Why Choose Green APU?

The Most Versatile, Convenient, and Durable Auxiliary Power Unit for Semi Trucks on the Market

Maintain Truck 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!

Semi Truck 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!

Engine Preheat

The truck’s diesel engine is hard to crank in cold temperatures. Our auxiliary power units for semi-trucks counteract the cold weather problems. Green APUs automatically start and warm the truck’s main engine if the coolant drops below 32F. This process ensures that the truck starts quickly, even after a few days in frigid weather.

Truck Jumpstart

The truck’s batteries can quickly be depleted if left unattended. Electrical drain or driver convenience accessories, such as refrigerators, can deprive main batteries of the necessary cranking power. Fortunately, our APU can start using very little battery power – a passenger car can provide a jump start for it if need be. In turn, it can charge mostly drained batteries up to the necessary cranking power in as little as 20 minutes, preventing costly service calls.

Conserve Your DPF

All diesel truck models 2007 and newer are equipped with a Diesel Particulate Filter (DPF). This system can clog and shut down the main engine. Additionally, some truck manufacturers will void your tractor’s warranty if the idle time exceeds about 15%. DPF repairs cost anywhere from $800 for a regeneration service to over $6,000 for a replacement job. Our auxiliary power unit avoids this problem because it eliminates the need for the main engine idle.

General Advantages of Using Auxiliary Power Units

Ever since the strict enforcement of the US’s idling restrictions, many in the transportation industry have paid attention and equipped their semi-trucks with APUs. It is not just that; the advantages of getting one also attract more truckers to buy it. Auxiliary power units for semi-trucks are a great way to save money in the long run. The main engine is not worn out when using an APU, your DPF filter does not get clogged, and your truck will have a better performance on a per-hour basis too. The auxiliary power unit in semi-trucks also reduces the truck hours used, which will help prevent your warranty from getting void.
