Heating cables are made for a wide variety of industrial, commercial and residential applications. By offering an array of cable technologies — such as self regulating, power limiting, mineral insulated, skin effect, constant wattage and series resistance — our heating cables meet the needs of most applications including process temperature maintenance, pipe freeze protection, longline heating, flow assurance, hot water temperature maintenance, roof and gutter de-icing, surface snow melting, frost heave prevention and floor heating.

Q:What are Self-Regulating Heating Cables?
A:1.Any heating cable providing a watt output which increases as temperatures fall and decreases as temperatures rise. Self-regulating heating cables use a carbon matrix-heating element with variable resistance.
2.Self-regulating cables have a conductive polymer-heating element where the resistance exhibits a PTC characteristic, the resistance of the element increases with temperature. Conversely, the cable’s power output decreases with increasing temperature. As the temperature increases the cable power output approaches zero. At this temperature the cable effectively “shuts off”. A hazardous area T-rating can be assigned to self-regulating cables regardless of installation conditions.
3.Being a parallel construction, the self-regulating heating cable can adjust its power output for local condition along its length.
Q:Can TubeTrace be manufactured with different colored outer jackets?
A:Yes, most any color is possible. Additional manufacturing set-up costs may apply.
Q:For heat tracing systems, is thermal insulation really necessary?
A:Yes. The heat losses without thermal insulation are excessive and not practical to compensate for with heat tracing.
