By-Pass Installation

By-Pass Installation
In a bypass installation, polluted air is forced through a crescent-shaped side tunnel containing precipitation equipment. The system used in Norway's Granfoss, Ekeberg, Lardalstunnel and Chinbu Tunnel in South Korea - all installed and serviced by CTA International AS. More facts on Lardalstunnel, "The World Longest Rock Tunnel," can be found on the site of The Norwegian Road Authority.


Advantages of CTA's bypass system compared to other bypass systems:

Higher system efficiency

Total installation costs are lower

Lower operating costs

Improved airflow characteristics

Lower excavations costs: requires ca. 30% less rock
volume to be removed
