Nelson™ Heat Trace Type LLT Long Line Self-Regulating Heater
Brand: NelsonNelson™ Heat Trace LLT Series self-regulating heater cable is ideal for use in maintaining fluid flow under low ambient conditions.
The product is used for freeze protection and low watt density process temperature systems that require extended continuous circuit lengths.
LLT Series heating cables are available in 240 Volts and is designed for use in ordinary (unclassified) and hazardous (classified) locations.
Features- Type LLT heater cable is parallel, self-regulating with a radiation crosslinked conductive heating core extruded continuously over two parallel 10-gauge bus wires. A primary dielectric jacket is thermally bonded to the heating core to prevent moisture penetration and a secondary dielectric jacket is extruded over the first. Heater construction includes a tinned copper braid and an overjacket.
- Operating principle: The heating core varies power output inversely with temperature at every point along the heater length, reducing any heat build up at portions of the piping system. This feature also permits the heater to be overlapped without creating hot spots. Reduced power output at higher pipe temperatures reduces energy consumption. Parallel construction permits the heater to be cut to length at any point without changing rated power output.
- Voltage ratings: 240 Vac products are suitable for use on supply voltages of 208-277 Vac. See catalog pages for details.
