Product Overview

Raychem ElectroMelt EM2-XR is a rugged, self-regulating electric heating cable designed for snow melting and ice prevention in concrete pavement applications. It helps keep outdoor surfaces clear by generating heat in response to changing pavement temperatures, providing a practical solution for cold-weather environments.

Designed for installation directly within concrete, ElectroMelt is suitable for applications such as vehicle ramps, loading bays, external stairs, walkways and access roads. Its self-regulating conductive polymer core automatically adjusts heating output along the cable according to local temperature conditions.

The cable features parallel electrical circuitry, allowing it to be cut to the required length within the manufacturer's specified circuit limits. Its robust construction includes a conductive heating core, modified polyolefin insulation, a tinned-copper grounding braid and a modified polyolefin outer jacket for demanding pavement installations.

Technical Specifications

Applications

Raychem ElectroMelt EM2-XR is designed for surface snow melting and anti-icing systems in suitable outdoor concrete installations, including:

• Vehicle ramps and sloped driveways.
• Commercial loading bays and delivery areas.
• External stairs and entrance steps.
• Pedestrian walkways and outdoor access paths.
• Building entrances and access routes.
• Parking area entrances and selected concrete pavement sections.
• Commercial and industrial outdoor circulation areas.
• Other compatible concrete snow-melting applications approved by the manufacturer.

Cable Construction and Operating Principle

The ElectroMelt EM2-XR heating cable uses a crosslinked conductive polymer core extruded between two parallel 14 AWG nickel-plated copper bus wires. When electrical power is applied, the conductive core generates heat and adjusts its power output in response to the local concrete pavement temperature.

The parallel circuit design allows the cable to be cut to length within the permitted circuit limits. A modified polyolefin inner jacket provides electrical insulation, while a heavy tinned-copper braid and modified polyolefin outer jacket provide the specified protective construction for installation in concrete.

The cable is designed to help prevent snow and ice buildup without localized burnout caused by overlap under the manufacturer's specified installation conditions. Proper system design, cable spacing, concrete placement, electrical connections and control strategy remain essential for reliable performance.

Installation and Electrical Protection

ElectroMelt must be installed as part of a properly designed surface snow-melting and anti-icing system. Cable layout, spacing, circuit length, supply voltage and circuit-breaker ratings must be determined according to the manufacturer's design documentation and the specific site requirements.

• Use approved Raychem ElectroMelt connection and termination kits.
• Follow the specified installation method for concrete pavement applications.
• Observe the minimum installation temperature and minimum bend radius.
• Provide the required ground-fault equipment protection for every heating cable branch circuit.
• Verify circuit lengths against the applicable supply voltage, breaker rating and startup temperature.
• Ensure electrical installation complies with applicable local codes and regulations.
• Use qualified electrical personnel for system installation, testing and commissioning.
