Catalog/Specifications Sheet
Q: What is self-regulating cable?
A: Self-regulating cable, also known as heat tape or heat trace, is a semi-flexible heating cable that automatically regulates its heat output based upon surface temperature and ambient conditions. It is often used for freeze protection applications to wrap or trace pipes, tanks, vessels, roofing and much more.
Q: What is the difference between self-regulating and constant wattage heating cable?
A: Self-regulating heating cable automatically adjusts its heat output based on the surrounding temperature. It produces more heat in colder areas and less heat in warmer areas. Constant wattage heating cable delivers the same heat output along its entire length regardless of ambient conditions.
Q: When should I use self-regulating heating cable?
A: Self-regulating heating cable is ideal for freeze protection and temperature maintenance applications where temperatures may vary along the pipe or equipment. It is commonly used for:
- Water pipes
- Process piping
- Roof and gutter de-icing
- Tanks and vessels
- Industrial freeze protection
Q: When should I use constant wattage heating cable?
A: Constant wattage heating cable is often used when a consistent heat output is required across the entire circuit. Common applications include:
Process temperature maintenance
- Long pipe runs
- Industrial equipment
- Viscosity control
- Applications with predictable heating requirements
Q: Can heating cable be used outdoors?
A: Yes. Many heating cables are designed for outdoor environments and can be used on exposed piping, tanks, valves, roofs, gutters, and process equipment. Our low temperature self-regulating heating cable, mid temperature self-regulating heating cable, high temperature constant wattage cable, and speedtrace self-regulating heating cable are suitable for outdoor use. Several constant wattage cable models are moisture and chemical resistant. Always confirm environmental ratings before installation.
Q: What voltages are available for heating cable?
A: Heating cable is available in multiple voltage options, including:
- 120V
- 208V
- 240V
- 277V
- 480V
Q: Is a temperature control needed for your Self-Regulating Heating Cable?
A: BriskHeat Self-Regulating Heating Cable should be used with an appropriate temperature controller to save energy and ensure the cable is only energized during cold periods, but it is not required. Temperature control is also necessary to maintain a specific process temperature.
