RAYCHEM FHT constant wattage parallel trace heating cables are engineered to deliver freeze protection and maintain process temperatures, handling temperatures up to 230°C and intermittent exposure to 260°C. FHT Parallel Constant Wattage Industrial Heating Cables are available in both 230V and 400V versions, these cables are specifically approved for usage in hazardous areas. Equipped with a fluoropolymer outer jacket (-CT), they offer high resistance against aggressive organics and corrosive substances.
Tailored for pipe and equipment heat-tracing in industrial settings, the FMT and FHT constant wattage parallel circuit heating cables provide a cost-effective solution compared to self-regulating heating cables. While their installation demands more skill and advanced control systems, their unique round geometry allows for exceptional flexibility during installation, enabling bending in various directions.
The fragile heating element of these cables is safeguarded by PTFE insulation tape, eliminating shear stresses during flexing and acting as a shock absorber, ensuring superior protection. Capable of providing frost protection and high power output for process temperature maintenance, these zone parallel heaters are constructed from a heating element enveloping two parallel conductors, with the distance between conductor contact points determining the heating zone length. The parallel design permits on-site customization through cutting to the desired length and termination.
