NOx emissions monitoring systems for Helsinki buses

Proventia has delivered NOxBUSTER® DPF + SCR exhaust aftertreatment systems and the PROCARE™ Drive emissions monitoring systems for 37 buses on a bus route in Helsinki where the annual threshold values set for nitrogen oxides (40 μg/m3) in the EU directive on ambient air quality have been exceeded over several years.

The installation of the aftertreatment and monitoring systems was connected to the objective of Helsinki Region Transport (HSL) to significantly reduce emissions from public transportation affecting the quality of air by 2025.

Proventia's NOxBUSTER® DPF + SCR system minimises emissions of particulates and NOx. PROCARE™ Drive emissions monitoring system allows HSL and the bus line operator to monitor the functionality of the EAT system and vehicle-specific NOx emissions in real-time.

PROCARE™ Drive emission tracking solution includes a data logging device installed in a vehicle and the web service. With the Proventia PROCARE™ Drive system vehicle emissions can be monitored and reported reliably.
