Chromalox SRL | Self-Regulating Trace Heating Cable (Low Temperature – 150°F 65°C)

Trace Heating cable

chromalox srl

Chromalox SRL self-regulating, low temperature trace heating cables provide frost protection to pipework, instrument lines, valves, tanks and heating drums.

SRL trace heating cable has a maximum maintenance temperature rating of 150°F (65°C). Constructed of industrial grade 16 AWG buss wire with a tinned copper braid and overjacketing, SRL ensures safe operation within CSA & FM Division 2 and ATEX Zone 1 (Gas).

Trace Heating Cable Features

• Energy efficient SRL self regulating cables requires less energy as less heat is required
• Simple to install trace heating cable and can be cut to any length (see max circuit length)
• SRL trace heating cables offer low installation costs and require less maintenance, minimising downtime
• Field splices can be performed easily in minutes with no scrap or wasted cold sections
• Heating cables can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps
• Over-temperature is conditions are kept to a minimum with self regulating trace heating cables
• UL listed for use in ordinary areas

TRACE HEATING CABLE Construction

• Twin 16 AWG Copper Buss Wires are able to provide reliable electrical current capability.
• Semiconductive Polymer Core Matrix is the self regulating component of the cable and it’s electrical resistance varies with temperature.
• Water Resistant Polyolefin Jacket is flame retardant and electrically insulates the matric and buss wires and provides resistance to water and some inorganic chemical solutions.
• Tinned Copper Braid that provides additional mechanical protection in any environment, and a positive ground path.
• 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.
