The wide range of AHUs manufactured in the production unit are with world class capabilities and special features like internal covings & thermal brake external frames. They are tailor made depending on the design, applications, availability of space and similar other parameters. The Air Handling Units can be broadly classified as : Single Skin Air Handling Units - for all Ventilation applications Double Skin Air Handling Units - for all Air-conditioning applications Single Skin Air Handling Units As the name suggests, has a single casing made of G.I. or of material as per requirement. Double Skin Air Handling Units As the name suggests, has an outer casing made of sandwiched panels with polyurethane foam acting as a thermal barrier for better insulation. Constructional Features (External Body & Framework) The rigid framework of the unit comprises an assembly of externally chamfered extruded anodized aluminium profiles and nylon glass fibre corner joints. This when incorporated with polyurethane foam, 25 mm / 43 mm, thick, pressure injected sandwiched panels, makes the entire unit anti-corrosive and sweat free. Also, the imported self drilling and self tapping galvanized sheet metal screws adds to the aesthetic beauty of the framework.

Inner Body & Components of the Unit The highly smooth inner surfaces of the panels along with internal covings, reduces drastically the risk of dirt and bacteria accumulation. There is no erosion of internal insulation material or any welding of the joints to provide an air steam with zero contamination. Drain Pan (for air-conditiong applications) The condensate drain pan is fabricated from 0.8 mm / 1 mm thick G.I. / SS304 depending on the application. This wider drain pan with differential slope assures quick and complete water drainage, thus avoiding migration of moisture, which is the major cause of microbiological growth. Filters The unit is provided with 10 / 20 micron, easily washable factory manufactured prefilters. These filters are generally confirming to EU-3 of EN-779 specifications. Also, depending on the requirement, microvee and HEPA filters can also be provided in the unit. Blower Usage of imported Kruger/Nicotra make (AMCA certified) blowers along with anti-vibration spring isolators and rubber mountings isolates the fan from the main structure, thus minimizing vibrations and hence low operating noise. The blowers are balanced after complete assembly to G2.5 level. Fans with the balance grade of G1.0 can be upon request. Cooling Coil The staggered tubes, corrugated plate fins and die formed channels form mild ripples of the flowing air, thus providing excellent heat transfer capability with low air side pressure drop. Mechanical expansion of copper tubes with aluminium fins assures tight bonding to enhance the heat transfer. Performance Standards Generally in accordance to : Fan : AMCA 210 Coils : ARI 410 Motors : S-325 Filters : BS-6540 / ASHRAE 52-76   Other filter sections can also be added depending on the requirement.Specification are subject to change without prior notice.
