HVAC Duct Fabrication: Precision Solutions for Global Standards

Precision-engineered duct machines and welding solutions transform sheet metal into standardized, high-quality HVAC systems globally.

For over 20 years, HYRUN Technology has engineered advanced duct processing systems that redefine efficiency in HVAC fabrication. Our spiral duct machines produce SMACNA-compliant round ducts at 20% higher throughput than conventional methods, while hydraulic elbow machines achieve precise 30°–180° bends with ≤0.5mm tolerance. TDF/TDC flange systems automate lock-forming and corner notching for rectangular ducts, reducing labor costs by 40% and ensuring airtight DW/144 compliance.

Intelligent welding solutions like angle steel flange automatic welders eliminate manual grinding, accelerating structural duct assembly by 50%. Integrated IoT capabilities in duct production lines enable real-time monitoring of material thickness (0.4–1.5mm galvanized/SS) and pressure settings, minimizing scrap rates to under 2%.

Beyond traditional ductwork, our laser cutting and high-precision bending equipment fabricate custom dampers, diffusers, and plenums with ±0.1mm accuracy. This versatility supports BIM-driven projects requiring complex geometries for high-rise HVAC installations.

HYRUN delivers cutting-edge duct fabrication machinery that addresses:

Precision: CNC-controlled forming for ±0.1 mm tolerance in complex geometries (e.g., finned-tube heat exchangers, micro-perforated silencers)10.

Scalability: Equipment supporting high-volume production (up to 8,000 m³/h capacity) for automotive OEMs and customizable solutions for commercial retrofits 38.

Efficiency: Integration of EC motor technology reduces energy use by 30–50% compared to traditional systems 4.
