Thermal Controls provides self-regulating heating cables that automatically adjust their power output tocompensate 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.
Heat is generated as electric current passes through the conductive polymer core between the 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 system technology is available in a range of products suitable for use in the
home, in construction for larger buildings, and for industrial-based applications.
Tyco Thermal Controls self-regulating systems offer:
Parallel circuitry and flat cable design makes Raychem heat-tracing systems easy to handle and install.
They may be cut to length on site, and overlapped at valves, flanges, and instruments.
Provides high power output as needed. This means fast startup – and less downtime – when pipes
or other application surfaces are cold.
Reduced operating costs
The system compensates for variables such as heat sinks, as well as fluctuations in voltage
and temperature. Heat is automatically supplied only when and where needed.
Because the heater senses and responds to actual conditions along the pipe, the system automatically
accommodates variations due to static fluid and differing elevations.
Our self-regulating heating cables offer unconditional T-ratings, as specified by the National
