The ProHeat 35


Induction Heating System 

  • Specifically designed for preheating applications up to 400° F (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.  

Proheat 35 Power Source
The ProHeat 35 induction power source is equipped with a built-in temperature controller allowing for manual or temperature-based programming with an easy-to-learn operator interface.
Contact Thermocouple Sensor (Probe)
Contact thermocouple sensor installed between the insulation and the part being heated. The contact thermocouple sensor can be used in preheat applications up to 500 degrees Fahrenheit (260°C).
Induction Heating Blankets
Miller’s patented flexible induction blanket is the newest innovation in preheat technology from a leader in the welding industry. The flexible, lightweight induction heating blankets come in a variety of sizes and are capable of preheat temperatures up to 400° F (204° C). See Lit. Index No. IN/3.0 for additional information on temperature rating and duty cycle.

The blankets easily conform to circular and flat parts and install in a matter of seconds.
Output Connector
System Configurations

The ProHeat 35 Induction Power Source is designed with two output connectors for either air-cooled blankets or liquid-cooled cables. This capability requires the use of same size air cooled blankets or in the case of liquid-cooled systems, the applications must be the same (same size pipe, same program and same coil). The Cable Identification System is able to detect which type of cables are attached and configures the maximum output for the power source.
Contact Thermocouple Securing Band
Positions the contact thermocouple sensor in the heating zone and retains it in place, ensuring consistent controlled heating.
Remote Contactor Control
Remotely start and stop the heating process with this wired rocker switch remote. Includes a 25-foot (7.6 m) cable.
RHC-14 Remote Hand Control
Remotely adjust the heat output of the system in manual mode as well as start and stop the heating process.

Available Sizes:
20 ft. (6 m)
100 ft. (30.5 m)
Replacement Kevlar Sleeve
Each blanket is supplied with one replaceable Kevlar sleeve which provides added protection against abrasion, cuts and tears, extending blanket life. Replacement sleeves are available for all blanket sizes.
Output Extension Cables
Output extension cables are available in 25 and 50 ft (7.6 and 15.2 m) lengths and provide interconnection between the power source and flexible induction heating blanket. This product includes durable twist lock connectors for attachment to the induction blanket. The heat treating power source connection is made using an insulated twistlock connector which also identifies the type of heating device to the power source controller (air-cooled or liquid-cooled system).
Thermocouple Extension
A shielded, 25-foot (7.6 m) thermocouple extension for connecting between the contact thermocouple sensor and the ProHeat™ 35 power source.
Series Cable Adapter
The series cable adapter is used to combine two blankets in series. This enables one power source and one output cable to be used to create extra heating area using two induction heating blankets.
