Withair® offers a full range of air handling equipment and systems to meet your performance requirements. From 1500 cfm to the highly flexible 60,000cfm with numerous custom options,multi-static pressure choice,compact structure,humidifier, perfect cooling and heating performance, optional with air valve,water baffle and etc, tt can be applied for shopping mall,hotel,office building ,show fair and other comfortable areas. to a completely custom, energy-efficient, environmentally responsible system, Withair® has the optimal solution for commercial, industrial, institutional or process applications. All Withair® AHUs are designed to be energy-efficient, with several energy recovery options available to minimize energy consumption. we also offers several dehumidification options.
Withair® air handler, or air handling unit (AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.Withair® an air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.Withair® Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork
Withair® air handler is normally constructed around a framing system with metal infill panels as required to suit the configuration of the components. In its simplest form the frame may be made from metal channels or sections, with single skin metal infill panels. The metalwork is normally galvanized for long term protection. For outdoor units some form of weatherproof lid and additional sealing around joints is provided.
Withair® small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; these simple terminal units are called blower coils or fan coil units. A larger air handler that conditions 100% outside air (fresh air), and no recirculated air, is known as a make up air unit (MAU) or fresh air handling unit (FAHU). Withair® air handler designed for outdoor use, typically on roofs, is known as a packaged unit (PU) or rooftop unit (RTU).
Withair® larger air handlers will be manufactured from a square section steel framing system with double skinned and insulated infill panels. Such constructions reduce heat loss or heat gain from the air handler, as well as providing acoustic attenuation. Larger air handlers may be several meters long and are manufactured in a sectional manner and therefore, for strength and rigidity, steel section base rails are provided under the unit.
Withair® air handling unit; air flow is from the right to left in this case. Some AHU components include: Supply duct, Fan compartment, Vibration isolator ('flex joint'), Heating and/or cooling coil, Filter compartment, Mixed (recirculated + outside) air duct, heat wheels, humidifiers, run around coils, heat exchangers and more.
Withair® AHU is used to control the following parameters of the space.
