In the context of the current pandemic, Electroalfa has developed an integrated solution to prevent and limit the spread of viruses in public spaces, workplaces, buildings, and other entrances with heavy human trafficking. The tunnel creates an obligatory passage and is equipped with, spaying nozzles that saturate the environment but preventing dispersions. The nebulization system is connected to a control system capable of automatically spray the sanitizing products. Access to the tunnel is regulated by motion detection, it stops spraying when people walk out. The tunnel is equipped with a disinfection mat on the ﬂoor and it is possible to sanitize also the feet or surfaces in contact with the ground.
