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
- Alloy composition
- Trace elements and impurities
- Wire diameter
- Surface condition
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.
