Main characteristics:

1. IGBT module and inverting technologies, better performance ,higher reliability and lower maintenance cost;
2. 100% duty cycle, continuous working is allowed at maximum power output;
3. constant current or constant power status can be selected accordingly to achieve higher heating efficiency;
4. display of heating power and heating current and oscillating frequency;
5. multi-display functions, with displays of over current, over voltage, water failure, phase failure and unfit lad and so on, machine can be protected from destroys and machines can be repaired easily.
6. simple to install, installation can be donne by unprofesstional person very easily, connection water and power can be finished in a few minutes.
7. light weight, small size.
8. different shape and size of induction coil can be changed easily to heat different parts.
9. advantages of the model with timer: the power and the operating time of the heating period and retain period can be preset respectively, to realize a simple heating curve, this model is suggested to use for batch production to improve the repeatability.
10. the separated models are designed to fit the dirty surroundings, the generator can be put in a clean space to increase the reliability; with the small size and light weight of the separated transformer, it is conveient to use in the production line and easily assembled inside the machinery or moved mechanism.

Main application:

1. heat treatment of gear and shaft  2. heating of stainless steel parts in kitchen wares factories for shaping.  3. heating of rods for shaping  4.heating of rotors or stators for fitting.  Etc.
