Keeping city streets free from airborne toxins has become a major concern for the UK in recent years. Van fleets in particular have been targeted, leaving many looking for ways to reduce their emissions output. HJS Emission Technology argues the case for retrofitting SCR systems.
The UK Government has introduced Clean Air Zones within major cities across the UK to target air quality issues and improve public health. Clean Air Zones aim to reduce all types of air pollution, including nitrogen dioxide and particulate matter. The Government’s ‘National Air Quality Plan’ requires a number of other UK cities to follow by 2020.
The UK’s most immediate air quality challenge is to bring roadside concentrations of nitrogen oxides (NOx) within legal limits in the shortest possible time. The aforementioned ‘National Air Quality Plan’ requires the majority of vehicles travelling within the zones to meet exhaust emission standards for NOx and particulate matter (PM) or pay a daily charge. If a vehicle does not meet the required standards and the daily charge is not paid, a Penalty Notice Charge will be issued to the operator/owner.
These tighter new emission standards require all diesel powered vans and minibuses to comply with Euro VI emission standards in order to operate freely within these zones. One option that some operators may find appealing is the retrofitting of an alternative exhaust system. HJS Emission Technology provides such a solution.
HJS is developing a retrofit SCR exhaust system that offers fleet managers and vehicle operators an extremely cost effective upgrade solution, which will enable them to comply with Euro VI emission standards at the fraction of the cost of replacement vehicles.
The retrofit HJS SCR system offers ULEZ/LEZ and CAZ compliance for a large range of Euro V light commercial chassis applications, including the Ford Transit, Mercedes Sprinter, Fiat Ducato, Volkswagen Crafter, Vauxhall Movano and Renault Master, plus others.
Mark Cooper of HJS UK said, “HJS has already retrofitted hundreds of UK buses with SCR technology, upgrading emissions to Euro VI standards. The cost of replacing the whole fleet is a huge expense and HJS can upgrade vehicles at the fraction of the cost of buying replacement vehicles. The van market is a new exciting business area for us here in the UK and we are ahead of our competitors in this market!
“Euro V light commercial vehicles are already equipped with a DPF system for the reduction of particulate matter and this element of the exhaust system is retained. The SCR system supplied by HJS consists of an additional underfloor catalyst, an AdBlue tank, engine sensors and an independent control unit. The SCR system operates by injecting an ammonia-based solution (AdBlue) directly into the exhaust gas stream which mixes with the dirty exhaust gases converting nitrogen dioxide emissions into harmless water and nitrogen.
“The system is manufactured to the highest German quality standards and will be certified imminently for these applications in order to meet all of the requirements set out by the Energy Savings Trust’s Clean Vehicle Retrofit Accreditation Scheme (CVRAS) and ULEZ in London.
“Our specialist team has over 30 years’ experience in the manufacturing and development of exhaust after-treatment systems. SCR technology has been installed into thousands of vehicles worldwide, helping to reduce harmful emissions in towns and cities.”
