Since the beginning of September 2021, our CityTree has been tested in an industrial environment for the first time. In the production hall of the manufacturer Refratechnik Ceramics, it stood until recently near the tunnel kiln, where air pollution was strongly felt. Thanks to the special air quality sensor technology, we can also measure and display the special benefits and performance of the CityTree.
The air in the hall is completely recirculated and filtered every day
After an initial constant air circulation, the daily schedule was adapted to work days and weekends, with more air being filtered during working hours than on days off. Every day, an air volume of over 30,000 m³ can thus be purified. This means that the air in the hall with an area of 6,000 m² is completely circulated and filtered once a day.
