Heating cable DANFOSS 935W/52m (18W/m) self-regulating electrical heat-tracing cable

The DANFOSS heating cable 935W/52m is a self-regulating electrical heat-tracing cable that delivers approximately 18 W per metre and a total rated output of 935 W over 52 m. It is designed to maintain temperatures, prevent pipe freezing and provide de-icing for roofs and gutters when installed with appropriate insulation and connection accessories. The self-regulating polymer core modulates heat output in response to ambient temperature, reducing the risk of overheating and improving energy efficiency in fixed installations.

Advantages

This heating cable offers self-regulating power output that increases heat where it is coldest and reduces output where it is warmer, which lowers energy consumption compared with constant-power tracing in variable ambient conditions. The cable is suitable for continuous outdoor and indoor use when correctly installed and provides a simple solution for maintaining process temperatures and protecting infrastructure from freeze damage. Its linear power density (approximately 18 W/m) makes it predictable for thermal calculations and insulation selection.

Suitable for

• Pipe freeze protection for water and drainage systems
• Roof and gutter de-icing to prevent ice dams
• Maintaining temperature in process lines and valves
• Applications requiring distributed heat along a run of pipe or gutter

When it may not be suitable

This self-regulating cable is intended for fixed installations and must be used with appropriate insulation, end seals and connection kits; it is not a temporary or portable heating solution. It may not be the best choice where exact surface temperatures must be maintained to tight tolerances without additional temperature control devices, or where a higher or lower linear wattage than approximately 18 W/m is required for a particular application.

Key specifications

• Type: Self-regulating heat-tracing cable
• Total rated output: ~935 W over full length
• Nominal power density: ~18 W per metre
• Length: 52 metres
• Application environment: indoor and outdoor fixed installations with suitable insulation and accessories

How to use

Install the cable along the length of the pipe, roof channel or gutter to be protected following local electrical codes and the manufacturer's installation instructions. Fix the cable to the substrate with appropriate clips or tape, maintain the recommended spacing and avoid crossing or overlapping of the cable. Provide proper end seals, splice kits and connection to a suitably rated power supply and control device or thermostat where temperature regulation or switching is required. After installation, cover with the specified thermal insulation and weatherproofing where applicable.

What to consider before purchase

• Verify required linear wattage for the specific pipe diameter, insulation thickness and ambient conditions
• Confirm the installation length needed and plan for connection and end-of-line kits
• Ensure compatibility with local voltage, electrical codes and available control equipment
• Account for required thermal insulation and mechanical protection in exposed locations

Usage recommendations

Use this self-regulating DANFOSS heating cable in fixed installations combined with suitable insulation and proper connection kits. For best performance and safety, follow the manufacturer's installation guidelines, use recommended accessories, and include temperature controls or thermostats where precise temperature maintenance or energy savings are desired.
