Road Tunnel Ventilation

In road tunnels ventilation rates are needed to dilute the pollutant emissions from vehicles - like Carbon Monoxide (CO), Nitrogen Oxides (NOx) and soot (particles matter) - in order to keep acceptable air quality for the users.

Just as important is controlling the effects of a fire in tunnels. The ventilation system needs to be designed and sized to provide sufficient velocity and direction for controlling the spread of smoke and heat in the event of fire.

The ventilation systems can be configured depending on different key elements such as: length, traffic direction, gradient, flow rates, fire size and scenario etc.

Systemair provides technical expertise for the design of the ventilation systems, supplies state of the art products and gives support for the installation, commissioning and operation of the delivered systems.
