  • Such sectional heating elements are used primarily in electric radiators, which have an electrical heating element.
  • Such radiators are composed of individual members, which are connected by special threaded connectors with seals. This connection is called nipples. Since there is a relatively high risk of leakage, all radiators must be extensively tested for leaks using compressed air or water.
  • the radiators are then filled with a thermal oil or a mixture of water and glycol as carrier media.
  • an electrical heating element is screwed into the nippled radiator in the lower right corner and provided with an electronic control.

  • an opening is provided on a transverse section, which is usually directed down to the ground.
  • a heating element can be used subsequently to the assembly of the radiator from the individual members. Furthermore, this opening also allows replacement of any defective electrical heating elements.
  • the sectional heating element can be configured in a simple manner to an electric heater.
  • the radiator elements are the same design and cast or formed from an extruded profile.
  • the radiator members are made of a metal, preferably aluminum. They basically have an elongated shape with the longitudinal section and the two shorter transverse sections. To improve the Heat radiation and optical reasons can be arranged with great variety of shapes ribs and cover plates. In cast radiator members, these are preferably formed in one piece. Alternatively, these can also be manufactured as a particularly favorable extruded profile.
