When it comes to maintaining pipe temperature, there are many different types of technology. Depending on your system, and the needs of your application, a self-regulating heat traced system may be the right option. 

Self-regulating heat traced systems come with many benefits for a wide range of applications. Let’s explore how the technology works and how it could benefit your next heat trace project 

How Does the Technology Work? 

When an electric current passes through the polymer core of the cable, heat is generated. When 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.  

This means a self-regulating system will provide more or less heat as needed, making a self-regulating system energy efficient and very effective in lower temperatures 

What are the Benefits of a Self-Regulating Heat Traced System? 

Self-regulating systems are often called the most reliable systems in the world. This is due to their longevity, and other factors:  

  • Easy to use and installSelf-regulating cables can be cut-to-length on site, making them easy to install even in tough spots.  
  • SafeThese cables can be spaced narrowly  and evenly even overlapping multiple times, without danger of overheating 
  • Energy savingBecause these cables adjust their heat output automatically to compensate for ambient temperature changes, heat is only produced when and where it’s necessary. This can give massive energy saving benefits in large system builds.
