Flexible Tubular Heater Manufacturer

Standard Lead Times


MPI Morheat Flexible Tubular Heaters are completely flexible and may be shaped around pipes, along platen paths, and into other challenging shapes that require precise heating. We have several options for terminations and temperature control to meet your needs and they are excellent replacements for traditional tubular heaters and other electric heating elements and heating systems, which are not flexible. 

Standard Features
  • Easy installation with a uniform finish
  • Can be formed by hand
  • Store in a straight condition to save storage space
  • No special installation tools required
  • Patented technology ensure industry leading heat transfer 
  • Up to 75% sheath contact with round and square flexible tubular 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
  • MPI’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
