The nVent RAYCHEM RIM system is North America’s leading, high performance, aesthetically pleasing, concealed snow melting and de-icing solution, powered by nVent RAYCHEM self-regulating cable technology.

A typical roof and gutter de-icing system uses a visible zigzag of self-regulating heating cable to melt snow and ice along the roof edge. This method is effective but for many projects, the visible electrical cable can be seen as a drawback.

The RIM system conceals the heating cable and an extruded aluminum base beneath a color-matched, protective metal plate, that not only improves the aesthetics, it enhances the system’s ability to evenly distribute heat throughout the treated area.
