Band Heaters

Straps are tightly clamped around the cylinder’s surface and distribute the drawing force uniformly around the band heater. This force is transferred to the inside windings and improves heat transfer by providing effective surface contact and eliminating air gaps.

Same features as the independent strap. The top sheet is made into a strap by placing barrel nut fasteners on either side of the gap. Barrel nuts are used for holes and cutouts, as an alternative to independent straps

Design is similar to that of the built-in barrel nut. Made of an independent strap fastener that is spot welded to the top sheet on each side of the gap. This type of clamping mechanism is used to accommodate a heated section below the fastener.

The most economical clamping mechanism. Designed for narrow heaters.

Basic design for limited space above the heater. Composed of clamp slides (wedge shape) on the lips of the heater on either side of the gap. Standard height between the inner diameter and the highest point of the wedge lock is 5/16”

clamp releases with a flip of thumb. In the fastened position, the spring-loaded ¼-20 bolt absorbs the thermal expansion.

Designed for a two-section heater band. A piano hinge is required on one side of the heater. Any other type of clamp can be used on the other side. Clearance between the 2 sections of the hinge’s side is 5/16”

Made of independent straps, built-in barrel nuts, and spot-welded straps with longer screws with die springs. Springs tightly affix the band heater for thermal expansion. ¼-20 screws included.

Designed for two-section partial heaters. If a complete band heater cannot be used due to an obstruction, a large gap must be created in order to fasten the heater to the cylinder on either side of the gap. Do not use clamping pads on both sides of the same section of the heater. Thermal expansion may cause the heater to detach from the cylinder.
