What Is a Band Heater?

Band heaters are ring-shaped industrial heaters designed to clamp around and raise the temperature of a cylindrical element through conductive heat transfer. Most come with an insulation of mineral or ceramic material to reduce environmental heat loss. Here are the key parameters that affect the efficiency and operating capabilities of band style heaters:

  • AC voltage
  • Maximum operating temperature
  • Required watts
  • Maximum sheath temperature
  • Sleeve and insulation materials
  • Mounting and termination types

These types of heaters can be secured permanently around a cylinder or include a quick-release strap to remove and apply to different materials as part of the manufacturing process. Consider the size restrictions and required temperatures to select the optimal size and insulation material.
