ATDYNAMICS EcoSkirt
Optimum aerodynamic performance

ATDynamics EcoSkirt® works to improve tractor-trailer fuel efficiency by reducing aerodynamic drag that occurs under the trailer where air hits the trailer’s rear axles. The side fairings help to streamline and guide the air around and to the back of the trailer.

The most competitive and profitable fleets combine EcoSkirts® with ATDynamics TrailerTail® technology to address the two largest areas of aerodynamic inefficiency in their trailers. The aerodynamic benefits are additive when using TrailerTails® and EcoSkirts® together and can deliver 9 - 12% fuel savings, depending on the product configuration.

PERFORMANCE

OPTIMUM AERODYNAMIC PERFORMANCE

ATDynamics EcoSkirts® are engineered to deliver optimal under-trailer aerodynamic benefit.  The patented design and integration of these side fairings with your trailer deliver maximum fuel savings and operational performance.

ULTRA-FLEX, IMPACT RESISTANT PANELS

EcoSkirts® are constructed of ultra-durable and flexible proprietary thermoplastic composite panels similar to the material used in trailer scuff liners.  The material’s cross-woven fibers provide the strength and flexibility for the panels to bend but not break in collisions or contact with under-trailer obstacles.  The skirt panels are highly impact resistant and designed to withstand frequent contact with tough on-road elements such as concrete curbs, steep loading docks and ice banks.

ATDynamics EcoSkirts are also extremely lightweight for minimal impact on payload.

SMART DESIGN AND ENGINEERING

One of the key distinguishing features of ATDynamics EcoSkirt® technology is the patented flexible strut design.  Our struts are made of the same flexible thermoplastic composite material as the panels to allow maximum flexibility of the skirt to bend almost completely under the trailer, safely accommodating any under-trailer obstacles encountered with no damage to the skirt panels.  The ultra-flexible panels and brackets are designed to spring back into normal position and shape after clearing the under-trailer obstacle.

COLD WEATHER PERFORMANCE

ATDynamics EcoSkirts® have been proven to operate in all weather conditions with no performance compromises.  The panel material is designed to repel rain, ice and snow and is temperature resistant so it does not expand or contract in extreme heat or cold.  All metal hardware components are made of galvanized steel to prevent damage from rust and salt.  EcoSkirts® significantly reduce road spray in wet, wintry conditions and improve visibility for both your drivers and the public.

UNIVERSAL APPLICATION

ATDynamics EcoSkirt® technology is compatible with all trailer models and is available to be factory installed on new trailer orders or retrofitted to your existing fleet.  Custom options are available for trailer applications requiring access to underside mounted equipment such as hydraulic lift-gate boxes, loading ramps and spare tire carriers.  All skirt options provide 10”-13” of ground clearance.

ATDynamics EcoSkirt® technology offers significant safety benefits to truck drivers and the driving public.  By streamlining the airflow under and around your semi-trailers, side skirts help to stabilize your trailers on the highway, especially in windy conditions, and improve visibility for both truck drivers and surrounding vehicles by reducing road spray off the wheels.  EcoSkirts® also act as a protective and potentially life-saving guard, mitigating the occurrence of under-vehicle accidents with vehicles, cyclists and pedestrians.


COMPLIANCE

The California Air Resources Board (CARB) has adopted the Heavy-Duty Vehicle Greenhouse Gas Emission Reduction Regulation to improve the fuel efficiency of heavy-duty tractor and 53' trailer combinations through fleet implementation of tractor and trailer aerodynamics and low rolling-resistance tires.

The ATDynamics EcoSkirt® provides full compliance with the 2010 CARB regulations as a stand-alone device, tested to deliver 7.4% fuel savings at 65 mph.

In order to meet the CARB regulation, aerodynamic devices must be verified by the US EPA’s SmartWay group using approved fuel efficiency testing methodologies.  Aerodynamic devices are currently verified in either a 1% or 5% fuel savings category.

ATDynamics EcoSkirts are verified by EPA SmartWay in the “Advanced Trailer Skirt” category, delivering over 5% fuel savings.

Motorists in key freight corridors in the United States now see aerodynamic side skirts on a daily basis.  Approximately 40% of the North American trailer fleet is now outfitted with aerodynamic side skirting due to the proven fuel efficiency, operational and safety benefits.

Every side skirt in operation offsets approximately the equivalent annual greenhouse gas (GHG) emissions of one passenger vehicle, every year.

Each ATDynamics EcoSkirt® saves an average of 8 gallons of diesel fuel for every 1000 miles a semi-truck drives.  Every gallon of fuel not burned reduces the amount of carbon dioxide emitted into the air, keeping our air cleaner and reducing our dependence on fossil fuels.

ATDynamics is deeply committed to our mission of rapid commercialization of next- generation freight efficiency technologies that deliver important economic, environmental and social benefits.
