Flexible tubular heater Hotflex

Bend your heating element yourself without tools!

The flexible tubular heater Hotflex is a flexible resistance which can be formed by hand in 3 dimensions, thus allowing a wide range of applications.

Easiest handling, simple assembly, optimal thermal features and the simple storage (the hotflex is supplied in straight condition) are outstanding product arguments.

This product is an excellent alternative to classic tubular heating elements, cast-in heating elements or cartridges.

Advantages

  • Easy installation with a uniform finish
  • Can be formed by hand
  • Stored in a straight condition to save storage space
  • No special installation tools required
  • Patented technology ensures industry leading heat transfer
  • Up to 75% sheath contact with round and square hotflex heaters when recommended groove geometry is followed
  • Rapid heat-up times
  • Minimal temperature difference between heater sheath and heated tool
  • 3-dimensional groove geometry possible
  • Industry’s smallest bending radius
  • Hotflex’s flexibility enables heat to be located where it is needed; an improvement over rigid cartridge heaters
  • Reduced energy costs: tool mass can be reduced

Depending on the number of bends the hotflex length can increase.
