Self Regulating Heat Tracing Cable
Marathon Heater’s self-regulating heating cable provides the most versatility in heat trace design and applications. Constructed of a Semi-conductive heater matrix extruded between parallel bus wires, a self-regulating cable adjusts its output to independently respond to ambient temperatures all along its length. As temperatures increase, the heater’s resistance increases which lower the output wattage. Conversely, as the temperature decrease, the resistance decreases and the cable produces more heat. So there is no need of thermostat in some applications. It will never overheat or burn out even when wrapped by itself(overlapped). It can be cut to any length, hence it is an convenient, easy to use and energy-saving product.
