USX™ Self-Regulating Heating Cable

USX self-regulating heat tracing is specifically engineered for critical process maintenance and freeze protection applications where ultra-high temperature ratings are required. USX enables the use of ambient sensing controls for applications with continuous exposure temperatures up to 240°C (464°F). Constructed using Thermon’s unique and proven monolithic co-extrusion process, USX advances self-regulating heat tracing technology to the ultimate frontiers of performance and reliability.

The heat output of USX heat tracing varies in response to the surrounding temperature. Variations in the ambient temperature or heat lost through the thermal insulation are compensated for automatically along the entire length of a heat-traced pipe.


  • Higher continuous operating and exposure temperatures 240°C (464°F), creating new possibilities for reliable self-regulating technology
  • Thermon’s unique and proven monolithic co-extrusion technology provides superior performance and reliability
  • Enhanced safety and ease of installation for electric heat tracing systems for high temperature applications
