AHU
Delivering clean, comfortable air
An air handling unit (AHU) conditions, filters and circulates fresh air throughout a building — regulating temperature, humidity and indoor air quality for large or sensitive spaces. AHUs are the right choice wherever air quality itself matters as much as temperature: hospitals and pharmaceutical facilities need precise filtration and pressure control, while hotels and office towers need consistent comfort across large, varied floor plans. Sizing depends on required airflow (CFM), fresh-air ratio, and filtration grade for the specific use case. We consult on, design, supply and install AHUs matched to the ventilation and air-quality requirements of each project, from hospitals and pharmaceutical facilities to hotels and office towers.

Choosing and quoting: AHU
An air handling unit (AHU) filters, cools or heats and distributes air through a building, and is used in large halls such as cinemas, amphitheaters, hospitals and factories. Air flow, fresh-air share and static pressure are the three main selection numbers.
For an AHU quotation, state the room volume, number of people, required fresh air, filter type and install location (indoor or rooftop). For cinema and conference halls, see our guide to HVAC for halls.

Frequently asked questions
What does an air handling unit (AHU) do?
An AHU filters, cools or heats fresh and return air and distributes it through ducts. It is used in large buildings, halls, hospitals and factories to supply clean, controlled air.
What do you need to select an AHU?
Airflow, required static pressure, coil type (chilled water, hot water or direct expansion), filtration level, installation location (indoor or roof) and allowed dimensions. Drawings or building details are the best starting point.
Is an AHU suitable for a cinema or conference hall?
Yes. Crowded halls need plenty of fresh air and quiet air distribution, and an AHU with suitable ductwork provides this. Exact size and type depend on the hall capacity.
