Tunnel Monitoring Application Ventilation in tunnels shall provide for adequate breathing air for drivers and maintenance staff in tunnels as well as for sufficient visibility in the tunnel atmosphere which is contaminated with exhaust and dust. Also emission of pollutants to the environment shall be minimized and in case of fire it shall reduce the effect of heat and smoke. DURAG produces service reduced sensors and analysers, which precisely and reliably transmit the data of tunnel atmosphere to the ventilation control system. 2004/54/EC “tunnel” guideline as well as the national specifications...
