Treated Fresh Air Unit (TFA) The horizontal floor mounted units are ideal for handling high air quantities. The modular design sections offer both sturdy construction and flexible combination of components such as coils and filters to suit specific applications. Hence they are widely used for industrial, clean rooms and large commercial airconditioning. As all major components are aligned to the base tray, it is maintenance and service friendly. Durability and Reliability The rigid framework comprises of an assembly of externally rounded, anodised, extruded aluminium profiles which are anti-corrosive. Glass filled nylon corner joints avoid water condensation at the corner. The 25 mm thick panels are pressure injected with polyurethane foam, using CFC free R- 141b blowing agent. High and uniform PUF density of 38 +- 2 kg/m3 provides better thermal conductivity and sound attenuation properties. Good Looks
No gaps and level difference at panel joints. Fixing screws are avoided in assembling panels. High Indoor Air Quality
Double skin panel construction allows easy inspection, cleaning and maintenance of the smooth inner surface, reducing the risk of dirt and bacteria accumulation. There is no corrosion of internal insulation material to contaminate the air stream. Improved panel frame arrangement by overlapping wedge and special gasket reduces air leaks into the casing significantly. This maintains the Indoor Air Quality (IAQ) and also provides better thermal and acoustic performance.
Low Sound Usage of double skin casing, imported AMCA certified fans, anti- vibration spring isolators, which isolators the fan from the main structure minimizes vibration resulting in low noise operation. High Quality Filters The filter media is of the synthetic non-woven types, supported with aluminium mesh. The filter efficiency is 90%, down to 10 microns. The filter sizes are standardized to the internationally recognized standard of 4 sizes. Energy Efficient The units free flow coils. The fins of these coils have a mild ripple and die formed channels to improve heat transfer efficiency and hence are energy efficient.
