Transport for London (TfL) has named Proventia Emission Control in a framework agreement as a supplier to the NOx Abatement Framework Agreement, ahead of the introduction of the ultra-low emission zone (ULEZ) in London.
The agreement means that Proventia is approved to supply, install and maintain selective catalytic reduction (SCR) retrofit systems for upgrading Euro 4 and 5 buses up to the Euro 6 emission standard for the London ULEZ.
The NOx Abatement project applies to around 5,000 diesel buses.
Proventia’s NOxBuster City system is tested and approved according to the TfL’s Millbrook London Transport Bus (MLTB) test cycle that represents Central London driving conditions.
Jari Lotvonen, president and CEO of Proventia, said: “We are very proud that TfL has selected state-of-the-art emission control technology from Finland."
NOxBuster City system is specifically designed for stop-and-go city traffic where exhaust temperatures usually remain low.
The system uses standard commercial AdBlue for reducing NOx. The installation does not require any major changes to the bus structure.
Through the new £86.1 million programme, TfL will retrofit around 5,000 buses with a new exhaust system that will significantly cut their emissions.
This will mean that by September 2020, the entire bus fleet will be at least Euro 6 standard.
Proventia will supply technology and components and Proventia’s long-term UK partner, Excalibre, will provide the installation and servicing of the systems.
