Joining Forces To Reduce Emissions

National Express West Midlands Bus Modifications in Partnership with Grayson Thermal Systems and HJS Emission Technology.

Joining forces to reduce emissions.

Birmingham based company Grayson Thermal Systems have partnered with HJS Emission Technology to modify 637 National Express buses within the West Midlands fleet. In readiness for the emission zone regulations coming into force in the Birmingham city centre this coming July 2020; the joint venture will see EURO 3, 4 & 5 rated buses converted to Euro 6 CVRAS standard for compliance in the Birmingham, Coventry, Walsall and Wolverhampton areas.

Both GTS and HJS technical departments have worked closely to find the very best solution for optimisation of these National Express West Midlands vehicles and will now fit the innovative GTS eDrive Electric Fan System and HJS SCRT Real-Blue after treatment system with integrated telematics over a rigorous schedule of 20 buses per week up until the end of this year.

The GTS Edrive electric fan cooling system is designed and manufactured at the GTS Aluminium facility in Tyseley Birmingham.

Ian Hateley, GTS Group Aftermarket Director comments ‘The Edrive system reduces the parasitic load on the engine, therefore aiding the management of thermal performance from the charge air system. This in turn helps to increase exhaust pipe temperature, thus aiding the reduction in emissions’ 

The HJS supplied after-treatment system monitors emissions through the on-board telematics. This broadcasts the status and performance of the HJS system in order to ensure the highest level of in service system reliability.

Fleet operators are under an immense amount of pressure to maintain service levels and reduce their environmental impact in order to comply with Clean Air Zones (CAZ’s). The HJS SCRT provides operators with a cost effective retrofit solution for CAZ compliance with ongoing system “real time” status and performance available to view using the HJS Remote Emission Monitoring (REM) system.

The modifications will take place at the newly opened GTS service centre in Tyseley where additional capacity has been created to accommodate a 14 bay workshop. All buses are then tested and verified at the Millbrook proving ground upon completion.

This represents an element of significant investment into ‘clean air’ projects throughout the West Midlands with National Express West Midlands buses set to be amongst the cleanest in the area. The fleet will be 80% Euro VI by January 2020 and will be 100% Euro VI by April 2021.

Not only will these adaptations be good for the environment and our health, it has also served to provide over 25 extra jobs in the local Birmingham area through GTS employment, with additional positive impacts being seen further afield  too.

This is a great continuation of a 20 year relationship between National Express West Midlands and Grayson Thermal Systems with both parties pleased that the HJS team are on-board to see this project through to a successful completion and in the hope of more collaborative projects like this to come.
