The DEVIpipeguard™ LSZH is a halogen free self-limiting heating cable that is mainly used
for frost protection of pipes. The self-limiting capability of the cable ensures that the output
of the cable increase or decrease according to ambient temperature. The cable will maintain
its functionality even when shortened.
The outer sheath is highly resistant to harsh environmental conditions and corrosion and it also
serves as a protection against mechanical influences. All self-limiting heating cables must be
over-temperature protected by a thermostat, as the output will decrease, but never be zero.
The cables are not approved for use in drinking water.
