Swift Heat is the leading manufacturer of Furnace Spiral Heaters in South Africa as well as a full range of heating elements, temperature sensors and controllers.

The lifespan of resistance heating element wire is dependent on a number of factors, the most important being:

  • Temperature cycling
  • Mechanical stress
  • Contamination
  • Alloy composition
  • Trace elements and impurities
  • Wire diameter
  • Surface condition
  • Atmosphere

These heaters can be fabricated with KANTHAL (Ferretic Alloys) and/or NICHROME (Austentic Alloys).  Ferretic Alloys offer higher operating temperatures but the Austentic Alloys (Nichrome) offer far greater mechanical strength over time.
