Self Regulating Trace Heating | Eltherm ELSR-SH ATEX Trace Heating Cable (Up to 250 Degrees Celsius)

Product Overview

Self Regulating Trace Heating

ATEX Trace Heating Cable | Eltherm ELSR-SH

The Eltherm ELSR-SH high temperature self-regulating trace heating 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-SH trace heating cables are suitable for Zone 1 and Zone 2 hazardous areas – and have a temperature Class of T3/T2.

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 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.
