PU PID Duct Panel For Central Air Conditioning System

PU PID (Pre-Insulated Duct) Panel is a high-performance integrated solution tailored for central air conditioning systems, combining insulation, air distribution, and protection in one compact structure. It's widely favored for modern commercial and residential HVAC projects due to its balanced functionality and efficiency.

Core Structure & Key Specifications

Structure: Sandwich design with a closed-cell polyurethane (PU) foam core (thickness: 10–30mm) and aluminum foil (0.05–0.08mm) bonded to both sides. The foil enhances airtightness, corrosion resistance, and surface durability.

Key Metrics: Thermal conductivity of 0.020 W/m·K, foam density of 50 kg/m³, water absorption ≤0.1%, and working temperature range of -60℃ to +80℃ (continuous operation ≤70℃). It meets airtightness standards with leakage <2% and fire ratings like Class B (EN 13501-1) or Class 0 (BS 476).

Internal Use:

Panel Structure: Silver Alu. / PU Foam / Silver Alu.

Foam Density: 50kg/m3

Panel Dimension: 3950/2950/2900*1200mm*20mm

Alu. Foil: Embossed 60 Micron

 

 

Superior Energy Efficiency: The low thermal conductivity of PU foam minimizes heat loss/gain, cutting central air conditioning energy consumption by 20–30% and lowering long-term utility costs.

 

Easy & Fast Installation: Lightweight (70% lighter than galvanized ducts) and pre-fabricated, it supports one-step installation without secondary insulation. It's easy to cut and assemble, slashing labor time by 40–60%.

 

Moisture, Corrosion & Hygiene: Closed-cell PU core blocks moisture entirely, while aluminum foil resists rust and pollutants. The smooth foil surface prevents dust buildup and mold, suiting hospitals, food plants, or clean rooms.

 

Durable & Quiet: High compressive (≥0.2MPa) and bending (≥2MPa) strength ensures structural stability, with a 20+ year lifespan. The PU foam core also absorbs airflow noise, reducing system operation sound.
