Thermal Controls & Electronics

Application

Thermon USX self-regulating heat tracing cables are specifically engineered for critical process maintenance for temperatures up to 240°C 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. 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 the USX cables varies in response to the surrounding conditions along the entire length of a circuit. Whenever the heat loss of the insulated pipe, tank or equipment increases (as ambient temperature drops), the heat output of the cable increases. Conversely, when the heat loss decreases (as the ambient temperature rises or product flows), the cable reacts by reducing its heat output. USX heat tracing cables are available with a fluoropolymer (FOJ) overjacket for higher chemical resistance against aggressive organics and corrosives.

The USX heat trace cables are approved for use in ordinary (nonclassified) areas and hazardous (classified) areas.
