Polyurethane (PU) Foam Pre-Insulated HVAC Ductwork Panel

Economic efficiency throughout the entire life cycle of UNT PU Air Conditioning Duct Panel

Adopting advanced third-generation modified MDI raw materials endows the PU air conditioning duct panel with exceptional durability and anti-aging properties, effectively extending the product's overall service life to more than 30 years under conventional operating environments. This lifespan is 2 to 3 times longer than that of conventional thermal insulation materials commonly used in the HVAC industry, which usually suffer from aging, deformation and performance attenuation after 10 to 15 years of service. Meanwhile, the product achieves a groundbreaking breakthrough in recyclability, overcoming the long-standing industry bottleneck of non-recyclability and low reuse rate of traditional insulation panels. Discarded and waste duct panels can be fully recycled after professional crushing, screening and secondary shaping processing, and the recycled finished products are still able to retain over 85% of the original physical and thermal insulation performance, realizing resource recycling and greatly reducing material waste.

Taking large-scale industrial plant HVAC system projects as a typical application scenario, this high-performance PU duct panel delivers remarkable economic benefits throughout the whole life cycle. Compared with traditional thermal insulation solutions that require frequent maintenance, replacement and secondary construction, the application of this upgraded duct panel can cut the comprehensive whole-life-cycle cost of industrial thermal insulation engineering by up to 28%. The cost savings cover multiple dimensions including material replacement cost, manual maintenance expense, system energy consumption loss and later operation and maintenance investment, bringing more stable and cost-effective operational guarantees for industrial building ventilation and air conditioning systems.

Core Performance of PU Air Conditioning Duct Panel

Cleanliness & Antibacterial Performance The interior self‑cleaning coating adopts bionic lotus‑leaf effect, which greatly inhibits the adhesion of dust and contaminants. Complemented by high‑efficiency antibacterial coating, it delivers an antibacterial rate above 99%. This addresses the long‑standing pain points of dust buildup and bacterial proliferation commonly seen in conventional air ducts.

Thermal Insulation & Energy‑Saving Capacity Boasting an ultra‑low thermal conductivity of 0.02 W/m·K, it outperforms traditional metal air ducts by a large margin in thermal insulation. It effectively mitigates heat loss and surface condensation for HVAC air‑conditioning systems.

Superior Durability It possesses outstanding corrosion resistance, low‑temperature tolerance and anti‑vibration capability. Maintaining good flexibility even at ‑40 °C, the duct can serve over 20 years under corrosive working conditions such as chemical plants and marine environments - 3‑4 times the service life of conventional air ducts.

Fast‑track Installation Its weight is merely one‑third of conventional sheet‑metal air ducts. Heavy lifting machinery is not required; manual handling and on‑site installation are feasible. Flexible cutting and splicing enable easy adaptation to complex ceiling structures and confined spaces, significantly shortening overall construction cycles.
