Modular Air Handling Unit


MAHUs are modular so that they have the flexibility to add components as required. The 3rd generation Midea MAHU adapts unitary structure design, more outstanding cold – bridge free performance, lower air leakage and more elegant appearance. It realizes a variety of functions: cooling, heating, humidification, dehumidification, air purification, noise elimination, and so on. The air flow rate is available from 3,000m3/h to 200,000m3/h. Total pressure (TP) exceeds 2000Pa to adapt to different kinds of applications, such as office buildings, shopping malls, exhibition halls, airports, railway stations, hotels, chemical fibres, electronics industries, textile mills, tobaccos, hospitals, printers, automobile factories and any other central air-conditioning systems.

Product Description


Reliable quality

For the 3rd generation of Midea MAHUs, reinforced frame is built in the section connection gap to enhance the structure for large air flow volume and high air pressure. The MAHUs’ construction provides unequaled thermal efficiencies and low leak rates. In addition, the MAHUs offers tremendous flexibility in sizing, component options, and unit arrangements to meet the indoor air quality, operating efficiency, sound and installation requirements for today’s extensive commercial and custom markets. Also, Midea combines comprehensive performance certifications with thorough laboratory testing and manufacturing methods. These assure that each MAHU operates predictably and reliably throughout the life of the unit.

Modular design

The MAHUs adopt modulus design. Usually including mixing section, primary efficiency filter section, medium efficiency filter section, high efficiency filter section, cooling coil section, heating section, humidifier section, sound attenuator section, service section, heat recovery section, fan section and so on. Function sections can be combined freely. Different function sections can be selected according to the specific applications. The MAHUs can be shipped in divided sections. Each section is wholly completed at manufacturer’s work place, and only connection of sections can be done at site. Oversized units cannot be fitted in normal container shipment or cannot be delivered through access at site can be considered shipment in complete knock down form, but reassembling works must be done by engineers of the manufacturer.

Cold bridge free structure

Unitary structure design and module panel design. Panels are double-skin with injection of high density polyurethane. The outer skin is anti-corrosion color-coated steel sheet, the inner skin is galvanized steel sheet, the density of polyurethane is more than 50kg/m³, and the thermal conductivity is 0.0224W/m²·K. The unit cabinet is constructed by panels with male and female aluminum alloy cards and sealing strip. The air leakage rate is less than 0.29%. Units will not sweat when exterior room temperature is 27 °C, relative humidity is 90%.

State-of-the-art design

The MAHUs adopt unitary structure design and the insert fastening bolts are covered by haps which are in accordance with the color of the outer skin, and clear, smooth appearance make the outlook attractive.


The Midea MAHUs are designed to provide easy access to interior components for routine maintenance and service. The easy-to-move panels and access doors of the units provide complete access to the unit interior and components.

Wide usage

Midea MAHUs can be widely used in chemical fibres, electronics industries, textile mills, tobaccos, hospitals, printers, automobile factories and any other central air-conditioning systems, especially these have special requirements of environment space.
