CPS Car park gas detection controller (Car Park System)
The CPS car park gas detection system (Car Park System) has been specially developed for measurement and control of pollutants in parking lots and tunnels. This continuous monitoring system significantly reduces operating costs by optimizing ventilation systems’ efficiency.
Available in a 19’’ wall or rack version, the CPS gas controller panel and its various alarm modules can manage up to 256 gas transmitters distributed over 8 lines. Several fan run orders are available such as low or high speed, timed run, forced run, night mode, etc. Detailed description
Parking gas detection
The presence of gas detection systems in parking lots is a necessity for user’s safety. Car parks are confined spaces and exhaust gases released by vehicles’ combustion engines can be dangerous for health, hence the need to set up a parking gas detection system.
The main harmful gases present in car parks and tunnels are carbon monoxide (CO) and nitrogen oxides (NOx). Other gases are also present, in lower concentrations such as LPG and recently hydrogen (H2) emitted when charging electric vehicles.
Real energy savings with the CPS controller
In order to minimize risks associated to combustion gases presence, most car parks are equipped with air extractors. These devices, although effective, are very expensive energy-wise because ventilation systems operate at fixed times or randomly unrelated to the present toxic gases concentrations…
The technology used by the CPS parking gas detection controller allows continuous air monitoring. The direct consequence is a significant and immediate operating costs reduction in addition to the safety aspect of air quality control. We can thus have an appropriate management of ventilation systems and other controls which will be optimally controlled based on exact gas concentrations.
