Manufactured with helical coiled resistive wires with distances between spiral and spiral 2 and 3 times the diameter of the wire.


  • Heaters without electrical insulation between the heating element (resistive wire) and the medium in which they operate.
  • High transfer factor. Low losses between the heat source and the material to be heated.
  • Heat transfer mainly by radiation and convection.
  • Minimum time between ignition and the beginning of heat release.
  • High operating temperatures normally reach 1100 ° C.


  • Ceramic ovens.
  • Tempered and figured glass.
  • Industrial ovens.
  • Domestic water heaters.
