Nelson™ Heat Trace 230V Type LLT Long Line Self-Regulating Heater
Nelson™ Heat Trace™ 230V Type LLT Long Line Self-Regulating Heater
Nelson™ Heat Trace LLT Series self-regulating heater cable is ideal for maintaining fluid flow under low ambient conditions.
It is an LT heater cable with extended circuit lengths for longer continuous runs. The product is used for freeze protection and low watt density process temperature maintenance of pipes and vessels. LLT Series are 230 Volt heating cables designed for use in ordinary (unclassified) and hazardous (classified) locations. Typical applications include water freeze protection and low watt density process temperature piping systems such as caustic lines.

Features

  • Type LLT self-regulating heater cable is a parallel circuit electric heater strip. An irradiation cross-linked conductive polymer core material is extruded over the multi-stranded, tinplated, 5.3 mm² copper bus wires. Two jackets provide extra diele
  • 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 creati
