Band Heaters

Band heaters are a versatile category of heating elements used in a wide range of industrial and commercial applications. They are designed to provide effective heat transfer and uniform heating by wrapping around cylindrical surfaces, such as barrels, pipes, and nozzles. There are several types of band heaters, each with unique features and benefits that cater to specific requirements and applications.

Each of these band heater types offers unique advantages and can cater to a variety of heating requirements in diverse industries, such as plastic processing, packaging, mold and die heating, and process heating.

  1. Mica Band Heater: These heaters utilize mica as an insulating material, offering efficient and uniform heat distribution. Mica band heaters are cost-effective and widely used for heating applications in plastic processing, injection moulding, and extrusion industries.
  2. Ceramic Band Heater: Ceramic band heaters use ceramic insulation materials to provide excellent heat retention and energy efficiency. They are suitable for higher temperature applications and can withstand more demanding environments.
  3. Flexible Heaters: These heaters are designed with flexibility in mind, allowing for easy installation and removal. They can conform to uneven surfaces or adapt to unique shapes, making them suitable for a variety of applications.
  4. Hinged Mica Band Heaters: Hinged mica band heaters feature a hinged design, making them easier to install and remove. This design is particularly useful in applications where frequent heater replacement or maintenance is required.
  5. Inside Out – Mica Band Heaters: These heaters have the heating element positioned on the inner surface of the band, providing direct heat transfer to the object being heated. This design enhances heat transfer efficiency and provides rapid heating.
  6. Semi Band Heaters (Semi Mica Band Heaters): Semi band heaters offer a balance between the performance of mica band heaters and the flexibility of other heater types. They are designed for applications that require moderate flexibility and efficient heat transfer.
  7. Three-Quarter Band Heater: These heaters cover three-quarters of the circumference of the object being heated, providing effective heat transfer while leaving a gap for easy installation and removal.
  8. EcoBand Insulation: EcoBand insulation is an additional feature that can be added to band heaters, improving their energy efficiency by reducing heat loss. This insulation helps maintain the heater’s performance while reducing energy consumption and costs.


Application Features:

  • Customization: Band heaters come in various types, such as mica, ceramic, flexible, and hinged, allowing for tailored solutions to suit specific application requirements.
  • Uniform heating: By wrapping around cylindrical surfaces, band heaters provide consistent and uniform heating, ensuring optimal performance in various processes.
  • Versatility: Band heaters can be used in a wide range of applications, including plastic processing, packaging, mold and die heating, and process heating, thanks to their unique features and customizable options.
  • Energy efficiency: With options like EcoBand insulation, band heaters can offer improved energy efficiency by reducing heat loss and maintaining their performance while lowering energy consumption and costs.
  • Easy installation and removal: Some band heater types, such as flexible and hinged heaters, are designed for easy installation and removal, making them suitable for applications that require frequent maintenance or heater replacement.
  • Durability: Band heaters, particularly those with ceramic insulation, can withstand demanding environments and higher temperatures, ensuring reliable performance and longevity.
  • Adaptability: Flexible heaters can conform to uneven surfaces or adapt to unique shapes, allowing for effective heat transfer in a variety of situations.
  • Precise temperature control: Band heaters can be configured with or without thermocouples, allowing for accurate temperature management and consistent heating performance in various processes.
