  • Main characteristics

    With IGBT module power components and current inverting control technology, and parallel oscillating circuit is used.

    Wide frequency range from 1KHZ to 20KHZ, it is easy to match the machine according to the parts and heating desire.

    Due to the parallel oscillating structure, it is easy to get the best matching of the machine to get high heating efficiency and full power output of generator.

    Due to the high technologies of inverting control, soft and accurate switching control is realized to assure the high reliability and low repair of the machine.

    Small size , compared with SCR controlled induction heating machine, only 1/10 working space is needed, greatly reduce occupation space.

    High efficiency and energy saving, a high power factor and power efficiency within the scope of full power.

    With wide frequency range from 1-20KHZ automatic tracking ability, no need adjustment at scene.

    100% duty cycle , 24hours continuous working ability at maximum power.

    Constant output voltage or power control modes are alternative.

    Full display of output power, output frequency, output voltage and current.

    Simple operation, operate can be learned in a few minutes.

    Simple installation: connect the machine to 3phase 380VAC and cooling water only.

    Timer can be chosen to preset and adjusted the heating time, heating power, retaining time, retaining power respectively to control the heating curve and heating temperature.

    Advantages and applications of models with timer function

    Heating power, retaining power, heating time, retaining time can be preset and adjusted, this makes it possible to control the heating curve and heating temperature.

    It is suitable to use in the repeated heating or high speed heating of small parts.

    By presetting the timer and the power of the generator, retaining can be realized to a certain extent.

  • Main Applications

    Medium frequency induction heating machines are usually used in the penetration heating occasions, for example, Rod heating for forging

    Melting of almost all kinds of metals

    Heating of stators or rotors for fitting

    Heating of tube end for extrusion

    Heating of moulds

    Deep quenching of shafts and gears

    Tempering or preheating of weld joint and so on .
