Product Overview

Self Regulating heat tracing

ATEX Heat Tracing Cable | Eltherm ELSR-H

Eltherm ELSR-H is a self-regulating heat tracing cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 210° Celsius – with IECEx and ATEX Certification Eltherm ELSR-H heat tracing cables are suitable for Zone 1 and Zone 2 hazardous areas.

The ELSR-H heating cable is designed to provide safe and reliable heat tracing for pipes and vessels in hazardous areas, helping to prevent freezing and maintain the temperature of critical processes. It is available in a range of power outputs and can be easily installed using a variety of fixing methods. Suitable for a range of different applications including:

• Valves, pumps
• Silos, vessels, tanks
• 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.
