Mighty Tuff Band Heaters

Rugged construction along with high temperature and high watt density capabilities allow the Mighty-Tuff Band Heater to surpass all other band heaters in providing the ever increasing temperatures required for processing today's high tech materials. The advanced design and thin profile allow the quick transfer of heat from the element to the sheath for efficient operation to 1400 F sheath temperature. Watt densities as high as 200 watts per square inch on small diameters and 100 watts per square inch on larger diameters are possible. The Mighty-Tuff can stand up to shock, vibration and many contaminants long after standard band heaters have failed. In normal use, or in the most difficult application, the Mighty-Tuff will improve machine productivity by improving band heater performance.

  • Stainless Steel Sheath to resist oxidation
  • Capable of operating up to 1400 F Sheath Temperature
  • Highest possible application temperatures
  • Over 200 watts per square inch capacity
  • Thin profile (3/16") for rapid response

Mighty Tuff Heater Temperature Curve
Maximum Watt Density for 1-1/2" Wide Mighty-Tuff Band Heaters:
  • Cycled moderately.
  • Tightly clamped on a smooth surface.
  • For units over 2" in width multiply watt density by 0.8.
  • Where insulating blankets are used, multiply watt density by 0.7.
  • See the technical section for estimating watt density.
