Pentair Thermal Management provides self-regulating heating cables that automatically adjust their power output to compensate for temperature changes.
Raychem brand self-regulating heating cables consist of two parallel conductors embedded in a heating core made of conductive polymer. The core is radiation-crosslinked to ensure long-term reliability.
How Self-Regulating Heating Cables Work
Heat is generated as electric current passes through the conductive polymer core between the cable’s conductors. As the ambient temperature drops, the number of electrical paths through the core increases and more heat is produced. Conversely, as the temperature rises, the core has fewer electrical paths and less heat is produced.
Raychem's self-regulating heating cable technology is available in a range of products suitable for use in the home, in construction for larger buildings, and for industrial-based applications.
