The INDEECO LSRX is a self-regulating electric heat trace cable engineered for freeze protection and process temperature maintenance on metal and non-metal pipes, vessels, and equipment. Its PTC (Positive Temperature Coefficient) semi-conductive core automatically adjusts heat output in response to the surrounding temperature along the entire length of the circuit — delivering more heat where it's cold and reducing output as the pipe warms up. This means the LSRX will never overheat, even where cables overlap, and it uses only the energy the system actually needs. Field-cuttable to length and completed with INDEECO system connection kits, the LSRX installs quickly and is approved as a complete system for both ordinary and hazardous (classified) locations indoors and outdoors.
