To verify and to be able to develop
higher efficiency on our EP-S cells we have contacted experts on measuring efficiency, both by weight and particle count.

These tests have been carried out by experts on the high-voltage area, and give us facts on our progess to maintain our position as a leading global EPS supplier.

For more facts about the efficiency tests please contact us.

Presentation on the 6th China Tunnel Summit


   On Mar 29th, 2012, CTA delivered a speech on the 6th China Tunnel Summit. The summit topics comprise: construction experience of super long tunnel, innovative construction technology and case analysis, low carbon energy conservation and sustainable project management solution etc.

    CTA introduced its advanced technology on air treatment for tunnels. The CTA system can remove particles, NOx, CH etc, which attract customers and designers insterests very much. In China, many tunnels are with the problems of high pollution, low visibility.
