nVent Thermal Management provides power limiting heat trace cables that allow for higher exposure temperature and higher power output at elevated temperatures.

nVent RAYCHEM heat trace cables are parallel heaters formed by a coiled resistor alloy heating element wrapped around two parallel bus wires. At a fixed distance, the insulation is removed from the alternate bus wires to form a heating zone.

The positive temperature coefficient effect (PTC) of the heating element reduces power output as ambient temperature increases. This effect allows the power-limiting cable to be overlapped by reducing the temperature of the heating element at the overlap points.

Power-limiting heat trace cable can be used for freeze protection and process temperature maintenance requiring high power output and/or high temperature exposure. Power-limiting cables can provide process temperature maintenance up to 455°F (235°C) and can withstand exposure temperatures up to 500°F (260°C) with power off.
