Descriptions
Embossed one side, smooth on the other side with 50+/- 2Kg/m3, 20mm thickness, with 80 micron aluminium foil and 150 micron smooth aluminium sheet coupled with layers of corrosion resistant, anti mold & anti bacteria paint. (For clean room, Operation Theatre, semi-con, F&B factory use and etc).Product Characteristic
TDM Pre-insulated aluminium duct is developed as an alternative to the conventional ducting system. It is a sandwiched panel made of PIR (POLYISOCYANURATE) foam covered in smooth or embossed 80 micron aluminium foil (anti-mould & anti bacterial coated) . Nice in aesthetic, doesn't rust, non fibrous, zero permeability, anti mold and anti bacteria, contain no HCFC, lower air leakage, doesn't absorb moisture and fast installation speed.
All pre-fabrication work can be done before sending to the site, reduce wastages and much lesser workers needed at site . It is silent in operation at site.
TDM duct is very light weight, 6 times lighter than G.I. duct with insulation . This significantly reduced building load, roofing load and ceiling load. Also it uses less hanger , less labour and faster installation time. Suitable for commercial office buidings,factories and malls.
- Maximum pressure in duct is up to 2,000 Pascal or 8” WG.
- Can be used for AHU connection due to its high rigidity. Can be easily dismentle and re-assemble back for cleaning, maintenance or modification purposes.
- Thermal conductivity is 0.022 W/m°C with no mechanical joins on the longitudinal duct section. Therefore is thermally better and very minimal leakage compare to conventional duct system.
- Nice aesthetic for expose type ducting and can be covered with paint to suit architectural purposes.
