Heat Tracing for Fire Protection SystemsRecent changes in many city fire codes have required that heating cables used for freeze protection of fire protection system piping carry a special UL listing specific to fire protection system piping. Company has obtained this UL listing for Models SRL-C, SRL-CR, SRL-CT, SRM/E-C, SRM/E-CT, SRF-C and SRF-CR heat trace cables. The self-regulating heating cables utilize a special semiconductive polymer core matrix bonded to the conductors, which minimizes the risk of an overtemperature condition.
