DurkeeSox Fabric air dispersion system(fabric air duct), An innovative product in HVAC industry At the beginning of the 60s, HVAC engineers tried to utilize cotton textile to make fabric air dispersion ductworks in food processing refrigeration industry, to deliver larger cooling capacity and lower airflow velocity. They were called Fabric ductwork or Textile ducts. After decades of material and fabric technology innovation, more specialty fabrics are introduced to build air dispersion ductworks. Fabric ductwork ( or textile ducts) has gained wide acceptance from the market. DurkeeSox Manufacture facility in China are certified under multiple internationally recognized QA programs, including ISO9001:2000, ISO14001, ISO18000 by AQA. The standard large space airflow simulation test lab equipped with CFD design and simulation software is one of the most advanced research and test lab in the world. State of art production lines in DuekeeSox with the most advanced laser cutting equipments, and the most rigorous QC, ensure all the products meet the most stringent code requirements. They surpasses many regional code regulations on fire safety, durability, stable permeability, pressure resistance, tension resistance and anti-microbe performance.
