Gas Detection in Carparks

Due to exhaust fumes from cars and trucks, most carparks are fitted with a ventilation system extracting the fumes from the carpark. The ventilation system usually consists of air supply and exhaust fans.

In order to reduce the electricity cost, gas detectors are installed for controlling the fans. Depending on the system installed, the ventilation system can be either switched on or off or the fans can be accelerated when the concentration of exhaust fumes increase.

Carpark gas detection comprises out off Carbon Monoxide (CO) detection and NOx detection. Most carparks are fitted with CO detection only, large carparks which diesel trucks are fitted with both CO and NOx detectors. Not all carparks would be fitted with a ventilation system. In case there is enough natural ventilation, ventilation systems are not required. Gas detection in carparks falls under Australian standard AS1668.2.

In case you would like to fit an existing carpark with a detection system, Noventis can assist with the draft and design work.
