Heat tracing

Trace heating systems based on mineral insulated sheathed cables up to 1000°C

Trace heating systems based on mineral insulated sheathed cables up to 1000°C

Heat tracing systems are the universal answer to the most diverse requirements for heating or warming media in pipes, containers and individual construction solutions. They are flexible to install and enable the transfer of high heat output. In some cases, trace heating systems are exposed to high mechanical requirements and a wide range of environmental influences. Heat tracing systems from ThermoExpert meet individual requirements because they are based on the technology of mineral-insulated sheathed cables.

Mineral-insulated heating cables consist of a live inner conductor (heating wire) that is shielded against the metal sheath with magnesium oxide as an insulator. The outer diameter of the sheathed cable and the quality and thickness of the inner core have a significant influence on the resistance and therefore on the heat output of the trace heating. The choice of sheath material determines the maximum operating temperature and chemical resistance under the customer-specific environmental influences.

Trace heaters made of mineral-insulated heating cable are very robust and can generate temperatures of up to 1000°C on the heating conductor, depending on the design. Their closed metal sheath protects the trace heating from the ingress of moisture, gases or other media.

We are happy to manufacture your trace heating based on mineral-insulated heating cables according to individual requirements and assemble them with an attached connection cable, as well as screw connection and stranded wire or ceramic power connections. The transition sleeve from the heating section to the connection cable can be made either by soldering or laser welding.

For customer-specific trace heating systems with a low installation height or homogeneous heat development, it is possible to use mineral-insulated sheathed cables with seamless cold ends.

High heat output and robust design: heat tracing systems from ThermoExpert.
