Public transportation is an important tool for people to travel. As a public space with a large flow of people, it is a place where viruses and bacteria are easily transmitted. Therefore, it is a key disinfection and sterilization place in each city. The difficulty of sterilizing the publictransportation lies in large space, poor air circulation and concentrated personnel density. BeyondSmartor UVC LED sterilizer uses the third-generation ultraviolet chip high-power module to irradiate, which is not limited by space, and can completely eliminate viruses and bacteria at 360 degrees, without harmful gas residues, and will not affect human breathing in a confined space. In addition, the sterilizer has no corrosive effect on the facilities, and can be moved and sterilized independently, greatly reducing manpower input.
