The heating element is multi-strand resistance wire, braided with AMOX™ yarn and knitted into the serpentine shape to minimize thermal shock and tensile stress from expansion and contraction. The side-by-side wire configuration permits the lead wires to be on one end. The Duo-Tape®
configuration is the most popular of all our flexible elements.
Extruded in Silicone Rubber
The silicone encapsulates the element in a soft, (50 durometer) extrusion. Flexible and durable, the ASR tape will wrap around small ¼ in. (6mm) tubing. The Silicone Duo-Tapes®
may be used on conductive surfaces (use directly on metal), and the silicone extrusion provides resistance to moisture, chemicals, and abrasion. Heat additives provide capability to 450°F (232°C).
Molded Plug Option (120V)
Standard ASR tapes do not include a power plug. 120V tapes may be ordered with the optional molded plug (-MP). No power plug option is available for 240V tapes. Commercially available connectors may be installed for the customer or sourced locally. Duo-Tapes®
do not utilize a grounding circuit and provide a two wire connection. For Earth Ground Leakage protection a circuit protector (30ma GFCI) is recommended.
