Both GTS and HJS technical departments worked closely to find the very best solution for optimisation of these National Express West Midlands vehicles and fitted our innovative GTS Electric Fan Cooling 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 that calendar year.

Ian Hateley, GTS Group Aftermarket Director, explained: ‘Our Electric Fan drive 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 onboard 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 the ongoing system “real-time” status and performance available to view using the HJS Remote Emission Monitoring (REM) system.
