Montracon claims new aerodynamic trailer will save operators 8% in fuel costs

Trailer and body builder Montracon claims its new aerodynamically designed box trailer, with curved roof, tapered sides and vortex generators, will deliver 8% fuel savings for operators.

The FST (fuel saving trailer) design includes curved roof, rearward sloping trailer floor, and the sides of the trailer taper 80mm (40mm each side) at the back with a line of vortex generators at the rear edges of the roof and sides.

Paul Mead, sales and marketing director at Montracon, says the taper affect and vortex generators deflect air flow into the immediate trailer wake, reducing the partial vacuum or base pressure drag (suction) that develops with vehicle speed.

FST also has an aerodynamic front bulkhead and aerodynamic side skirts to channel air flow along the trailer sides. "We have been looking at various designs but decided on this one as it provides all the fuel economy benefits without any operational drawbacks in terms of load capacity or positioning of pallets."
