Our metal electric heating resistances
Metal electric heating resistances are made from a resistive nickel-chromium (NiCr) or iron-chromium-aluminium (FeCrAl) strip or wire.
The maximum operating temperatures are:
- 1250 °C for the NiCr alloy
- 1350 °C for the FeCrAl alloy
Our main creations are:
- Coiled wire resistances
- Hairpin wire or strip resistances
- Heating glow plugs
Coiled wire resistance
The resistance consists of one or more coils or “rays” connected by bridges.
At each end, the outputs may be:
- Single wire
- Twisted double or triple wire
- Rod, with or without end thread
The areas of application are diverse:
- Thermal treatment furnaces
- Ovens
- Aluminium smelting/holding furnaces
- Indirect bath heating
- Glass furnaces
- Ceramic and porcelain furnaces
- Incinerator furnaces. . .
Hairpin resistances can be used with various types of support:
- Fitted onto smooth or threaded ceramic tubes
- Bracket-mounted
- Inserted into ceramic parts with grooves
- Partially embedded into concrete or fibrous material
We can make the ceramic holders suited to your needs, along with more elaborate assemblies.
Contact us and/or request the technical data sheets for our metal heating resistances.
Hairpin wire or strip resistances
The resistance consists of a series of waves. It is fitted at each end with outputs for cold connections
The areas of application for hairpin resistances are also varied:
- Thermal treatment furnaces
- Glass furnaces
- Continuous annealing lines
- Indirect bath heating
- Galvanising furnaces. . .
