DEVIsnow™ 20T - 230 V & 400 V
DEVIsnow™ 20T is a fully screened twin-conductor heating cable designed for snow and ice melting applications on roofs, in gutters, drainpipes, and ground surfaces. The cable features a UV-resistant outer sheath, a round cable profile, and a 2.3 m cold lead.
The round construction supports straightforward installation in a range of outdoor applications. The cable is designed for use in roof and gutter de-icing systems, helping maintain the functionality of exposed outdoor areas during periods of snow and ice.
The heating cable must be used together with a suitable thermostat to help prevent overheating and support controlled energy use.
DEVIsnow™ heating cables are not intended for direct contact with bitumen roofing materials.
The cold lead is supplied with solid conductors and a visible connection point to support electrical installation.
Each cable undergoes production testing, including resistance, high-voltage, and material checks. DEVIsnow™ 20T is supplied with DEVIwarranty™ according to the applicable warranty terms and conditions.
DEVIsnow™ 20T has an Environmental Product Declaration (EPD). An EPD provides quantified environmental information about a product throughout its life cycle based on established assessment methodologies.
