Ramp heating Cables & Systems
Eltherm ELSR-Ramp Cable
The ELSR-Ramp is a heating cable manufactured by Eltherm that is designed for outdoor applications to prevent snow and ice accumulation on ramps and walkways.
These self-regulating cables are designed to automatically adjust their heat output based on the surrounding temperature. When temperatures drop, the cables increase heat production, and when temperatures rise, the heat output decreases.
The ELSR-Ramp heat tracing cable is specifically designed for applications in ramps and walkways, where the cables need to be flexible, durable, and capable of withstanding heavy foot traffic. These ramp heating cables are typically installed underneath the surface of the ramp or walkway and can be connected to a control system that monitors and regulates the heat output.
The primary purpose of using ramp heater ELSR cables is to prevent the formation of ice and accumulation of snow, thereby ensuring safe and clear paths for pedestrians. This helps to prevent slip and fall accidents, especially in areas with cold climates or high precipitation.

ELSR Heating Cable : Frost Protection & Process Temperature Maintenance for Ramps
Snow & Ice Melting for Ramps | Heat Tracing Cables & Systems – Thorne & Derrick can design and supply outdoor ice and snow melting systems where the cables are being fitted into tarmac, concrete and under block paving constructions where the cables must be of durable construction to withstand building site environments.
Ramp heating technical Benefits
- Highly robust ramp heating cable
- Suited to complex installation conditions
- Flexible mounting for the heating of ramps, stairs and walkways
- Radially and longitudinally waterproof to suit all weather conditions
- Outer jacket is strongly grouted with protective braid
Also by using heating for ramps in areas prone to weather conditions, property owners can enhance safety and minimise liability – this can improve accessibility during the cold seasons and prolonged periods of sub-zero temperatures leading to the formation of dangerous levels of ice and snow accumulation.
