Products Description

PI Duct, namely Pre-Insulated Duct, is a key innovative product in the heating, ventilation and air conditioning (HVAC) system. Its structure usually adopts a sandwich design, with polyisocyanurate (PIR) foam or phenolic foam, etc. as the core insulation layer.

Take PIR foam as an example. It is sandwiched between two layers of aluminum foil. The aluminum foil not only enhances the stability of the overall structure but also further improves the heat insulation capacity. For instance, common specifications include 3950mm * 1200mm * 20mm. Such size designs are convenient for transportation and installation.

Performance advantage of PI Duct

01.

Excellent heat insulation performance:

The PI Duct made of PIR foam has a low thermal conductivity, generally ranging from 0.022 to 0.024W/m · K. This means that under the same conditions, the amount of heat transferred through the PI Duct is very small, which can effectively reduce the cold and heat loss of the air conditioning system, maximize the utilization of the capacity of the air handling unit, improve energy efficiency and reduce operating costs.

02.

High air tightness:

Combined with special connection and reinforcement accessories, the air tightness of the PI Duct system far exceeds that of traditional air ducts. For instance, its air tightness is more than eight times that of traditional air ducts, effectively preventing air leakage and ensuring the efficient operation of the HVAC system.

Application scenarios of PI Duct

01.

Commercial buildings:

shopping malls, hotels, office buildings and other places. PID Duct can meet the demand for efficient HVAC systems in large Spaces, ensuring a comfortable indoor temperature. At the same time, its aesthetic appeal also meets the decoration requirements of commercial buildings.

02.

Industrial field:

In industries such as food processing, electronics, pharmaceuticals, hospitals and medical centers, PID Duct provides ventilation solutions of high quality and high hygiene standards to ensure the stability of production and medical environments.
