PRODUCTS-AIR QUALITY CONTROL

In enclosed spaces such as tunnels or underground parking the concentrated air pollutants from vehicle exhaust pipes, are particularly harmful to humans. These pollutants, such as nitric oxide (NO) and carbon (CO) is invisible, odorless and can even cause death by asphyxiation.

Special safety standards impose that in all enclosed spaces from where vehicles pass through there should be a ventilation system which shall be controlled by special organs measuring these pollutants. These instruments directly or through a more intelligent central automation (PLCs) activate ventilation fans for air renewal.
