Over the last two decades, Metro Rail has transformed Urban public transport in India. Many cities have state-of-the-art trains running on overhead tracks and underground tunnels with world-class stations and support Infrastructure.
underground Tunnel
Each underground Tunnel is equipped with several shafts, which are used for intake and exhaust air and require intake and Exhaust Louvers at the Street Level.
CARYAIRE intake louver Model no IL-449 G series suits such kinds of applications. These louvers meet the Stringent Criteria of Metro Specifications.
air column
CARYAIRE OTE Damper suites for such applications are also tested and third-party certified for high temperatures
As the trains move across the tunnel network, they Push a massive air column in front of them and also create a negative pressure behind them.
This air movement is controlled through the OTE (overhead Trackway Exhaust) Dampers. CARYAIRE OTE Damper suites for such applications are also tested and third-party certified for high temperatures.
tunnel ventilation fans
To take care of air contamination due to train movement the train stations are equipped with tunnel ventilation fans. These Axial fans create sound, which needs sound attenuators.
CARYAIRE sound attenuators SP series are suitable for such applications and meet the requirements of metro specifications.
