Product Name: MSR



MSR Self Regulating Heating Cables provide the most versatility in heat trace designs and applications. Constructed of a semiconductor 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 heaters resistance increases which lower the output wattage. Conversely, as the temperature decreases, the resistance decreases and the cable produces more heat. So it does not need thermostat in some applications. It will never overheat or burnout even when wrapped by itself (overlapped). The cable can also be cut to any length. The result — an energy efficient heating cable.

1.Long life time: PTC semi-conductive matrix with high quality and excellent technology.

2.Low energy consumption: Due to unique PTC property, the cable adjusts the output power respond to ambient temperature.

3.Excellent heat resistance: PTC semi-conductive matrix is treated by irradiation crosslinking reaction. High insulation resistance.

4.Cut to length: PTC semi-conductive matrix is composed of the infinite parallel connection of carbon particles, allowing it to be cut to the exact length required.

5.Easy for installation: Linear cable, complex installation available, never overheat when overlapped.

6.Low starting current: PTC 3 layer co-extruded technology, low starting current and low Attenuation rate.

7.Cable durable: UV protection, high and low temperature resistant, weather resistant.




MSR is ideally used for process temperature maintenance and frost protection of small diameter pipelines, tanks, valves, flanges. It is suitable for hazardous area, also non-hazardous area and corrosive area with fluoropolymer outer jacket. What's more, the MSR with Fluoropolymer out jacket can be used inside the water pipe heating. The material has the drinking water certificate. It's safety and made to comply with the environmental protection standards.
