Aluminum Band Heaters
Bucan Aluminum Band Heaters are used in applications where rugged, long lasting heaters are needed. These heaters are highly efficient in transferring heat to the application surface, provide uniform heating, are contamination proof (apart from the terminals) and easy to install.
The heat source is a set of 0.315in tubular heating elements which are pressed into tight grooves made on the surface of the heater aluminum structure.
The heater assembly is clamped around a cylinder or pipe with low expansion stainless-steel straps that have special mounting brackets that use barrel-nuts, spring loaded ¼-20 socket cap screws that keep the heater tightly clamped to the cylinder even when thermal expansion occurs.
Bucan Aluminum Band Heaters can have different diameters but are available only in four standard widths 1.5”, 2.5”, 3” and 4”. They can have different constructions, termination styles and can accommodate thermocouple holes.
Bucan Aluminum Band Heaters are also available with copper or stainless-steel liquid cooling tubes. This may restrict the thermal capacity by up to 25%.
Typical Heating Applications:
- Plastic Extruders
- Injection Molding Machines
- Blow-Molding Machines
- Dies and Die-Heads
- Pipe and Cylinder Heating

B StyleThe standard termination for Aluminum Band Heaters is the terminal lug with a 10-32 binder head screw. Terminal jumpers are available for easy wiring installations. |
|
E StyleStainless-steel braids provide strength and protect leads from abrasion. However, leads should never be pulled or used as transportation handles. |
|
H StyleEncasing cables in metallic flexible tubing is the ideal method to protect leads from abrasion and contamination. Sharp bending is not possible with this type of leads. |
|
T StyleTeflon leads with Teflon heat shrink sleeves provide excellent protection against moisture and contamination. The temperature limitation for this type of leads is 500°F. |
|
G1 StyleNEMA-1 enclosures provide protection against exposed electrical wiring and terminals. Enclosure dimensions can change with heater size. |
|
G4 StyleAluminum Band heaters can have NEMA-4 moisture and contamination proof enclosures which are brazed or welded to the tubular elements. |
|
PartialPartial Aluminum Band Heaters are recommended where obstruction or complicated holes prevent complete coverage on the surface of the barrel. |
|
InsulatedTo prevent energy loss, Aluminum Band Heaters can have separate insulating shrouds. These shrouds are custom-made as per heater specs. |
|
ReverseReverse constructions are for applications that require internal heating. Electrical terminations and reverse clamping mechanisms are located on the inside of the heater. |
