Green APU

Auxiliary Power Units for Semi Trucks:

AAA Trailer Services recently expanded to Granite City, IL with a fresh new facility, custom built to our needs for the future. We incorporated solar panels on the roof to power our entire operation in the most sustainable way. Many of our customers are considering similar efficiency and sustainability upgrades.

We are a full service dealer for Green APU in the Saint Louis Metro Region, offering sales, maintenance, repairs and parts to our transportation customers.

Auxiliary Power Units have become more common and we are pleased to offer a more sustainable option in line with our values. Auxiliary power from Green APU utilizes readily available components, are made in the USA and efficiently conserve fuel to offer the most environmental APU currently available.

Green APU is the Most Versatile, Convenient, and Durable Auxiliary Power Unit for Semi Trucks on the Market.

The Comforts of Home, Away from Home

Whether you are in the heat of summer, or the dark, cold nights of winter, Green APU keeps you comfortable all year long.

Their Auxiliary Power Unit automatically switches between Heat, or A/C depending on the outside temperature. You can also control the climate inside your truck with an easy to reach switch, mounted at the lower bunk level. Enjoy your off hours in total comfort

All diesel truck engines manufactured from 2007 to the present are equipped with a Diesel Particulate Filter (DPF). If this filter clogs, your truck’s engine will not run.

Prevent premature DPF wear, and excessive tractor idling warranty issues with Green APU. Our unit provides all the power you need during off time, without ever having to idle your main engine. (now that’s green and efficient)

Minimize the costs associated with unneeded DPF regeneration or replacement. Let Green APU help you keep more money in your pocket!
