RAYCHEM FMT constant wattage parallel heat tracing cables are designed to provide freeze protection and process temperature maintenance up to 150°C, withstanding intermittent exposure to 200°C and routine steam purges. FMT Industrial Heating Cables operate at 230V with an FEP outer jacket and are specifically approved for use in hazardous areas.
Primarily tailored for pipe and equipment heat-tracing in industrial settings, the FMT and FHT constant wattage parallel circuit heating cables offer a cost-effective alternative to self-regulating heating cables. While installation requires more skill and advanced control systems, the round geometry of these cables enhances flexibility during installation, allowing bending in multiple directions. The heating element, the most delicate part of the cable, is safeguarded by PTFE insulation tape, mitigating shear stresses during flexing and acting as a shock absorber for enhanced protection.
Ideal for frost protection and process temperature maintenance requiring high power output, these cables feature zone parallel heaters constructed from a heating element wrapped around two parallel conductors. Their parallel construction allows for on-site customization by cutting to the required length and termination.
