MAINTAIN CAB COMFORT
Any auxiliary power unit can heat and cool the cabin and sleeper. But our APU does it better. The actual temperature is set and monitored using a controller conveniently mounted at the lower bunk level. The auxiliary power unit automatically switches between cooling and heating, eliminating the driver’s need to tweak it. Imagine enjoying your off-hours at the comfort level afforded by a climate control found in luxury cars!
BATTERY CHARGER
The truck’s batteries drop in capacity and power quickly, even if they are relatively new. Most drivers begin to worry that the batteries will fail to crank the engine on days with falling temperatures. Our APU automatically starts and charges them to maintain the optimum voltage to compensate for this problem actively. This way, you can drive a truck with reliable batteries regardless of the weather or their age!

Testimonials
We got three auxiliary power units for our trucks and we have never looked back. They are remarkable little devices that allow our trucks to go further while keeping our drivers comfortable. After several months of using the APU units, we have seen our expenses drop and our profits rise, all with the flip of a switch
Their APU unit is very reliable. I’ve never had a problem with my auxiliary power unit. I have the APU serviced once a year when the truck goes in anyway. The APU helps save money on fuel, keep my truck warm, especially when I’m on the road overnight. The maintenance costs are really good. Definitely recommend their APUs.
Speechless! My previous APU was another brand and it cost me a lot of money. I threw it in garbage. I put a Green APU. April 2020 until now. 1240 hours. Just oil change. That’s it! Thank you, Eric! Special thanks to the guys in the shop!
Great staff, they installed my APU the same day, make sure you make an appointment, Eric answered every question I had and bad man did a super professional job installing the unit, I would recommend this place and I will come back for my APU needs.
