25 KW high-frequency induction heater that provides high efficiency, low energy consumption and high output power

    Working with metals and their processing often requires that there is a constant, stable and reliable working temperature around so that they can be treated. Stable high temperatures are usually provided by high-frequency induction heaters, which allow the operator to use targeted heating and quickly and efficiently heat the area required.

    When it comes to inductive heating, the  LH-25A High-Frequency Induction Heater is among the best. It adopts the latest MOSPET and IGBT power units and the latest frequency control methods and techniques, and provides high efficiency, low energy consumption and very high output power. Through this, it achieves efficient and quick heating of any targeted area, and is highly useful when heating metals.

    It has a 100% load design, which means that it can work 24 hours without stopping. Should there be a problem, there is an infrared temperature detector which alarms the operator if the machine overheats, and it also allows easier temperature control and simplifies manual operation. 

Main Features

1. Power consumption is half of traditional electron tube high frequency induction heating equipments under same conditions

2. Heating, insulating, and cooling time can be adjusted separately. Benefit for a batch of workpieces and fast heating.

3. Multiple status display of overflow, overvoltage, low water, phase failure and load malfunction. Provides higher reliability and sustainability

4. Select power supply according to the power and frequency. The higher the frequency, the shallower the heating depth, and the lower the frequency, the better the diathermancy.
