Benefits of the Auxiliary Power Unit
Anti-idling laws have become more prevalent across the United States. As a result, fleets are turning to on-board generators, known as auxiliary power units (APUs), to operate heating and air conditioning systems. The industry averages for fuel consumption at idle range from 0.6 gallons to 1.1 gallons per hour. APUs help fleets reduce fuel costs, while still generating power for the amenities and tools drivers need to perform their jobs efficiently.
There are two main categories of APUs: traditional diesel-fueled and electric-powered APUs. A significant advantage to a diesel-powered APU is that when spec’d correctly, it can handle any load drivers throw at it on top of heating and cooling needs. Electric APUs are quieter than diesel, and don’t add another diesel engine to the truck with its additional fuel use and maintenance costs. Both diesel and electric APUs mean added weight and require space on the frame rail or under the bunk.
The key to running a truck with a diesel-powered APU optimally is to regularly schedule oil changes, fuel filters and general preventative maintenance. Electric APUs require a battery swap at some point during the lifecycle to restore the APU’s original capacity. Overall, battery-powered APUs require less handling than diesel from a maintenance perspective.
