Product Definition and Core Positioning of PID Pre-Insulated Duct
PID (Pre-Insulated air ducting) prefabricated insulated air ducts are factory-fabricated integrated ventilation ducts that integrate three major structures: the base material of the air duct, the insulation layer, and the protective layer. They do not require secondary insulation construction on site and are mainly used in HVAC systems, clean workshop ventilation, industrial waste heat recovery, and other scenarios.

Key Performance Advantages of PID Pre-Insulated Duct
Energy-saving and highly efficient:
The integrated insulation structure reduces cold/heat loss, lowering the system's operational energy consumption by 20% to 30%, in compliance with the national "Energy Efficiency Design Standard for Public Buildings".
Anti-corrosion and anti-condensation:
Dual protection of inner galvanized layer and outer protective film to prevent rusting on the inner wall of the air duct and condensation on the outer wall, reducing maintenance costs.
High air tightness:
Factory-prefabricated joints are few, with an air leakage rate of ≤0.5% (far lower than the 2% required by the national standard GB 50243), ensuring ventilation efficiency.
