FSR self-regulating heating cables provide the most versatility in heat trace designs and for various applications, including pipes, roofs, gutters, and other structures. 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 temperature increases, the heater’ s resistance increases, which lowers the output wattage. Conversely, as the temperature decreases, the resistance decreases and the cable produces more heat. So thermostat is not necessary in some applications. FSR self-regulating heating cables will never overheat or burnout even when overlapped. The cable can also be cut to any length. As the result, we get an energy efficient heating cable. With optional outer jackets, the heating cable is resistant to watery and inorganic chemicals and protected against abrasion and impacted damage.
FSR heating cables can be used in hazardous areas. FSR adjusts to respond to various temperature changes and provides freeze protection. The self-regulating mechanism ensures that the cable produces heat when needed to prevent freezing.
The heating cables are designed with safety in mind by preventing overheating and potential fire hazards. FSR is relatively easy to install. They are energy efficient compared to constant-wattage cables.
