Proventia Emission Control announced for London buses Euro 6 upgrade

It has been revealed that the external body that won the tender was Proventia Emission Control from Finland, 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.

In November 2016, Transport for London (TfL) permitted a tender for external support to provide NOx Abatement services to retrofit around 5,800 diesel buses to Euro 6 emission standard. This required the external body to supply, install and maintain their Selective Catalytic Reduction (SCR) retrofit systems.

The agreement between TfL and Proventia is to supply, install and maintain selective catalytic reduction retrofit systems for upgrading Euro 4 and 5 buses up to the most recent Euro 6 emission standard.

Proventia’s NOx Buster City system is specifically designed for stop-and-go city traffic and has been tested and approved according to the TfL’s Millbrook London Transport Bus (MLTB) test cycle which represents Central London driving conditions where exhaust temperatures usually remain low.

By September 2020, the entire diesel bus fleet in London will be at least Euro 6 standard through this new programme which will cost between £78-86million.

Proventia will supply the technology and components but Proventia’s long-term UK partner, Excalibre will provide the installation and servicing of these systems.
