Industrial Electric Heat Tracing Systems
Electrical Heat Tracing
Electric heat tracing compensates for heat loss from piping, tanks, vessels and process equipment. It prevents freezing, maintains defined process temperatures and can provide controlled heat-up. Pro Therm engineers, supplies and installs industrial electric heat tracing systems worldwide.

Freeze protection, temperature maintenance and heat-up
Freeze protection maintains a safe minimum temperature. Process temperature maintenance preserves viscosity, pumpability or product properties. Heat-up duties require additional energy beyond steady-state heat loss to raise the product or equipment to a target temperature within a defined time.
Independent manufacturer selection: we take account of your technical specification, preferred manufacturers and budget. Suitable materials may come from Pro Therm's own range or from eltherm, BARTEC, RAYCHEM/Chemelex and Thermon. We agree the construction, scope and budget with you transparently.
Design starts with the temperature task: preventing freezing, keeping a product pumpable or achieving a specified temperature rise require different heat outputs, control concepts and power supplies. Shutdown, empty pipes and restart conditions are part of the assessment.
The complete system matters
A reliable system consists of more than heating cable. Depending on scope it includes power connections, end terminations, junction boxes, fixing materials, sensors, controllers, protection devices, control panels, documentation and professional installation. A useful enquiry includes pipe and vessel schedules, temperature requirements, insulation data, installation location, available voltage and existing plant drawings. These inputs support a traceable circuit, connection, control and test concept.
A working cable alone does not confirm that the heat tracing system is suitable. Heat must reach the required locations, and insulation must be dry and complete. Design, installation, sensor location and insulation are assessed together. Clear circuit identifiers connect the installation with its test and operating records.
Additional services can be coordinated with the system boundaries. We offer thermal insulation with partner companies and also carry out cabling from our control panels to the power-feed and control boxes where cable routes are already available. Heating, connections and insulation can therefore be requested as a coordinated scope.
Standards reference (checked 14 October 2026): IEC/IEEE 62395-1:2024 and IEC/IEEE 62395-2:2024 are international references for industrial resistance trace heating outside hazardous areas. The project's standards basis is selected for its country, application and agreed scope. DIN EN 60519-10:2014-01 remains the current German standard for safety of industrial and commercial resistance trace heating. Its application is coordinated with the selected heating system and electrical-installation requirements.
Heating cable technologies
Self-regulating cables cover many freeze protection and maintenance duties. Resistance heating cables enable engineered circuits for higher process requirements. Mineral insulated cables are particularly suitable for high temperatures, high power density and robust industrial service.
Hazardous area heat tracing
In hazardous locations, the heater, connection components, temperature limitation, protection concept and installation must match the area classification and application. Project-specific ATEX and IECEx requirements can be integrated from the engineering stage.
Standards reference (checked 14 October 2026): IEC/IEEE 60079-30-1:2025 and IEC/IEEE 60079-30-2:2025 are international references for resistance trace heating in hazardous areas. Germany still lists DIN EN 60079-30-1:2018-04 and DIN EN 60079-30-2:2018-04 as current national editions. Equipment group, permitted EPL, protection concept and evidence for the actual assembly determine suitability.
Where to find the right information
Start with the duty: prevent freezing, maintain a process temperature or heat a product up. The pipe and tank pages address installation geometry. Technology pages explain the characteristics of the different heating cables. Engineering, installation and maintenance describe the services required during a project. This separates the heating task from the equipment and the delivery scope, helping you explore the relevant question before selecting a cable.
