Specific setups enable event-specific support with adjusted air conditioning, air flow rate and air routing. These govern the room temperature, relative humidity, air volume and air distribution throughout the hall. Together with lighting, pyrotechnics and fog machines, the climatic scenarios contribute significantly to the drama of a wide range of events, as well as to the feel-good factor amongst visitors. A prerequisite for the dynamic response of the ventilation systems are air handling units that can respond immediately to the setups and ensure maximum flexibility and availability – that is to say WOLF air handling units.
