Three Good Reasons for Choosing the Raychem System

The 4 ground heating systems from Raychem are designed to be robust during installation and provide reliable ice and snow protection over the installed surface. Whilst the EM2-XR system is available as a cut-to-length and on-site terminated product, the entire range is also available in factory supplied, pre-terminated units for increased peace of mind.

Flexible

The Raychem systems are specifically designed to provide flexibility in design and in installation. The range has been developed to facilitate:

• Easy design for complex heated areas: ramps or access ways with irregular shapes.
• Easy selection to meet the proposed ramp/ground profile. Whether in a sand/cement mix or directly under asphalt.
• In fast installation formats to reduce installation time on site.

Energy Efficient

The “Smart” Raychem control unit can save up to 80% of energy over standard “temperature only” activated systems. The new VIA-DU-20 electronic control unit features a combined moisture & temperature sensor as well as an ambient temperature sensor, which work together to only activate the ramp heating when ice and snow conditions exist. Whenever the sensor measures a specific minimum temperature in combination with a high moisture value, it will trigger the heating cable to raise the temperature of the outside surface and thus prevent ice formation and snow accumulation.

Thanks to this combined sensing operation, the VIA-DU-20 reduces the cost of operating the snow melting system by up to 80%. Where conventional systems start working when temperature falls below the set point, even without precipitation, the smart VIA-DU-20 control remains off until ice or snow is present.
