Design Features for Tempco Bolt Cartridge Heaters:

  • Hi-Density Construction
  • Conduit Box with Knockouts
  • Wooden Handle
  • High Temperature Lead Wires – 250°C (482°F)
  • Optional SJO Cord or Post Terminals
  • Optional Quick Disconnect Plugs

The higher wattage on our Hi-Density (swaged) Bolt Heaters means quicker heat-up time and minimum heat loss to the area surrounding the bolt. 

Tempco Bolt Heaters are sized for easy insertion into a hollow bolt. The rapid heating of the bolt expands it, allowing further tightening of the nut. The heater is then de-energized and removed. As the bolt cools, its contraction back to original size provides a tight fit.

Typical Applications:

  • Large Compressors
  • Turbines
  • Die Blocks
  • Large Cylinders
  • Engine Heads
  • Pressure Vessels
