ProHeat™ 35 Induction Heat Systems Solve Ongoing Preheating & Stress Relieving Problems

This simple and cost-effective heating process can deliver fast and consistent heat for:

  • Welding fabrication and construction;
  • Preheating of welds;
  • Post-weld heat treatment;
  • Coating removal; and
  • Shrink fit applications

Applications that would typically require hours to heat can be done in minutes utilizing induction heating.

In addition to the simplicity and efficiency, the ProHeat 35 induction heating system solves many key issues in today’s environment:

  • Does not produce the exposure to burns associated with open flames and electrical resistance wires (only the work part becomes hot)
  • No significant expense of fuel gases.
  • Produces fewer fumes than flame heating.
  • Produces less particulate from overheated insulation caused by high temperature electrical wires and ceramic pads.

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.

Preheat up to 400°F (204°)

Applications
- On-Shore Transmission Pipelines
- Off-Shore Transmission Pipelines (Barge)
- Shipbuilding
- Mining

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.

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.

The ProHeat 35 Liquid-Cooled Induction Heating System provides a highly versatile tool for preheating, stress relieving, hydrogen bake out, and post weld heat treat in a variety of pipe diameters and even flat plate.

  • In general, shorter cables are used from smaller diameter pipe and are easier to handle and set-up. Longer cables are used for larger diameter pipe or small pressure vessels and tanks.
  • Great for preheat application on geometrics that prevent use of air-cooled blankets.

Preheat, hydrogen bake-out and stress relieving up to 1450°F (788°)

Applications
- Pipe Fabrication Shops
- Field Construction of Power and Process Piping
- Shrink Fit
- Shipbuilding
- Mining

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 is achieved using flexible heating cables combined with user-friendly insulation blankets.

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.

The ProHeat 35 Induction Heating System with the Rolling Inductor is a simple and cost-effective heating process that can solve many preheating problems related to heating moving parts and delivers fast, consistent heat.

Preheat moving parts up to 600°F (315°)

Applications
- Process Piping
- Refinery
- Petrochemical
- Power Piping
- Pressure Vessels
- Plate

Maximum productivity with easy setup, quick time to temperature, and continuous heating increases productivity while reducing consumable costs and labor expenses.

Improved safety by eliminating open flames reducing burn and explosive gas hazards. Direct heat transfer results in cooler shop environment that reduces operator fatigue and improves work conditions.

Flexibile, compact and portable to fit a wide range of preheating applications on pipe, plate and other moving parts.

Optimal consistency and quality
Designed to evenly distribute heat into the work piece, eliminating the inconsistencies and quality issues associated with open-flame-torch heating methods.

Travel Detect system (optional) helps to ensure proper heating by folding back or shutting off output if limited or no movement is detected.
