Products Description of PIR Air Duct Board

PIR Air Duct Board is composed of polyisocyanurate (PIR) insulation foam as the core material, with different surface layer materials compounded on both sides. Common surface layers include 60 or 80 micron embossed or smooth aluminum foil, 150-200 micron aluminum plates, pre-coated galvanized steel plates, etc.

Performance Advantages of PIR Air Duct Board

01.

Excellent sound-absorption performance:

The core material of the PIR air duct is PIR foam plastic, and the surface of the air duct is embovered anti-rust aluminum foil. The average noise reduction can reach 3dB/m, and the noise at the air outlet is less than or equal to 47dB. It can eliminate the machine noise and aerodynamic noise of the air conditioning system without the need to install additional silencers and silencing elbows.

02.

Good thermal insulation and long service life:

The PIR air duct is formed by one-time high-pressure molding of PIR foam plastic, with a thermal conductivity of 0.018W/mK. The insulation and heat insulation effect is more than 2.5 times that of the traditional galvanized iron sheet plus glass wool or rubber plastic insulation air duct. Moreover, it has no air leakage or cold bridge phenomenon, and its service life can reach over 22 years, while the general service life of traditional galvanized iron sheet air ducts is 5 to 8 years.

product key technologies of PIR Air Duct Board

01.

Energy-saving and environmentally friendly:

Due to its good heat preservation effect, it can reduce Energy loss during the operation of the air conditioning system and lower electricity consumption. Taking the air conditioning supply system with 10,000 square meters of air ducts as an example, compared with traditional air ducts, PIR air ducts can save an annual electricity cost equivalent to 210,000 to 370,000 yuan. In addition, its materials are environmentally friendly and do not contain harmful substances such as formaldehyde.

02.

Good hygiene and anti-corrosion:

The inner surface of the air duct is made of materials such as aluminum foil, which is smooth and not prone to dust accumulation. It can ensure good indoor air quality and is suitable for places with high hygiene requirements, such as food processing and hospitals. Meanwhile, it has corrosion resistance and can be used in various environments without maintenance.
