Mid frequency heater 

To improve the quality of welding, to prevent the pipe material lattice coarsening caused by delayed cracking the temperature of the base metal needs to be strictly controlled before welding. Our resistance heaters are designed to satisfy the pipe welding process needs. The heater using electromagnetic induction heating technology, with heating speed, high thermal efficiency, good controllability.

Technical features:

  • High quality components, advanced control mode, smooth running, high efficiency and small siz
  • Modular design, single key switch control, convenient maintenance and use
  • Focus on safety design, self-protection and reliable, to ensure the safe operation of equipment; strengthen the safety of workers.
