Chromalox SRL Heat Trace Cables – Trace Heating
Chromalox SRL self-regulating trace heating cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and heating drums up to 65º Celsius – with ATEX, IECEx, CSA, FM, GOST and UL certification Chromalox SRL heat trace cables are suitable for Zone 1 and Zone 2 hazardous areas.
Trace Heating Cable Features
Chromalox SRL Self-Regulating
- Energy efficient SRL self regulating cables requires less energy as less heat is required
- Simple to install 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
- Can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps
- Overtemperature is virtually impossible with self regulating trace heater cables
- UL listed for use on fire protection system piping

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.
