Nelson™ Heat Trace Type HLT Self-Regulating Heater Cable
Nelson™ Heat Trace™ Type HLT Self-Regulating Heater Cable
Nelson™ Heat Trace HLT Series self-regulating heater cable is ideal for maintaining flow over a wide range of operating temperatures.
The product is used for freeze protection of periodically steam (200 psig) cleaned pipes and temperature maintenance for 121 °C (250 °F) or lower processes. HLT Series heating cables are available in 120 and 240 voltages and are designed for use in ordinary (unclassified) and hazardous (classified) locations. Typical applications include hydrocarbon and chemical product piping.

Features

  • Type HLT self-regulating heater cable is a parallel circuit electric heater strip. A conductive fluoropolymer core material is extruded over the multi-stranded, nickel-plated, 16-gauge copper bus wires. A fluoropolymer jacket provides excellent dielectri
  • Operating principle: The parallel bus wires apply voltage along the entire length of the heater cable. The conductive core provides a continuous parallel heating element permitting the cable to be cut to any length in the field with no dead or cold zones
  • Voltage ratings: 240 Vac products are suitable for use on supply voltages of 208-277 Vac. See catalog pages for details.
