Trace Heating Cable | Eltherm ELSR-M

Eltherm ELSR-M is a versatile self-regulating trace heating cable that provides process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 65° Celsius.

The self-regulating trace heating technology allows the heating cable to increase or decrease its heat output based on the ambient temperature, providing energy-efficient operation and preventing overheating. ELSR-M is suitable for use in various industrial applications where maintaining consistent temperatures is critical for process integrity and safety including:

  • Heat tracing on pipes, pumps and valves
  • Food processing industry
  • Automotive
  • Heating of tube bundle cables for water analysis
  • Heat tracing on vessels

Our Team of Trained Sales Engineers are available to advise and support your trace heating enquiries – this includes design and supply of complex multi-kilometre, major-project systems to custom heat trace cable kits for the protection of winterisation against plant and factory facilities.

Eltherm ELSR-M Trace HEAting CABLE – SPECIFICATION

ELSR- M

  1. Bus wire – nickel plated copper, 0.62 mm²
  2. Self-regulating heating element
  3. Insulation
  4. Protective braid – (Cu, tin plated)
  5. Outer jacket – TPE-O
  6. Protective conductor connection – see 4 or Cu, tin plated with aluminium foil

Eltherm ELSR-M self-regulating heating cables are available in two cable designs. The BO version of the ELSR-M heating cable has a protective tin-plated copper braid for all low – temperature and medium – temperature applications.

  • BO: Protective braid and a thermoplastic outer jacket
  • AO: Aluminium foil and a thermoplastic outer jacket

Eltherm ELSR- M BENEFITS

  • Four nominal outputs
  • UV-resistant
  • Moisture proof
  • Highly durable
  • Efficient heat distribution
  • Junction box for pipe mounting

ELSR-M-AO ELSR-M-BO

Eltherm ELSR- M heating cables provide temperature maintenance and frost protection to pipework and mechanical services in all industries – typical applications include heating process pipework, instrument lines and storage tanks to maintain viscosity or prevent frost damage as an integral work-task of plant Winterisation.

Eltherm ELSR-M cables utilise cold-applied installation components to complete the trace heating system – no requirement for “hot-working” permit applications in potentially explosive atmospheres, including Zone 1 and Zone 2 hazardous areas.
