Heating cables
Self-regulating heating cable Thermon FLX
FLX self-regulating heating cables are designed to provide freeze protection and temperature maintenance to metallic and nonmetallic pipes, tanks and equipment. FLX heating cables are rated for heat outputs of 3, 5, 8 and 10 watts/foot at 50° F (10, 16, 26 and 33 watts/meter at 10°C) when powered at 110 to 120 Vac or 208 to 277 Vac. FLX is a proven, simple, practical solution for both metal and plastic pipes.
FLX self-regulating cables are protected by a tinned copper braid and a polyolefin outer jacket to provide grounding and additional mechanical protection for the cable. An optional fluoropolymer outer jacket is available if additional environmental protection is required. Heat tracing users expect quality products and services from a reputable manufacturer. Thermon exceeds these ex-pectations by operating under the ISO 9001 standard for quality.
Whether the application is a small project or a complex network of piping and equip-ment, designing an electric heat traced freeze protection system is easy with FLX self-regulating cables. The step-by-step design guide leads the reader through determining the heating requirements and number of circuits required to establish a bill of materials.With parallel circuitry, FLX cables do not require piping dimensions and can be cut to length in the field. Heat tracing circuits for field-routed piping can be quickly and easily designed on site.
Features of Thermon-FLX
FLX is installed directly on metallic or nonmetallic piping under conventional thermal insulation with ordinary hand tools. Kits for power connectionm end termination and splicing, plus other accessories, are designed for quick and easy installation.
