Mineral Insulated Band Heaters

Mineral Insulated Band Heaters

What makes mineral insulated heaters unique from other band heaters is that they deliver definite benefits when high operating temperatures are required in industrial/commercial processes. Mineral insulation (MI) materials offer enhanced thermal conductivity in comparison to traditional mica and hard ceramic insulators. This type of industrial grade, mineral insulation supports efficient heat transfers, even distribution, and longer product life. MI heater applications include:

  • Extruders
  • Blown film dies
  • Injection molding machines
  • Other cylinder heating applications

Due to their temperature control capabilities, industrial heaters with mineral insulation can support greater productivity. Our MI band heaters are specially designed for applications featuring high watt density and/or high level operational temperatures.

A mineral-insulated band heater can be securely clamped on a cylindrical shape, allowing for optimal heat transfer. If you need information on the premium performance of these thermal products, contact our knowledgeable staff. We’re dedicated to providing exceptional Hi-Watt customer service as your trusted distributor of industrial process heaters.

Mineral Insulated Band Heaters

You can gain an edge in temperature management with mineral insulated band heaters. For example, you’ll find our mineral insulated heaters from Watlow provide virtually instantaneous temperature control with their high thermal conductivity and low mass design. The chart below details specifications for our mineral insulated heaters:

Material Maximum Opening Temperatures Maximum Watt Densities
°F °C W/in2 W/cm2
Stainless Steel 1400 760 100 15.5
  • Heater operating temperatures to 1400°F (760°C)
  • Watt densities to 100 W/in² (15.5 W/cm²) available on large diameter barrel bands
  • Maximum voltage to 480V

When it comes to industrial electric heaters and process heating equipment, mineral insulation delivers a superior level of performance and component protection. That’s why it’s used in mineral insulated cables, thermocouple sensors and band heaters. Do you need standard or custom heating solutions backed by quality?
