inductor, focusing the heating on the outer layer of the workpiece and making it especially suitable for dismantling tasks.

For specialized applications, testing with client-provided components can be conducted to ensure the heater’s suitability and performance. The use of simulation programs and a comprehensive database of examples aids in providing optimal solutions, ensuring measurable savings by allowing the reuse of parts without damage. The ΔT monitoring feature further enhances control during heating processes, ensuring even heat distribution and preventing material stress, which is crucial for stress-free mounting and dismounting operations.
