Stainless steel tanker trailers have characteristics that cause drag: an inevitable gap behind the tractor and ahead of the tank’s nose, where turbulence forms, plus fenders, walkways and ladders that grab at the air.
Like all economy-minded managers, the fleet’s executives look for ways to save fuel and found one with a new product from FlowBelow Aero.
The device includes quick-release wheel covers and a pair of fairings installed between and behind the wheels of a tractor’s tandem. They control the complex airflow around the otherwise exposed wheels, and beneath the trailer’s forward fenders. FlowBelow said its testing showed the patented AeroKit system reduces aerodynamic drag and improves the fuel efficiency of a rig by 2.23%, typically providing an ROI for long-haul trucking fleets in one year or less.
Indian River’s in-service tests on four tractors showed even better results: more than 3% higher fuel economy versus tractors without the kits, said Mark Gressett, the fleet’s safety director.
“We tested the AeroKit in our fleet for over seven months, starting in January specifically to test the product’s winter durability and performance,” he said, noting that there are limited options for improving the aerodynamic performance of a tanker trailer. “We were impressed with the product’s durability, ease of use, fuel efficiency performance of over 3% and investment payback in less than one year.”
Controlling air flow should also reduce water spray and improve visibility, but for Indian River “the main thing is the fuel economy,” he said. “We found it worthwhile. It exceeded our expectations.”
Other benefits of The FlowBelow Tractor AeroKit™ include:
- Proven to reduce fuel consumption by 2.23%
- One year ROI for long-haul fleets
- Complimentary performance when used with trailer aerodynamic devices
- Compatible with all tractor OEMs
- Impact resistant at extreme temperatures
- Fits dual and super single tires
- Tool-free, instant access to wheels
- One hour installation (no drilling or welding)
- Great strength to weight ratio
- Designed alongside large fleet managers
- Works seamlessly with snow chains
- Wheel covers available in a variety of colours (black, white, grey, metallic silver, brushed chrome, and polished chrome)
An AeroKit™ retails for $1,800, but with volume pricing, the fleet is paying less than that.
