GBR-Shaped (Tornado)
Engineered for precision and longevity, the GBR-Shaped (Tornado) delivers high thermal output with exceptional chemical stability across demanding environments.
Product Specification
GBR-Shaped (Tornado) SIC Element Capabilities
Diameter (Ø) Standard:
12–54 mm; Up to 75 mm available on request
Hot Zone Length (B max):
Depends on Ø; up to ~1,275 mm for Ø 54 mm
Overall Length (L max) :
Up to ~2,150 mm for Ø 54 mm; larger diameters can be longer
Resistance:
Up to 4 Ohm Custom design to requirements available
Operating Temperature:
In air: up to 1,600 °C
In various controlled atmospheres: rated similarly, although limits vary by gas Type: Can handle up to 1,650 °C in short-term exposures
Surface Loading (Hot Zone): Up to ~11 W/cm² (71 W/in²) at ~1,350 °C ~3 W/cm² at 1,600 °C; higher loadings possible with caution
Electrical Behavior: Resistance tolerance: ±20% at 1,000 °C
Exhibits negative temperature coefficient—resistance decreases as temperature rises
Increases in resistance over time: ~3% per 1,000 h at 1,400 °C, slower than standard-density elements
