Band Heaters

Band Heaters are one of the most widely used electric heating solutions for heating cylindrical surfaces, pipes, barrels, dies, extruders, and processing equipment. Designed to deliver efficient and uniform heat transfer, band heaters play a critical role in plastics processing, packaging, food production, manufacturing, and industrial process heating applications.

At Backer Cynebar Ohmic, we supply high-quality industrial band heaters engineered for reliability, precise temperature control, and long service life. Whether you require a standard replacement heater or a custom-designed solution for OEM equipment, our engineering team can help specify the right heater for your application.

Band heaters are electric heating elements designed to clamp around cylindrical surfaces and transfer heat through conduction directly into the equipment being heated.

They are commonly installed on:

Because the heater is in direct contact with the heated surface, band heaters provide fast thermal response and efficient heat transfer.

Uniform Heat Distribution

One of the key advantages of band heaters is their ability to provide consistent heating around the entire circumference of a barrel or pipe. This helps minimise temperature variations and improves process stability.

Compact and Space Efficient

Band heaters mount directly onto the equipment being heated, making them ideal where installation space is limited.

Precise Temperature Control

When combined with thermocouples, RTDs, or digital controllers, band heaters can maintain accurate process temperatures for critical manufacturing operations.

Reliable Industrial Performance

Modern band heaters are designed to withstand demanding industrial conditions while delivering years of dependable operation.

Mica Band Heaters

Mica insulated band heaters are among the most common designs used throughout industry.

Benefits include:

Ceramic Band Heaters

Ceramic band heaters provide higher operating temperatures and improved insulation performance.

Advantages include:

Ceramic heaters are frequently selected for extrusion and heavy-duty process applications.

Insulated Band Heaters

For applications focused on energy efficiency, insulated band heaters can significantly reduce heat loss from the barrel surface.

Benefits include:

Plastics Processing

Band heaters are extensively used throughout the plastics industry for:

Consistent temperature control is essential for product quality and repeatable manufacturing results.

Packaging Equipment

Many packaging machines rely on accurate heating for sealing, forming, and material handling processes.

Food Processing

Specialised band heaters can be used for food production equipment where controlled heating is required within hygienic processing environments.

Industrial Manufacturing

Band heaters are commonly installed on:

They provide a simple and effective heating solution for a wide variety of industrial applications.

Heater Fit and Contact

Proper contact between the heater and barrel surface is critical for efficient heat transfer.

Poor fitting heaters can lead to:
