The distribution box, as the "control core" of the electric heating cable system, enables zoned temperature control and data recording, providing early warning of freezing and blockage risks, and ensuring stable heating of long-distance pipelines. tracing system is much more than just the heating cable. Versatile equipment manufactured by TEP Ex may be used fo power connection, in-line and. industrial plants and facilities. Software solutions with TRACE-VISION and integrated bas lutions for specific require ol can be used in hazardous areas. Tempera-tures are the maximum permissible exposure temperatures. Our project engineers will be glad to assist you to design and di ension. Electric heat trace, or surface heating, is the application of heat to an external surface that compensates for heat lost due to changes in temperature in ambient surroundings. In cold or freezing conditions, heat tracing systems help stabilize surface temperatures of pipes or vessels via electric. Our Heat Trace Control product range includes industry leading thermostats, heat trace controllers, distribution systems and our powerful Supervisory Control Software Whether you are managing 1 circuit or 10,000, Chromalox offers best in class heat trace control solutions for industrial and. We can design and build custom temperature control assemblies and can design a controller for your process heating application.
