When you are involved in long-haul trucking, your truck becomes your mobile home, where you work, sleep, and rest for days or weeks at a time. It is essential to ensure comfort, safety, and well-being during these extended periods while managing rising fuel costs and staying compliant with emissions regulations. Therefore, this is where a truck APU (Auxiliary Power Unit) becomes a lifesaver, providing a reliable power source to improve your quality of life on the road.
You may be wondering: what exactly is an APU unit on a truck, and how can it transform your trucking operations? Whether you are a seasoned driver looking to upgrade your rig or a fleet manager seeking cost-effective solutions, understanding the benefits of truck APU is crucial for modern trucking success.
In this article, we will guide you through the basics of Truck Apu, including how it works, its key benefits, and how to choose the right APU system for your specific needs.
What is an APU Unit for Truck?
A truck APU is a compact, dependent device mounted on trucks. It operates as an efficient generator, providing auxiliary power when the main engine is turned off. When parked during rest periods, the device powers essential systems, such as air conditioning, heating, lights, phone chargers, microwaves, and refrigerators, allowing drivers to maintain comfort and safety without idling the truck’s main engine.
Types of APU Units for Trucks
Truck APU units primarily come in two main types: diesel-powered and electric.
- A diesel APU is typically mounted outside the truck, often just behind the cab, for easy access and refueling. It taps into the fuel supply of trucks to generate power.
- An electric truck APU operates with minimal emissions and requires less maintenance, making it an environmentally friendly choice for modern trucking operations.
Benefits of Using APU Unit for Truck
There are many APU benefits. Here are the top six benefits of installing an APU unit on your truck:
Benefit 1: Reduced Fuel Consumption
Fuel consumption costs occupy a significant portion of the operating cost for fleets and owner operators. While idling the engine maintains a comfortable environment for drivers, it consumes energy excessively. An hour of idling time consumes about one gallon of diesel fuel, whereas a diesel-based APU unit for truck consumes far less — about 0.25 gallon of fuel per hour.
On average, a truck idles between 1800 and 2500 hours per year. Assuming 2,500 hours per year of idling and diesel fuel at $2.80 per gallon, a truck spends $7,000 on idling per truck. If you manage a fleet with hundreds of trucks, that cost can quickly jump up to tens of thousands of dollars and more every month. With a diesel APU, a savings of more than $5,000 per year can be achieved, while an electric APU might save even more.
Benefit 2: Extended Engine Life
According to the American Trucking Association, one hour of idling per day for one-year results in the equivalent of 64,000 miles in engine wear. Since truck idling can produce sulfuric acid, which might eat away at the engine and vehicle components, the wear and tear on engines increases dramatically. Moreover, idling will lower the in-cylinder temperatures combustion, causing buildup in the engine and clogging. Therefore, drivers need to use an APU to avoid idling and reduce engine tear and wear.
Benefit 3: Minimized Maintenance Costs
Maintenance costs due to excessive idling are far higher than any other possible maintenance costs. The America Transportation Research Institute states that the average maintenance cost of a Class 8 truck is 14.8 cents per mile. Idling a truck leads to costly expenses for additional maintenance. When with a truck APU, service intervals for maintenance extend. You don’t have to spend more time in the repair shop, and the costs of the labor and equipment parts are significantly minimized, thus lowering the total cost of ownership.
Benefit 4: Regulations Compliance
Because of the harmful effects of truck idling on the environment and even public health, many major cities worldwide have implemented anti-idling laws and regulations to limit emissions. The restrictions, fines, and penalties vary from city to city. In New York City, idling of vehicle is illegal if it lasts over 3 minutes, and vehicle owners would be fined. CARB regulations stipulate that drivers of diesel-fueled commercial motor vehicles with gross vehicle weight ratings greater than 10,000 pounds, including buses and sleeper berth equipped trucks, not idle the vehicle’s primary diesel engine longer than five minutes at any location. Therefore, to comply to the regulations and reduce inconvenience in trucking services, an APU unit for truck is a better way to go.
Benefit 5: Enhanced Driver Comfort
Truck drivers can be efficient and productive when they have proper rest. After a day of long-haul driving, you pull into a rest stop. Though the sleeper cab provides plenty of space to rest, the noise of running the truck engine can be annoying. Having an APU unit for truck offers a quieter environment for a good rest while functioning for charging, air conditioning, heating, and engine warming demands. It increases the home-like comfort and makes your driving experience more pleasing. Ultimately, it will help boost the overall productivity of the fleet.
Benefit 6: Improved Environmental Sustainability
Truck engine idling will produce harmful chemicals, gasses, and particles, significantly resulting in air pollution. Every 10 minutes of idling releases 1 pound of carbon dioxide into the air, worsening the global climate change. While diesel APUs still use fuel, they consume less and help trucks reduce their carbon footprint compared to engine idling and improve environmental sustainability.
Upgrade Truck Fleets with APUs
Installing an APU unit on your truck is highly recommended, as it enhances driver comfort and operational efficiency while helping to meet environmental regulations. But how do you choose the right APU for your fleet? Here are the key factors to consider:
- Power Efficiency: Evaluate the power requirements of your fleets first. A diesel-powered APU may be adequate for basic needs. However, if your operations demand more power for advanced equipment, an all-electric truck APU might be the better choice.
- Maintenance Requirements: As Diesel APUs have multiple mechanical components, they require regular maintenance, including oil changes, fuel filter replacements, and preventative servicing. In contrast, electric APUs for trucks involve minimal maintenance, thus reducing downtime and overall maintenance expenses.
- Warranty and Support: Always check the warranty terms and after-sales support. A robust warranty can safeguard your investment and ensure you get timely service if any issues arise.
- Budget Considerations: While electric APUs often come with a higher upfront cost, they usually offer significant long-term savings due to lower fuel consumption and reduced maintenance needs. Diesel APUs are cheaper to initial installation but can result in higher operational costs over time.
- Ease of Use: Electric APUs are typically easier to install and operate. Many models also feature intelligent management systems, allowing seamless control from the cab.
In summary, electric truck APU units have gained increasing popularity in the transportation industry. They provide quiet, low-maintenance operation, extended hours of air conditioning, and help fleets meet stricter emissions regulations, making them a wise investment for modern trucking operations.
