Eltherm ELSR-FHP is a versatile self-regulating heat tracing cable that provides process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 110° Celsius – with IECEx and ATEX Certification Eltherm ELSR-N heat tracing cables are suitable for Zone 1 and Zone 2 hazardous areas.
The self-regulating 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-FHP is suitable for use in various industrial applications where maintaining consistent temperatures is critical for process integrity and safety including:
Our Team of Trained Sales Engineers are available to advise and support your ATEX heat tracing 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-FHP self-regulating trace heating wattages per metre at 5°C – 23, and 38 watts.
Eltherm ELSR-FHP self-regulating heating cables are available in the BO design. The BO version of the ELSR-FHP heating cable has a protective tin-plated copper braid to adapt to low-temperatures and medium temperature applications.
Heat Tracing Classification:
Hazardous Area Certification:
Temperature Class: T5
Eltherm ELSR-FHP heating cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 110° Celsius – with IECEx and ATEX Certification Eltherm ELSR-N trace heating cables are suitable for Zone 1 and Zone 2 hazardous areas. 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-FHP 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.
