Aluminum Band Heaters
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%.

B Style
The 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 Style
Stainless-steel braids provide strength and protect leads from abrasion. However, leads should never be pulled or used as transportation handles.
H Style
Encasing 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 Style
Teflon 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 Style
NEMA-1 enclosures provide protection against exposed electrical wiring and terminals. Enclosure dimensions can change with heater size.
G4 Style
Aluminum Band heaters can have NEMA-4 moisture and contamination proof enclosures which are brazed or welded to the tubular elements.
Partial
Partial Aluminum Band Heaters are recommended where obstruction or complicated holes prevent complete coverage on the surface of the barrel.
Insulated
To prevent energy loss, Aluminum Band Heaters can have separate insulating shrouds. These shrouds are custom-made as per heater specs.
Reverse
Reverse constructions are for applications that require internal heating. Electrical terminations and reverse clamping mechanisms are located on the inside of the heater.

FAQs
What are the main applications of aluminum band heaters?
These are great low temperature options for the replacement of Cast heaters
How do I maintain and clean an aluminum band heater?
The surface should be cleaned and the mounting should be firmly clamped.
Why is aluminum preferred over other metals for band heaters?
The thermal transfer of Aluminum is very good.
How does the thickness of the aluminum band affect heating efficiency?
The more material there is, the higher the power needs to be, so a thin profile is more efficient.
Why is my aluminum band heater not reaching the set temperature?
This could be due to incorrect placement of a sensor, or the power rating of the heater.
