Band Heaters

Band heaters provide countless solutions for cylindrical surface heating applications. For other cylindrical or non-cylindrical surfaces we recommand cartridge-, circulation-, immersion-, strip-, tubular- or flexible heaters.

Band heaters are manufactured in many different configurations.

The main constructions:

1. Band heaters with Mica insulation
2. Band heaters with Ceramic insulation
3. Band heaters with Mineral insulation
4. Tubular heaters embedded in aluminum

 Mica Band Heaters

This thin profile construction allows high watt densities up to 55 watts per square inch and quick heat transfer from the element to the sheath for efficient operation up to 800 degF sheath temperature. A stainless steel sheath encases a compressed mineral refractory which surrounds a helical or sinuated resistance element. We also offer band heaters up to 200 WSI. Contact us. With SCR or SSR power control output, watt densities can be increased up to 30%.

Ceramic Band Heaters

This heaters are used for plastic molding, extrusion and molding presses or any application where there is a need to apply heat to a cylindrical surface. They are very energy efficicient since they have a standard 1/4in thick insulation. A 1/2in thick insulation is optional. Up to 18in diameter it can be a 1 piece construction, greater than that we recommand a 2-piece construction. Ceramic Band heaters can be manufactured in widths much greater than what is practical in Mica Band heaters, eliminating heat losses between gaps in narrow band heaters and simplyfying installation. With SCR or SSR power control output, watt densities can be increased up to 30%.

Important other elements:

• temperature sensor
• temperature control
• electrical power switching

Band Heater Applications

Mica band heaters are economical, thin, efficient heaters up to 800 deg F.

Ceramic band heaters are recommended because efficient heat transfer is not affected by irregular surfaces or loose fit. At higher watt densities they can be used in wider increments than other heaters.
