Self Regulating Trace Heating | Eltherm ELSR-R Trace Heating Cable (Up to 65 Degrees Celsius)

Product Overview

Self Regulating Trace Heating

Trace Heating Cable | Eltherm ELSR-R

Eltherm ELSR-R is a versatile self-regulating trace heating cable provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 65° Celsius. The ELSR-R heater cable has a round design and is ideal for protecting the doors and seals of refrigerating chambers against frost and is often used in cooling water lines of breweries and drinks manufacturers.

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-R is suitable for use in various industrial applications where maintaining consistent temperatures is critical for process integrity and safety including:

• Freeze prevention
• Special solutions
• Doors and seals of refrigerating chambers
• Cooling water lines of breweries and drink manufacturers

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.
