Chromalox SRM/E Self-Regulating Trace Heating Cable (Medium Temperature – 302°F 150°C)

Frost Protection Trace Heating Cables

Trace Heating

Chromalox SRM/E self-regulating trace heating cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums up to 150º Celsius. They are Factory Mutual (FM) Approved, UL Listed, and CSA certified for ordinary areas. ATEX, IECEx, FM, and CSA Approved for hazardous areas when.

Trace Heating Cable Features

• Chromalox SRM/E trace heating cables are energy efficient as they use less energy when less heat is required
• The simple to install heating cable can be cut to any length while in the field (see max circuit length)
• SRM/E trace heating cables offer low installation costs and require less maintenance minimising downtime
• Heating cables can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps
• The risk of overtemperature is minimised with self regulating trace heating cables
• Chromalox cable termination, splice, tee and end seal kits further reduce installation time

Chromalox Frost Protection Cable

Construction

• 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 matrix 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 Overjacket (optional) is a corrosion resistant, flame retardant overjacket is highly effective in many environments.
