REHAU’s snow- and ice-melting systems with Smart Controls efficiently eliminate snow and ice buildup from outdoor surfaces by circulating a heat transfer fluid through REHAU PEXa pipes installed within the SIM area, increasing surface safety while lowering maintenance costs and minimizing environmental impact. The REHAU Smart Controls SIM Module senses everything from slab temperature and snow/ice to boiler supply and return fluid temperatures, while also monitoring the weather forecast. When the control anticipates a storm, it can automatically warm the surface in advance of snow or ice.
