Trace heaters are the universal answer to the most diverse requirements for heating or warming media in pipes, vessels, as well as individual construction solutions. They can be installed flexibly and enable the transfer of high heat output. At the same time, trace heating systems are exposed to strong mechanical requirements and a wide variety 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 core (heating wire), which is shielded against the metal sheath with magnesium oxide as insulator. The outer diameter of the sheathed cable and the nature and thickness of the inner core have a significant influence on the resistance and thus on the heat output of the trace heating. The selection of the 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, depending on the design, can generate temperatures of up to 1000°C at the heating conductor. Their closed metal jacket protects the trace heating from the penetration of moisture, gases or other media.
We will be pleased to manufacture your trace heating based on mineral-insulated heating cables according to individual requirements and assemble them with attached connection cable, as well as screw connection and stranded wire or ceramic current connections. The transition sleeve from the heating element to the connecting cable can be soldered or laser welded.
In the case of customer-specific trace heating systems with a low installation height or homogeneous heat development, it is possible to design them with mineral-insulated sheathed cables with transitionless cold ends.
High heat output and robust construction: heat tracing systems from ThermoExpert.
We offer the transition optionally brazed or also with laser welding.
