Skin Effect Heat Tracing System

A ThermTrac system provides a cost-effective alternative to conventional resistance heat tracing on long pipelines by eliminating the need for an extensive power distribution system. A pipeline up to 15 miles (25 kilometers) long can be traced from a single power point. The versatility of the system makes it ideal for temperature maintenance, freeze protection and heat-up applications.

The system generates heat in the "Heat Tube" by the return electrical current flowing through the impedance of the inner skin of the heat tube. There is no voltage or current on the outer skin of the heat tube.

The ThermTrac insulated conductor is the heart of Thermon’s skin effect heating system. This conductor is custom designed by Thermon with dielectric insulation and scuff jacket to meet specfic project applications. For freeze protection and low temperature maintenance applications, polyolefin-insulated nickel plated copper conductors may be utilized. Fluoropolymer-insulated nickel plated copper conductors provide superior temperature, flexibility and durability properties necessary for higher temperature applications.

Maximum Maintenance Temperature: 392°F
