BAND HEATERS CLAMPING MECHANISM component parts FEATURES INDEPENDENT STRAP 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. BUILT-IN BARREL NUTS 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. SPOT-WELDED...
