Advantage of Composite Ventilation Pipe

1. To reduce the cooling load, it uses polyurethane compact honeycomb structural sheet with excellent thermal insulation performance to process and shape. The design of each segment air duct segment connection can ensure its tight connection and no leakage.

2. By virtue of its lightweight and flange connection system beyond imagination, the combined moulding air duct system saves installation time greatly compared with the traditional metal sheet air duct system.

3. The operation and installation of sheet metal air duct in the industry are expensive. At the same time, sheet metal air duct must be equipped with thermal insulation layer. The combined forming air duct system is much more economical.

4. The ultra-light weight and easy disassembly and assembly of the composite air duct system make its cleaning very easy. The aluminium foil flooring on its surface ensures high hygienic standards.

5. Compared with the metal duct with heat preservation, it is 4-5 times lighter.

Energy saving model

1. Excellent thermal insulation performance (NT-I) composite air duct directly compounded thermal insulation materials, thermal resistance is far greater than the same thickness of traditional air duct insulation materials, do not need a second thermal insulation. The small thermal conductivity of air duct can not only avoid the condensation of water and gas in air handling system, but also reduce the energy loss of air duct wall. It has excellent thermal insulation performance and can effectively reduce the operation cost of HVAC system.

2. Good sealing performance (NT-I) composite air ducts are all made of glued structure, which can not be connected in blue, thus greatly improving the sealing performance of air ducts. Compared with the iron duct, it reduces the air leakage of bite and flange, effectively reduces the air leakage rate of the duct, and improves the air conveying efficiency. The leakage rate of composite duct is only 10% of that of iron duct.

3. The NT-I composite air duct sheet is manufactured by mechanization with smooth and flat surface, small friction coefficient and low wind resistance. The absolute roughness of the air duct surface is 0.2mm. Compared with the iron duct, the air flow efficiency is obviously superior, which can ensure that the air flow passes through with the lowest energy consumption.

Environmental protection model

1. As a new type of green building material, NT-I composite air duct with high quality has taken effective environmental protection measures in terms of raw materials, process formulation, energy consumption in production process and additional revenue of discharged products according to the idea of LCA.

No matter in the process of production, manufacture, installation or use, air ducts do not produce substances that pollute the environment. Formaldehyde emission was less than 0.1 mg/L. Even when the duct is burned, the smoke generated by the duct does not contain toxic substances and is harmless to human body. The product quality is stable and reliable. It is a new generation of high quality environmental protection products. The product surface is covered with high strength protective film, which effectively solves the secondary pollution caused by field construction.

2. Improving indoor air quality (NT-I) Composite duct is coated with anti-bacterial and anti-mildew isolation medium, which effectively inhibits the growth and reproduction of various microorganisms in duct, avoids air pollution in duct, does not rust, mildew, does not produce bacteria, fungi, dust and fibers, odorless, and does not produce granular or odorous pollution. Dyes or biological aerosols ensure indoor air quality.

3. Noise reduction, creating a quiet space (NT-I) composite air duct has good sound insulation performance. Its insulation material has both shock absorption and sound absorption performance. It can reduce the noise caused by air flutter and mechanical operation, and completely solve the noise caused by shrinkage and expansion of tin air duct. Moreover, it can prevent sound transmission through air ducts between rooms and ensure the privacy of each room.
