Nelson™ Heat Trace 230V Type XLT Self-Regulating Heater Cable
Brand: NelsonNelson™ Heat Trace XLT Series self-regulating heater cable is ideal for maintaining fluid flow over a wide range of operating temperatures.
The product is used for freeze protection of periodically steam (29 BAR) cleaned pipes and temperature maintenance for 232 °C or lower processes.
XLT Series are 230 Volt heating cables designed for use in ordinary (unclassified) and hazardous (classified) locations. Typical applications include hydrocarbon and chemical product piping.
Features- Type XLT self-regulating heater cable is a parallel circuit electric heater strip. A conductive fluoropolymer core material is extruded over the multi-stranded, nickel-plated, 2.1mm² copper bus wires. A fluoropolymer jacket provides excellent dielectric strength, moisture resistance, protection from impact and abrasion damage, and a wide range of chemical resistance. A stranded tinned copper metal braid and fluoropolymer overjacket is supplied on all heaters.
- 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 developing. The heater cable derives its self-regulating characteristic from the inherent properties of the conductive core material. As the core material temperature increases, the number of conductive paths in the core material decreases, automatically decreasing the heat output. As the temperature decreases, the number of conductive paths increases, causing the heat output to increase. This occurs at every point along the length of the cable, adjusting the power output to the varying conditions along the pipe. As the cable self-regulates its heat output, it limits the maximum sheath temperature, while also providing useful power for process temperature maintenance.
