Tab1 Image SRD Duo-Tapes® ...Rugged & Flexible, Constant Wattage output.

SRD Duo-Tapes® are silicone heaters, and differ from self-regulating heater cables in that this silicone industrial tape has a constant wattage output. This custom heating tape is constructed specifically for industrial applications that require continuous heat for process temperature maintenance. Sometimes a self-regulating heater cable doesn’t cut it – instead SRD Duo-Tapes®, with their constant output of 15 or 30 watts per foot, can provide the heat needed for these applications. SRD, silicone heaters, are ideal for industrial applications that need continuous heat for process temperature maintenance.

Other cables often fall short when exposed to high temperatures, but this line of silicone industrial tape is up to the task. These heaters have the ability to hold process temperature, where other cables don’t. The Duo-Tapes® can maintain continuous temperatures of up to 450 degrees F (232 degrees C) and even intermittent temperatures of up to 482 degrees F (250 degrees C).

HTS/Amptek® developed this line of heaters to be similar to the higher watt density Laboratory ASR Silicone Duo-Tapes®, but offer longer lengths, longer lead wire lengths, and rugged, lead wire terminations.

SRD Duo-Tape® with Silicone Rubber Extrusion

Similar to the HTS/Amptek® Laboratory ASR Silicone Duo-Tapes®, SRD Duo-Tapes® offer low watt density, longer power lead lengths, and rugged, sleeved lead wire termination. Element construction incorporates stranded, Ni or CuNi alloy wire, braided with fiberglass or AMOX™ yarn. The multi-strand resistance wire assembly is knitted into the serpentine shape to minimize thermal shock and tensile stress (2 wire Duo-Tape® element shown). The complete Duo-Tape® is encapsulated in a continuous silicone rubber extrusion. Terminations are captured under vulcanized rubber caps.
