PU HVAC Duct

PU HVAC Duct (Polyurethane HVAC duct) takes high-quality polyurethane as the core base material and adopts a double-layer composite structure design. The inner layer is a smooth polyurethane film, and the outer layer is supplemented with reinforced fiber cloth, which combines flexibility and structural stability.

Compared with traditional metal air ducts, its material has a significant lightweight feature, with a unit weight of only 1/5 of that of galvanized steel plate air ducts. This can greatly reduce the load-bearing pressure on the building ceiling, while avoiding the problems of easy rusting and corrosion of metal materials. Its service life is extended to more than 15 years, reducing the cost of later replacement.

The product is equipped with a highly efficient insulation layer, with a thermal conductivity as low as 0.022W/(m · K), far exceeding the industry's conventional standards. It can effectively reduce energy loss during the cold and heat transportation process of the air conditioning system.

Under the cooling conditions in summer, the loss of cooling capacity can be reduced by more than 30%. During winter heating, the insulation effect is stable, avoiding condensation on pipes. There is no need to wrap additional insulation materials, simplifying the construction process while helping buildings achieve low-carbon and energy-saving goals. Long-term use can significantly reduce the energy consumption of air conditioning system operation. ​
