High-Temp Flexible Heating Duct | -45°C to 300°C & Up to 1200°C | Industrial HVAC & Ventilation
Our Flexible Heating Duct is engineered for high-efficiency, reliable thermal air transfer in demanding industrial, commercial, and temporary heating applications. Designed to withstand extreme temperatures from -45°C to 300°C (with optional grades up to 1200°C), this duct ensures safe, continuous operation in harsh environments. Constructed with a robust three-layer composite material—including a reinforced middle layer for superior insulation—it delivers exceptional thermal retention, durability, and flexibility.
Available in diameters from 80mm to 1000mm and standard lengths of 3.6m or 7.6m, this duct is compatible with a wide range of heating, ventilation, and exhaust systems. Its external spiral steel wire guard provides outstanding abrasion resistance, allowing for ground dragging without wear, while the internal structure resists vibration, chemicals, and physical stress. Whether for permanent installation or mobile heating solutions, this duct offers a cost-effective, long-lasting performance upgrade.
Flexible Heating Duct
The Flexible Heating Duct is a specialty ductwork solution crafted to transport hot air, warm gases, and exhaust fumes with minimal heat loss and maximum durability. It serves as a critical component in systems where temperature resilience, flexibility, and strength are non-negotiable. Made from high-grade materials including a glass fiber layer, it is inherently flame-retardant, water-resistant, and capable of handling abrasive particulates like dust and fibers.
