Road Tunnel Ventilation Systems

In order to ensure safe use of the tunnels, systems must be installed to provide daily and emergency (fire) ventilation to meet the international standards. These ventilation systems are used to remove the toxic exhaust gases of vehicles using the tunnel in daily ventilation, while in the event of an emergency, to provide the evacuation of smoke and hot air due to fire. Thanks to this system, in case of fire, people inside the tunnel escape to emergency escape tubes and outside of the tunnel while people are affected from the poisonous gas at minimum level, the vision distances are protected and panic is not ensured.
