SELF-REGULATING TRACE
HEATERS
Self-regulating heating cables
eltherm is a global provider of electrical heat tracing. Our wide product range includes self-regulating heating cables, series or parallel resistance trace heaters, heating mats and heating jackets, mineral-insulated trace heaters and heated hoses. Whether as freeze prevention to keep your pipeline or medium frost-free or for temperature maintenance - we have got the right solution for your application. With our ELSR-series (ELtherm-Self-Regulating) we offer you a self-regulating heating cable for different ranges and temperature classes.
- Low Temperature: Up to 80 °C
- Medium Temperature: Up to 110 °C
- High Temperature: Up to 250 °C
A self-regulating heat trace is applied in a wide range of industries. From heating a sugar silo to prevent condensation, to gutter heating – we will find a individual solution for your requirements. A self-regulating trace heating is planned individually and tailor-made for you by our engineers.
Benefits
- Self-regulating with adaptable output
- Choose between different temperature ranges (low, medium and high temperature)
- Demand-orientated output grading
- High chemical resistance
- No temperature limitation required (important in Hazardous Areas)
- Easy to install
- Can be cut to length off the roll
- Connection by plug-in connectors

What is a self-regulating heating cable and how does it work?
Self-limiting heating cables consist of two parallel bus wires embedded in a heating matrix doped with carbon particles. When the temperature rises in operation, molecular expansion increases the distance between the carbon particles. The resistance increases and output drops. When temperatures fall, this process is reversed and output increases. Due to this process, the heat is regulated and overheating of the heat tracing is prevented. This eliminates the need for regulation with additional accessories. Moreover, selected ELSR heating cables are approved for use in hazardous areas and we offer a separate product range for the USA and Canada.
Where a self-limiting heating cable can be used
The ELSR (eltherm-self-regulating) trace heater is used for freeze prevention and temperature maintenance on vessels, pipes, valves, etc. It may be immersed in fluids. Provided with a chemical-resistant protective jacket* (see version "BOT"), pipe heat tracing is not only possible in a water pipe, but is also suitable for aggressive environments. Detailed information on nominal voltage, bending radius or ambient temperatures can be found on the detailed pages of the products. There you will also find further documents such as data sheets and approvals or check out our youtube channel for assembly instructions.
