ATEX Heat Tracing Cable | Eltherm ELSR-SHH
The Eltherm ELSR-SHH high temperature self-regulating heat tracing cables  is designed for temperature maintenance in industrial processes and applications in hazardous areas – and is suitable for use up to 250 °C . The high chemical resistance allows the cables to be installed in environments with exposure to aggressive influences. With IECEx and ATEX Certification, Eltherm ELSR-SHH Heat Tracing cables are suitable for Zone 1 and Zone 2 hazardous areas – and have a temperature Class of T3/T2.
The ELSR-SHH is now available with certificate according to standard EN 60079-30-1:2017 .
The self-regulating trace heating cable provides frost protection and temperature maintenance to pipework, silos vessels ,tanks, valves and pumps. Suitable for use in the following industries:
- Chemistry and Petrochemistry
- Oil and Gas Industry
- Power plants
- Water and sanitation utilities
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.
