The ProHeat 35 Air-Cooled Induction Heating System is specifically designed for preheating applications up to 400° Fahrenheit (204°C).

  • Air-cooled blankets are available for pipe diameters from 8-60 inches (20-152 cm) or in the case of plate, the lengths are 41-205 (1-5.2 m).

  • The blankets easily conform to circular and flat parts and install in a matter of seconds.

  • Manufactured from durable high-temperature materials, flexible induction blankets are designed to withstand the tough conditions in both industrial and construction applications.

Improved working environment is created during welding. Welders are not exposed to open flame, explosive gases and hot elements associated with fuel gas heating and resistance heating. 


Easy set-up with flexibility to fit a variety of pipe diameters and plate lengths.

On-board temperature control provides for manual or temperature-based programming in a simple-to-learn operator interface.

Uniform heating is maintained along and through the heat zone by using induction to heat within the material. The surface of the part is not marred by localized conducted heat at higher than specified temperatures.

Time-to-temperature is faster than conventional processes due to the method of applying heat, reducing cycle time.
