The Double Skin Modular Air Handling Unit is designed based on modular paneling concept to fulfill the indoor air quality requirement. The air flow of DM AHU is within range of 330 to 20, 000 lps (700 to 42379CFM) and up to a total static pressure of 1991 pa (8 W.G). For special design, the air flow can be reached25, 000 lps (52974 CFM).The AHU is constructed of high strength extruded Aluminium to form rigid frame. Besides, it is with thermal barrier feature which using three leg-fiber plastic corner pieces, 25 or 50 mm Polyurethane (PU)insulation panel and all frames are insulated with 3.0 mm PE foam to minimize energy heat loss and prevent condensation occurring. The external clip method to hold the double skin PU insulation panel is easily accessible for maintenance while being air tight. The new thermal- break profile can perform better than the original profile in terms of providing better insulation and energy saving.There is selection software programme available: DM AHU, to optimize the best arrangement and performance for either chilled water system or DX system. Standard components can be selected and be placed according to customer requirement. Once the unit is defined, optional item and accessories are identified. The programme gives immediate feedback if there is no suitable choice for the units. The programme provides us with fan curves data, coil performance data, dimension, and shipment weight. McQuay can produce high quality, flexibility air handling unit which can provide excellent thermal efficiencies and to be airtight. Besides, air handling unit produced is with flexibility features to meet the indoor air quality, operating efficiency, sound level and installation requirement for todays extensive

• Application :Cooling, Heating, Dehumidification,
• Humidification in shopping malls, offices, restaurants, health care, multiplex, clean rooms and all type of industrial application
• Wide capacity range :2040 CMH to 59500 CMH
• Comfort to Industrial :pressure range from 250 Pa to 1500 Pa
• Product Range for all Application :

These units are suitable for large air quantity. The modular design allow flexible combination of component to suit specific application. hese AHUs are ideal for large commercial / office / industrial / hospitality / healthcare application.

These units are preferred when floor space is at a premium. Vertical units are units designed with filter coil & fan all arranged in a vertical frame. The advantage of these units are they occupy less floor space. Floor Plates where low ceiling height is a constraint multiple vertical units can be used to advantage. Where no AHU rooms are provided exposed units with supply air plenum can be used.

These units are suspended from ceiling slab above false ceiling and thus require no floor space & AHU rooms. These units are
