Our story
For truckers, by truckers.
Green APU wasn't dreamed up in a boardroom. It was built by a fleet owner who got tired of auxiliary power units that failed on the road and couldn't be fixed.
Why it exists
A fleet owner who got fed up
In 2011, Arkadiusz "Art" Gruszka was running roughly 200 trucks. Like every fleet owner, he was paying to keep drivers comfortable overnight — and like every fleet owner, he was fighting the APUs that were supposed to do it. They broke in the field. Parts came only from the manufacturer, on the manufacturer's schedule, at the manufacturer's price. When one went down in the wrong place, a truck sat.
So he built the one he wished he could buy: a diesel APU with real cooling power, a proven Kubota engine, and a parts list you can fill at any automotive parts store. No proprietary lock-in. No waiting on a dealer network. Something any diesel shop in the country could keep running.
Fifteen years and more than 10,000 units later, that's still the entire idea. Green APU is family-owned and operated, designed and assembled in the USA, and backed by technicians who answer the phone 24/7 — because the people who build it know what it's like to be the one stuck on the side of the road.

Made in the USA
We don't just sell them. We build them.
Green APUs are designed and assembled at our facility in Lemont, Illinois — from CNC-machined components to final assembly and testing. The 3-cylinder Kubota engine is the only major part sourced outside the United States.
Building it ourselves is why we can stand behind it the way we do: a 2-year, unlimited-hours warranty and support that doesn't end when the sale does.
