MSR Medium Temperature Electric Self Regulating Heat Tracing Cable
Application
MSR series heat tracing cables are exceptional heating cables. Constructed of a semi-conductive heater polymer (also named as “PTC”) extruded between parallel bus wires with the addition of insulation layer. They are widely applied to pipelines and storage tanks for process temperature maintenance.
Constrution
With a holding temperature up to 105℃,MSR self-regulating heat tracing cables are fit for various applications, except for those of steam purging. Also, they can be used for anti-freeze of large pipes and applications where medium exposure temperatures are required.
Characteristics
MSR-J is the basic middle temperature heating cable type, with the Max.maintain temperature up to 105℃ (221°F), while the Max.exposure temperature is 135℃ (275°F).Generally used in places where there is no explosion-proof or anti-corrosion requirements, and the environmental humidity is not high.
MSR-P/F is enhanced with an additional aluminum-magnesium alloy braid(tinned cooper for option), sheathed by a fluoropolymer out jacket. Compared to MSR-J, it has a good performance on anti-corrosive, also with characteristic of explosion proof, ideal for places with explosion-proof requirements, especially chemicals, power supply and other places need corrosion resistance.

Advantage
1. Energy saving: Due to the unique PTC property, the cable adjust the output power respond to ambient temperature.
2. Easy installation: PTC semi-conductive matrix is composed of the infinite parallel connection of carbon particles, allowing it to be cut into the exact length required.
3. Long service life: A lower starting current and attenuation rate ensures our cables provide you a longer service life.
4. Safety for use: Can be overlapped by themselves without the danger of overheat or burnout.
5. High quality with low cost: self- regulating, easy operation, low cost to maintain. No recycled material used, all the components are manufactured by our own factory, which means better quality and competitive cost for you.
