The Jost SDR diffuser is mounted on the back of the trailer or rigid truck; it compresses air flowing over the roof and pushes the high pressure air into the low pressure area which would normally be created behind the trailer.
The SDR diffuser turns this low pressure area into high pressure area smoothing the air flow to reduce drag, this makes the workload lighter on the truck to easily maintain higher speeds and reduce fuel consumption. The SDR diffuser has no moving parts and requires no maintenance and can be fitted to any box type trailer or rigid truck body.
The Jost SDR diffuser can be installed to new or existing rigid truck bodies and reefer type trailers, the installation should take no more than an hour. Once the turbulent low pressure zone is created at higher speeds it drags the truck and trailer back.
In order to keep a constant speed more power and more fuel will be needed to overcome this drag. Other advantages of the Jost SDR diffuser includes a more stable vehicle, the SDR also supresses dust and rain spray increasing visibility and safety for other road users. The rear end of the trailer stays cleaner on vehicles fitted with the SDR.
Where will the Jost SDR diffuser give the best return on investment?
The Jost SDR diffuser starts working at 40km/h, but gives the best results at 80km/h. In other words, a long distance line haul application is where the Jost SDR will give the largest return on investment.
The first Jost SDR diffuser fitment was done at JMR Trailer Service Centre in Alrode for Vaal Milling by Gert de Lange JMR Alrode Workshop Manager. The first installation with training took less than an hour and future installations are expected to take no more than half an hour to complete. Vaal Milling will be fitting another 2 trucks with the SDR002D-R in the next two weeks as the vehicles are made available to JMR for fitment.
Fuel consumption has a major effect on the profitability of running a transport business and fuel savings will directly benefit the bottom line. We will be keeping a close eye on consumption and we expect to see some comparative figures from March/April 2013. Watch this space for updates and further information.
