Chromalox SRM/E self-regulating heating cable provides safe, reliable heat tracing for process temperature maintenance and freeze protection of pipes, valves, tanks and similar applications. Constructed of industrial grade 16 AWG buss wire with metal braid and optional overjacketing, SRM/E ensures operating integrity in most hostile industrial environments. The 420°F (215°C) maximum exposure temperature rating allows steam cleaning of process equipment with up to 300 psig steam.

WARNING — A ground fault protection device is required by NEC to minimize the danger of fire if the heating cable is damaged or improperly installed. A minimum trip level of 30mA is recommended to minimize nuisance tripping.

Features

Energy efficient, self-regulating SRM/E uses less energy when less heat is required.
Easy to install, SRM/E 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.
With lower installed cost than steam tracing, SRM/E features less maintenance expense and downtime.
SRM/E can be overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps.
Because SRM/E is self-regulating, overtemperature conditions are minimized.
Chromalox termination, splice, tee and end seal kits reduce installation time.

CR- TPR overjacket over braid for protection against certain inorganic chemical solutions

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.
