Self-regulating heating cable ELCHEM RÄNNI 18/36

ELCHEM RÄNNI is a high-quality UV-resistant cable intended for the de-icing of rainwater pipes. The cable releases a significant amount of power when exposed to snow and icy water (36 W/m @ 0°C). When the ice has melted and the cable is dry, the heating effect is reduced by half, which provides significant energy savings. The cables are delivered in reels or cut into a loop of a required length. In the latter case, the cable is equipped with cold ends of a desired length and the ends are terminated.

If the site requires and armoured cable, the PST 20 de-icing cable must be used instead.
