TRM Self Regulating heating cable is ideal for heat tracing in commercial and residential applications. The semi-conductive core regulates its heat output based on the surrounding temperature and can vary its heat output along the cable's entire length, saving energy and eliminating hot spots along the pipe. Cables are designed to be safely crossed or overlapped to suit site conditions. TRM's SR cable is suitable for applications such as freeze protection, sprinkler tracing, roof and gutter de-icing, heat loss replacement and frost heave prevention. SR cable is a cost effective solution for most heat tracing applications, with a range of product choices that can be designed to match your project's specific requirements. A complete range of accessories and controls are available to complement our SR heating cables.
