CTA Booth Was Interested by Media in Shenzhen Exhibition

14th Oct 2013


    On China Shenzhen International Logistics and Transportation Fair, CTA booth on the exhibition was very interested by medias. This is the first the Air Purification System was introduced formally on exhibition to people in China. CTA introduced its system, features, cases by posters and videos, which attracted many visitors.

Local medias like Guangzhou Evening, South TV, Shenzhen Radio interviewed CTA sales people and asked for detail information about the system. Like other big cities in China, Shenzhen is crowded and has plan to build more tunnels under city. But the exit of tunnel, with heavy polluted air, is always against by residential people nearby. Air Purification System can get the polluted air cleaned and make it even better than which of the surrounding area.


    So that's not surprised that a photo on the booth raised a lot of visitors interest, which is about an air exit from tunnel at the ground level. It's so impressed for the high technology behind and its significance to solve the practical problems nowadays.

    CTA will continue to promote tunnel air purification system around the world, to protect more people's health.
