Euro 6 retrofit launched by Proventia and Excalibre 21 September 2016

Finnish NOx reduction specialist Proventia Emission Control and UK exhaust systems firm Excalibre Technologies have today (21 September 2016) launched equipment claimed to make older trucks and buses compliant with ULEZ (Ultra Low Emission Zone) requirements.

Dubbed NOxBuster City, it has been designed to work with Euro 4-, 5- and EEV-engined heavy duty vehicles, bringing them up to full Euro 6 exhaust emissions standards.

Importantly, Proventia’s technology is also claimed to handle lower temperature, city operations that can be challenging even for some Euro 6 SCR (selective catalytic reduction) after-treatment systems.

Under the terms of their partnership deal, Proventia will supply the technology and components, while Excalibre handles sales, marketing, installation and servicing of the equipment throughout the UK.

According to an Excalibre spokesperson, the technology is already on trial on hybrid busses in London and is demonstrating that the Euro 6 exhaust emission standards can readily be met.

NOxBuster City is said to exceed TfL’s (Transport for London) retrofit specification on chassis dynamometer testing over the MLTB (Millbrook London Transport Bus) cycle.

The system is also already in use in Scandinavia and has been proven by independent organisations both over chassis dynamometer testing (WHVC test cycle) and in real world driving with PEMS (portable emissions monitoring system) equipment.

Excalibre says that each vehicle will also be fitted with the Procare Drive, a web-based clean air fleet management tool that monitors the vehicle’s exhaust after-treatment performance and provides for remote monitoring 24/7.

Excalibre and Proventia have previously cooperated on the retrofit of more than 350 Euro 3 Tridents and Darts to the Euro 5 standard.
