Chromalox SRF 8-2C frost protection trace heating cables provide self-regulating frost protection to institutional buildings and freeze protection applications up to 185º F – with UL listing and CSA certification for fire protection system piping and ordinary areas.

Energy efficient SRF frost protection cables requires less energy as less heat is required
Simple to install cable and can be cut to any length (see max circuit length)
Can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps
Field splices can be performed easily in minutes with no scrap or wasted cold sections
Chromalox termination, splice, tee and end seal kits reduce installation time

A Twin 16 AWG Copper Buss Wires are able to provide reliable electrical current capability.

B Semiconductive Polymer Core Matrix is the ‘self regulating component of the cable and it’s electrical resistance varies with temperature.

C Fluoropolymer Jacket is flame retardant and electrically insulates the matric and buss wires and provides corrosion resistance.

D Tinned Copper Braid that provides additional mechanical protection in any environment, and a positive ground path.

E High Temperature Fluoropolymer or TPR Overjacket (optional) is a corrosion resistant, flame retardant overjacket is highly effective in many environments. TPR coatings protect against certain inorganic chemical solutions.
