Self-Regulating Heat Trace Cable
for Freeze Protection and Roof &
Gutter De-Icing
Chromalox SRF cable is ideal for keeping metal and plastic pipes
warm in commercial construction, institutional buildings, and some
industrial freeze protection applications, while Chromalox SRF-RG
cable provides reliable freeze protection of roofs and gutters. The
cable automatically adjusts to the appropriate heat output, eliminating
hot spots and making it both energy efficient and cost effective.
Parallel construction makes it easier to install than zone or series types
of cable since it can be cut to length. It can be single overlapped
