Products Description
Insulated duct (thermal-insulated air duct) is a pipeline solution for heating, ventilation, and air conditioning (HVAC) systems, primarily composed of inner and outer double-layer metal/non-metal pipe walls and an intermediate thermal insulation layer. Its typical structure includes:
Thermal Insulation Layer: Polyurethane foam (thickness: 10-80mm)
Outer Layer: Galvanized steel sheet/aluminum alloy (thickness: 0.5-1.5mm)
The Advantages of Insulated Duct
Thermal Efficiency Optimization
With a thermal conductivity as low as 0.022-0.035 W/(m·K), it reduces energy loss by over 30%.
Anti-Condensation Design
The surface temperature always stays above the dew point temperature, making it suitable for environments with humidity >60%.
Acoustic Performance
The Noise Reduction Coefficient (NRC) can reach 0.8, effectively reducing noise from the duct system.
Fire Rating
Complies with ASTM E84 Class A/EN 13501-1 standards, with smoke density <50.
Installation and Maintenance
Recommended Connection System: Flange connection is advised for secure assembly.
Leak Test: Perform airtightness detection every 5 years to ensure system efficiency.
Cleaning Guidelines: Use dedicated negative-pressure vacuum equipment for cleaning to prevent damage to the thermal insulation layer structure.
