REDUCE COSTS DUE TO SKIRTS ON UNUSED TRAILERS AND THE COST OF EQUIPPING ENTIRE FLEETS - ASK US ABOUT "RADIUS AS A CARTRIDGE" AND FOR INTERMODAL QUICK CONNECT / DISCONNECT THE "POINTS ON MOUNT"

RADIUS semi side skirt comes out on top. First and second generation “traditional side skirts” shelter the rear trailer wheels from incident air, but do not allow optimized slipstream performance. The graphical representation below is a summary based on results posted on competitive web sites versus aerodynamic testing conducted on RADIUS in 2011. Testing in 2014 supports the efficacy of RADIUS and garnered SmartWay status.

The results are from the most conservative rigorous testing currently available - 0 to 9 degree yaw rolling road wind tunnel analysis. -And, in accord with our commitment to continuous improvement, we have been back to the tunnel to qualify our 20' and 23' long skirts - both are EPA SmartWay Verified!

Airflow - The way nature intended it to be…

Taking cues from natural shapes, RADIUS employs two large air flow directing surfaces.  The unique geometry allows air to smoothly transition from turbulent behind the tractor wheels and from the exterior of the tractor to a more laminar stream. Curved from beginning to end, RADIUS surfaces end flush with the side of the trailer. The effect of air "sticking" to the RADIUS surface combined with pressure exerted from the outside air stream causes a generally inward airflow after the trailer wheels. The net effect is better slipstream performance and economy gain.

First and second generation skirts, older technologies, are composed of straight skirt sections, either single plane or multi-plane, positioned parallel to the trailer sides, angled outward, or a combination of the these orientations. In addition to not being as effective as RADIUS, these earlier generations require more complex materials and greater cross sectional thickness to attain the required rigidity in the air stream.

 Unique design allows thin cross-section, weight, and flexibility

 

 

Independent testing results are clear: RADIUS generates a substantial reduction in fuel consumption. Typical users would reduce annual consumption by more than 1,000 gallons for 125,000 traveled miles**.
