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...

BAND HEATERS component parts ELECTRICAL TERMINATIONS Select among the following electrical terminations based on the requirements of your application. Each termination has its own features, benefits, and limitations. Please consider the following factors when selecting your termination type: Notes: Terminal boxes prevent electrical shocks and short by encasing the terminals in a sturdy stainless steel box. Below is a size chart of the various types of terminal boxes. Specific boxes are used for three-phase and dual voltage application requirements. Diameter Width Voltage Amperage Operating...

BAND HEATERS component parts TERMINATION CATEGORIES CONT’D Straight lead exit Stainless steel braid • For applications with regular movements or with a risk of abrasion. • Includes heat shrink sleeving at leads’ end to protect the braid form fraying. Used mostly with nozzle heaters Low profile terminal cover Straight lead exit Plain lead wire • For applications without risk of abrasion or contamination. • Standard temperature wire with fiberglass insulation: 840°F. • Teflon insulated wire available. Exiting on both sides of the gap Used mostly with nozzle heaters 180° from gap NEED...

BAND HEATERS When selecting the construction model of a WATTCO™ mica band heater, please consider the following factors: CONSTRUCTION MODELS component parts TO CONSIDER WHEN SELECTING WATT DENSITY • Maximum performance • Ease of installation The most popular construction models are: • One piece o For a heater installed on a barrel without extensive expansion o Diameter: 5/8” to 22” o Width: 5/8” to 14” Clean the cylinder properly. 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...

CERAMIC BAND HEATERS component parts BENEFITS OVERVIEW 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. Energy efficient Energy saver Highly flexible Durable Maintains heat Provides uniform heat distribution CSA and CE certified KEY FEATURES APPLICATIONS •...
