Electrical surface snow melting system.
For melting surface snow.
The Raychem ground heating solution prevents snow and ice formation which can present a major problem causing accidents and delays. The Raychem range of products has been specifically designed to meet the requirements of commercial, industrial, and residential applications. Whether installed into concrete, sand, or asphalt, a Raychem system exists to provide a fast, reliable and easy install solution.
Each Raychem heating solution is complete with a Smart control and monitoring unit, providing useful user data and excellent energy efficient performance. The multi-sensor control and monitoring device (VIA-DU-20) is compatible with all ramp snow melting solutions. Approvals: VDE and CE marked.
