NUOENWEI Single-Layer High-Temperature Resistant Fabric-Reinforced Ducting | -45°C to 300°C

Continuous Operation from -45°C to +300°C. This duct is built to perform across one of the widest thermal windows in flexible ducting, handling both sub-zero environments and sustained high-temperature airflow without structural degradation. For applications that demand more, NUOENWEI can supply upgraded grades rated to 400°C, 600°C, or 1200°C.

Iron Clamp Cloth Construction for Reliable Wall Integrity. The duct body is formed using an iron clamp cloth method, where the fabric edge is mechanically crimped and interlocked around the steel wire helix. This creates a strong, mechanically bonded seam structure without relying on adhesives, glue strips, stitching, or heat-fusion processes. The result is a duct wall that holds together under continuous flexing, vibration, and thermal cycling.

Smooth Internal Bore for Efficient Airflow. Because the steel wire reinforcement is positioned externally, the internal surface of the duct remains entirely smooth and unobstructed. This minimises airflow resistance, prevents dust and particulate buildup inside the duct, and ensures efficient delivery of heated air — particularly important in heater ducting and drying applications where airflow performance directly affects energy efficiency.

High Flexibility with Excellent Compressibility. Despite its high-temperature capability, the duct remains highly flexible and can be bent, routed through confined spaces, and compressed for storage and transport. This makes it practical for temporary installations, portable heater systems, and job sites where rapid deployment and pack-down are required. Fabric-reinforced ducts of this type are widely used precisely because they combine flexibility with compressibility.

Lightweight and Easy to Handle. The single-layer construction keeps the duct light enough for one or two workers to position and install without lifting equipment. This reduces installation time and labour costs, especially in overhead runs or multi-level routing.

Customisable Diameters and Lengths. Available in inner diameters from 100mm to 1000mm, with custom lengths to match specific project requirements. This makes the duct suitable for everything from small-diameter fume extraction lines to large-scale hot air distribution systems.

Durable External Steel Wire Helix. The helical steel wire provides crush resistance, maintains the duct's shape under negative pressure, and protects the fabric wall from external abrasion when the duct is dragged across floors or rough surfaces.

Portable and Temporary Heater Ducting. Construction sites, event tents, and temporary work areas rely on portable indirect-fired heaters to maintain comfortable or safe working temperatures. This duct connects directly to heater outlets to distribute heated air efficiently across the space. Its -45°C low-end capability means it performs reliably even in cold-weather deployments.

Industrial Hot Air Conveyance. Manufacturing processes that require controlled hot air delivery — such as drying ovens, curing systems, and thermal processing lines — use flexible ducting to route heated air from the source to the point of application. The smooth bore and high-temperature rating make this duct well-suited for continuous operation in such systems. Typical heater duct applications include air circulation for environmental test chambers and industrial drying systems.

Fume and Exhaust Extraction. Welding stations, engine test cells, and industrial processes that generate hot fumes require extraction ducting capable of handling elevated exhaust temperatures. This duct is suitable for welding gas and fume aspiration, engine exhaust fume extraction, and general industrial fume removal.

Foundry, Furnace, and Metallurgical Operations. High-temperature extraction systems in foundries, smelting operations, ceramics plants, and steelworks frequently require flexible ducting that can withstand radiant heat and hot gas streams. Applications in these environments commonly include high-temperature extraction from ovens, furnaces, and smelting equipment.

Drying and Dehumidification Systems. Cement drying, grain drying, and industrial dehumidification systems use heated air ducting to direct warm, dry air into enclosed spaces or processing equipment. The high-temperature fabric-reinforced construction is designed for this type of continuous hot-air delivery.

Chemical Plant Ventilation. Chemical processing facilities generate corrosive vapours and elevated-temperature fumes that require dedicated extraction ducting. With appropriate material selection, this duct can handle chemical fume extraction and vapour removal in industrial environments.

Aircraft Ground Support and Marine Ventilation. Aircraft cabin ventilation during ground operations and marine air handling systems both benefit from lightweight, flexible, high-temperature ducting that can be quickly deployed and routed around obstacles.

HVAC Systems in Demanding Conditions. Standard HVAC systems in industrial facilities often encounter higher-than-normal supply air temperatures. This duct provides a flexible connection solution for HVAC systems operating under demanding thermal conditions, where standard flexible ducting may not be rated for the application.
