FAQ about APU for Trucks

What are Auxiliary Power Units?

An Auxiliary Power Unit (APU) is a device that is attached to large vehicles, such as transport trucks, to operate various systems. The device allows the vehicle to be turned off while still accessing the heating and cooling systems and secondary accessories. This saves on fuel because the vehicle does not need to be idling as it would without the APU installed. Less fuel consumption equates to more money saved and fewer resources wasted.

What's the purpose of APU?

An APU is designed to save money on fuel and at the same time, offer an alternative energy source for a vehicle so that fuel resources are not needlessly consumed. As a vehicle’s parking brake is set, the APU is engaged to operate the systems that would normally be operated by the engine. With the engine running much quieter, less fuel is used saving the truck operator money on the cost of fuel.

A bigger purpose is than cost saving is to be environmentally friendly. Lower fuel consumption means fewer carbon emissions into the atmosphere and less strain on natural resources.

How does diesel APU work?

A diesel APU uses diesel fuel to provide power in various capacities when the vehicle is parked. The unit burns between 0.1 and 0.5 gallons of fuel per hour to power HVAC systems, hotel, or other electrical needs. It can even provide standard AC power when used through a generator or an inverter, reducing the need to burn more fuel.

What are the benefits of diesel APU?

A diesel APU provides a clean alternative energy source for heating, cooling, and AC power, saving money on fuel consumption.

Because diesel APUs are designed to operate in extreme heat or cold weather, they ensure reliable starts while also maintaining the internal cab systems.

As an APU uses very minimal fuel, it allows for almost unlimited use for heating, cooling, and AC power when needed.

How much fuel does an APU save/use?

Typically, a truck may consume approximately one gallon of diesel fuel per hour of idling time. At 2400 hours of idling per year on a vehicle, with the cost of diesel at $2.80 per gallon, that’s a fuel cost of $6720 per year for a truck to idle.

With an APU, however, that cost can be slashed by 90% by burning through only about 0.1 gallons of fuel per hour. That would amount to a total cost of $672 spent on fuel for a truck to idle over the course of the year.

Does GREEN APU need to be serviced?

Maintenance for your Green APU is recommended every 600 work hours. This includes oil and filter changes, checking belts, cleaning the HVAC system, and other important service checks. All combined, the maintenance service will keep your truck and your APU operating at peak efficiency for optimum fuel savings.
