Detailed Description

It is developed specially for the air distribution in HVAC applications. Polyurethane foam panel with 52 ± 2 Kg/m3 density, 20 mm thickness, coated with 80-micron thick aluminium foil on both sides. The aluminium foil is embossed on both sides and coupled with a layer of corrosion-resistant polyester paint. This panel is especially suited for use in air-conditioning and heating system installations. We got the certificate for our PU Panel in Australia; it is approved by third party in Australia as per AS/NZS 1530.3-1999.the methods for fire tests on building materials, components and structures - Simultaneous determination of ignitability, flame propagation, heat release and smoke release. We are manufacturing based on it. The general standard as below: Panel dimension: 4000 x1200 mm Panel thickness: 20 mm Foam density: 52±2 kg/m3 Aluminium thickness: 80/80 micron Thermal conductivity: 0.021 W/m.C Compressive strength: 200 N/mm2 Flame retardant: B1 Friction coefficient: 0.0135 Panel Weight: 1.46 kg/m2 Working temperature: -60~+80C Humidity: 0~100% Pressure in duct max: 2,000 Pa Air flow max: 12m/s Aluminium foil embos./embos Advantages Thermal insulation: constant and continuous in all duct sections. Special closed-cell insulation guarantees low thermal conductivity and limit the risk of condensation. Friction loss: the low number of flanges and limited surface roughness keep linear friction losses at very low levels. Airtight seal: air tightness of TD pre-insulated ducts is eight times more than conventional ducts. Energy saving: perfect thermal insulation, low friction loss and optimum airtight seal allow for maximum exploitation of air handling unit capacity, increasing efficiency and reducing operating costs. Hygiene and air quality: the use of aluminium for the internal surfaces of the ducts ensures hygiene and cleanliness. The problem of ageing of the insulation and consequent release of particles is non-existent. The use of aluminium with glue and anti bacterial coating which give an additional protection and harmless; no moulds, viruses and bacteria grow on its surface. Safety: TD pre-insulated ducts have a low participation in fire, do not drop and smokes have a reduced opacity and toxicity. Our product is in conformity with the requirements of the most restrictive international regulations. Silent operations: the sandwich structure (aluminium - insulating material - aluminium) guarantees a good acoustic behavior. Vibration and reverberation are stopped by the insulating material, contributing to a higher comfort in the environment where TD pre-insulated duct is installed. Light weight: the very light weight allows a reduction of weight on the structures, supporting points, workmanship costs and materials necessary for the installation. Construction easiness: possibility of manufacturing ducts in the work shop or directly at job site with considerable advantages on transport costs. Maintenance and modification easiness: TD pre-insulated ducts can be maintained and modified in any section on site. Duration: the outer aluminium coating coupled with the insulating material provides sturdiness, rigidity and good resistance to corrosion, erosion and deformation even in special applications.
