Cross-Flow Vortex Traps (US Patent 6986544)
How They Work

The Cross-Flow Vortex Traps create a series of trapped vortices, oriented vertically on the front face of the trailer. The trapped vortices decrease the pressures acting on the front face of the trailer and reduce drag. This technology has undergone extensive road testing. Fuel savings of between 4 to 5 percent were demonstrated in the wind tunnel and road tests of this technology. For an in-depth analysis of the road tests of this technology download the SAE technical paper (628kb pdf).

Calculate your potential cash savings!

All SOLUS fuel Savings devices have undergone extensive evaluation on the Solus/ODU Representative Heavy Truck (SO RHT) wind tunnel model in the Langley Full Scale wind tunnel. SAE Type II road tests are scheduled for Sping '06 to further document fuel savings.
