CLAMPING MECHANISM INDEPENDENT STRAP BUILT-IN BARREL NUTS SPOT-WELDED STRAPS FLANGE LOCK-UP WEDGE LOCK SPRING-LOADED BARREL NUTS CLAMPING PADS {AND HEATERScomponent parts FEATURES 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...

Firmly tighten the heater on the cylinder. Gently tap the rims with a plastic mallet. Tighten the heater again. Compensate for thermal expansion by using large diameter heaters with spring-loaded...

ELECTRICAL TERMINATIONS Durable, WATTCO™ ceramic heaters provide excellent energy efficiency with their built-in ceramic fiber jackets. Unlike mica band heaters, ceramic heaters transfer heat through conduction and radiation and do not require tightening around the cylinder. Flexible, these heaters come in a wide variety of terminal styles, and with different clamping mechanisms, holes and cutouts. KEY FEATURES » Nickel-chrome wire in a outer wall composed of interlocking ceramic tiles. » Inside medium-high temperature heaters up to 1200°F » Outside shell temperature: 350° - 450°F »...
