In close collaboration with the engineering and production department of RAVO, ENS developed a customized solution in which proprietary ENS positive ionization technology was integrated into the RAVO 5i Series. This resulted in the first of its kind street sweeper utilizing fine dust elimination technology, the RAVO HYGiON. The ‘Berliner Stadsreinigung’ in the city of Berlin was the first to employ RAVO HYGiON street sweepers.
Given the limited amount of space available in the street sweeper, it was a real challenge to integrate the positive ionization technology. Nevertheless, it resulted in a great success: TÜV (‘Technischer Überwachungsverein’) has determined and certified that the HYGiON achieves a PM10 reduction of more than 80% and a PM2.5 reduction over 75%. This is a wonderful example of how a jointly developed innovation contributes to a healthier environment.
