NocoStop® CO, NO and NO₂ – Air Quality Tunnel

NocoStop®
Single Gas CO, NO or NO₂

Gas Analyser for Parkings and Tunnels

Available for insitu or extractive measurement, the Nocostop™ enables accurate and reliable single gas monitoring for tunnel, roadside and parking applications. The Nocostop™ gas analyser is designed to measure continuously the concentration of carbon monoxide (CO) or nitrogen monoxide (NO) or nitrogen dioxide (NO2) accumulated in traffic areas. Online measurement is performed by high precision gas proprietary (CO, NO or NO2) electrochemical cells while the measured concentration is reported using the 4-20 mA output or available on local LCD display.

Continuous monitoring

The Nocostop™ gas analyser has been designed to measure continuously the concentrations of CO, NO and NO₂ in tunnels, parking, and roadside applications. With fast response time, extremely low detection limit the Nocostop™ ensures accurate and real time air quality control for the safety of tunnels and car parks users.

Ease of operation

The Nocostop™ full remote access capabilities with RC3 control unit minimises the need for sensor attendance and eases considerably maintenance tasks and diagnosis operations. Locally, sensor information can be collected using the analogue outputs, by direct connection or using the optional LCD screen.

Increased resistance

With its stainless steel unit (316L), the Nocostop™ Gas Analyser is highly resistant, making it the perfect monitoring instrument in extreme environments. Moreover, the Nocostop™ light weight enclosure features an integrated filter and a splash guard system to protect the measuring cell from fog and water spray.

Flexible Monitoring Solution

Pillard Nocostop™ is adapted to all tunnel and parking applications:

- - Single sensor solution
  - Insitu and extractive version
  - CO, NO or NO2
  - Wall mount light weight SS316L enclosure

Road and Train Tunnels

Air Quality Monitoring (AQM)

Tunnel ventilation system design will be best practice and operate within stringent air quality standards to protect the health of communities and drivers using the tunnels.

Road tunnels can help reduce air pollution by moving traffic off roads where people live and work, putting vehicles underground. In a tunnel, vehicle emissions can be controlled and dispersed more effectively and are monitored to ensure standards are met. With thousands of tunnels in the world, there are well-established and effective ways to design tunnels and ventilation systems so that there are no negative effects on local or regional air quality.

Tunnel ventilation system

Tunnel ventilation Systems rely on accurate Air Quality Tunnel Sensors installed to:

meet Australian States’ stringent air quality requirements – which are among the highest standards in the world
ensure high air quality inside the tunnel
manage emissions from current and future traffic volumes.

Underground Parkings

Air Quality Monitoring (AQM)

Parkings ventilation system design will be best practice and operate within stringent air quality standards to protect the health of communities and drivers using the underground car parks.

Pollution and noise in urban areas are an affront to the quality of life and health of citizens. That is why, air quality and well-being in urban areas are now regarded as rallying themes and represent a major public health issue for local authorities. Therefore, a number of different parameters can be measured such as noise, photo-chemical pollution NO2 (Nitrogen Dioxyde) or even fine particles. In addition, pollutants are measured on a regular basis at the level of ears and respiratory tracts.

The Pillard Air Quality Sensors for Tunnels and Parkings enable fast and accurate monitoring of the air quality and traffic emissions in underground parking facility (UPF) using carbon monoxide (CO), Nitrogen Dioxide (NO2) and Opacity as Air quality indicators. For this purpose, concentrations of pollutants are measured simultaneously and continuously and respective concentrations transmitted realtime to the BMS (Building Management System) and UPF control room.

Furthermore, vehicular emission factors (EFs) are controlled and the ventilation rates required to maintain pollutant concentrations within acceptable standards.
