Public places represented by airports, stations, and subways serve mobile crowds of different genders, ages, occupations, ethnic groups or nationalities, and different health conditions; the drinking water equipment in public places, as supporting facilities for urban public services, not only needs to avoid the hidden health and safety hazards brought about by the mobile population, but also needs to reflect the style and appearance of the city with high-quality services. AICKSN pays attention to the drinking water experience of passengers and ensures the safety and timely supply of drinking water for incoming and outgoing passengers.
