PROVENTIA UPGRADES LONDON BUSES TO ULEZ EURO 6 LEVEL

Transport for London (TfL) has named the Fnnish company Proventia Emission Control in a framework agreement as a supplier to the NOx Abatement Framework Agreement, ahead of the introduction of the world’s first 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 IV and V buses up to Euro VI emission standard for the ULEZ.

The NOx Abatement project applies to around 5,000 diesel buses. 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. The system uses standard commercial AdBlue for reducing NOx. The installation does not require any major changes to the bus structure. The Proventia retrofit system also includes an online emissions monitoring system, Procare Drive, that provides 24/7 updates of the level of NOx emissions from the buses, and full remote monitoring of the system operation. The operation of Proventia NOxBuster City system is a proven and effective solution for Euro VI retrofits, checked by several independent test organizations both in laboratories and PEMS tests. With the same technology Proventia has upgraded Euro IV, V, EEV and hybrid buses up to Euro VI emissions level for major bus operators in Finland, Sweden and Norway.

Retrofitting buses to Euro VI standard is the quickest and the most cost-effective way to cut NOx and other harmful emissions from existing bus fleets, says the company. Through the new £86.1m 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 VI standard.

Proventia will supply technology and components and Proventia’s long-term UK partner, Excalibre, will provide the installation and servicing of the systems. Proventia and Excalibre have previously successfully cooperated on the retrofit of over 350 Euro III ADL Tridents and Darts to the Euro V standard.
