Heat Tracing Cables

Canadian winters can be brutal. Don't be left out in the cold.

Create your bill of materials now

No matter how cold the weather gets, you won’t have to worry about frozen pipes, ice dams or slippery sidewalks, when your facility has 24-hour protection against freeze-ups, provided by 3M™ Heat Tracing Cables.

Save on electricity by putting heat exactly where it’s needed, instead of wasting energy to heat the entire length of the cable. 3M heat tracing cables are an energy-saving alternative to conventional “constant wattage” cables that heat uniformly along their entire length. Constructed using an advanced carbon polymer materials technology, 3M heat tracing cables are self-regulating – meaning they adjust their heat output automatically in response to ambient air temperatures along every inch of their length.

The science behind 3M heat tracing cables

As the ambient temperature surrounding a particular section of cable drops, the electrical paths in the carbon-polymer heating matrix become shorter, decreasing its resistance. This causes the heat output of that section of cable to increase.


Conversely, when the ambient temperature rises, the resistance of the heating matrix increases, which lowers the heat output. This effect allows the cable to “self-regulate” its heat output, without the need for separate thermostats.

 
 
 
 
 
 
 
 
Heating Matrix

The heating matrix provides an infinite number of parallel resistances. This allows the heating cable to adjust its heat output in response to temperature conditions at any point down its length.

3M™ Self-Regulating Heat Tracing Cables

3M™ Self-Regulating Heat Tracing Cables consist of a conductive polymer heating matrix contained between two parallel bus conductors. The cable can be cut to any desired length without changing its properties.

Whether you're working on a small project or a complex network, designing a system with 3M heat tracing cables is quick and easy.

  • A pipe and valve frozen in a build-up of ice.

    Pipe freeze protection

    TTS™ Series cut-to-length self-regulating heating cables are designed to provide freeze protection for metallic and non-metallic pipes by replacing the heat lost by the pipe through thermal insulation.

  • Snow on a roof, with icicles hanging from the eavestrough.

    Roof and gutter snow and ice melting

    TTS™ Series cut-to-length self-regulating heating cables are designed to provide snow and ice melting for roof and gutter applications.

  • An older couple walking through a parking lot during winter.

    Surface snow and ice melting

    KSR™ Series cut-to-length self-regulating heating cables are designed to provide snow and ice protection for concrete and asphalt walks, driveways and other applications. Designed and approved specifically for direct burial, KSR cable is ruggedized, to help prevent damage during installation.

  • Hot Water Temperature Maintenance

    Hot Water Temperature Maintenance

    HSX™ 2100 series cut to length self-regulating heating cables are specifically designed to maintain hot water supply piping at desired nominal maintenance temperatures. With 14 AWG bus wires, HSX™ 2100 series can reduce the number of circuits required to install an electric heat-traced system.
