Data Sheet

DEVIiceguard™ 18 (B)

The DEVIiceguard™ is a self-limiting parallel heating cable that is used for ice and snow melting on roofs and in gutters and downpipes.

DEVIiceguard™ heating cables should not be in direct contact with bitumen roofs. The self-limiting capability of the cable ensures that the output of the cable increase or

decrease according to ambient temperature. The heating cable is ﬂexible and easy to install as it can be cut to length at site and installed

directly on to the roof and gutter system. All self-limiting heating cables must be overtemperature protected by a thermostat, as the output will decrease, but never be zero, and be protected by a RCD with a maximum trip current of 30 mA.

Beneﬁts:

• Easy to install

• Cut to length on site

Standard compliance:

• EN 62395-1: 2013
