Electric self regulating warm cable

The self-regulating heating cable (self-regulating heating cable and auto temperature control heating cable) is a new generation and the only constant temperature electric band heater. The resistivity of the heating element is of extremely high “PTC” (positive temperature coefficient) and these elements are in parallel connection. The characteristics are as follows: it can automatically restrict the heating temperature, and can automatically adjust the output power with the temperature of the heated body with no need of any other additional equipment; it can be cut or connected in a certain length at free will for use, and allows multiple overlapping with no high temperature hot spots or worry about being burnt up. By right of these characteristics, heating cables are provided with advantages including overheating prevention, convenient usage and maintenance as well as energy saving. They are applicable for temperature control, heat trace, insulation and heating of pipes, equipment and containers, especially there is any material easy to break down, deteriorate, crystallize or condense and freeze. They have been widely used in industries including petroleum, chemical industry, power, metallurgy, light industry, foods, freezing, buildings, coal gas, production and processing of agricultural byproducts as well as other departments.
 
The heating cable is composed of nanometer conductive carbon particles, two parallel buses and the insulation layer. All self-regulating heating cables can be cut into sections in any length or connected via two-way or three-way junction box because of this kind of parallel structure.
 
MSR Self Regulating Heating Cables provide the most versatility in heat trace designs and applications. Constructed of a semiconductive 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 decreases, the resistance decreases and the cable produces more heat. So it is no need thermostat in some applications.it will never overheat or burnout even when wrapped by itself (overlapped).Also can be cut to any length.The result —an energy efficient heating cable.
 
MSR is ideally used for process temperature maintenance and frost protection of large diameter  pipelines,tanks,valves, flanges.and other industrial application where have high heat loss.  It is suitable for hazardous area, also non-hazardous area and corrosive area with fluoroplymer outer jacket.
