Big project was completed at Zhonghe Junior High School Preschool this week. Mr. Feng,the chairman,said it was extremely exhausting to walk for meters and sterilize all the 10 classrooms by carrying the uvc light so to solve this problem, we spent 2 days installing a uvc light lamp set for each classroom and a central control box.What a huge project! Instead of carrying the sterilizer, just pushing the bottom and all the classrooms could be disinfected by only one bottom. It was a great relief to provide a better environment for children and let teachers work more easily.
