Self Regulating Freeze Protection

Chromalox SRF cable is ideal for keeping metal and plastic pipes warm in commercial construction, institutional buildings and some industrial freeze protection applications. SRF cable is constructed of a self-regulating polymer core that varies its output along its entire length, saving energy and eliminating hot spots along the pipe. Parallel construction makes it easier to install than zone or series types of cable since it can be cut-to-length at any point on the pipe. It can be single overlapped without overheating the cable.

Another use is Self Regulating Roof & Gutter Protection.  It is easy to apply SRF-RG following the provided instruction sheets and utilizing the required accessory kits. It can be cut-tolength and single overlapped. Simply trace the gutter or roof and energize the cable when precipitation is expected. From that point on, SRF-RG will rapidly increase its output when in contact with snow or ice, providing maximum melting power. When the roof and gutters are clear of snow and ice, the SRF-RG cable will regulate its output and save energy.

Features

• Energy efficient, self-regulating SRF uses less energy when less heat is required.
• Easy to install, SRF can be cut to any length (up to max. circuit length) in the field.
• Field splices can be performed easily in minutes with no scrap or wasted cold sections.
• SRF can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps.
• Because SRF is self-regulating, overtemperature conditions are minimized.
