Chromalox SRP self-regulating heating cable provides safe, reliable heat tracing for process maintenance applications to 230°F (110°C) or freeze protection of pipes / tank with high heat losses. Constructed of industrial grade 16 AWG buss wire with a tinned copper braid and optional overjacketing, SRP ensures operating integrity most hostile industrial environments.

Because SRP is self-regulating, overtemperature conditions are minimized. Chromalox U-Series Connection Kits reduce installation time.

This is a recommendation guide. Chromalox cannot warrant any Electric Heat Trace against failure by sheath degradation if such failure is the result of operating conditions beyond the control of the heater manufacturer. It is the responsibility of the purchaser to make the ultimate choice of sheath material based on knowledge of the chemical composition of the corrosive solution, character of materials entering the solution, and controls which maintains the process.
