TriPac® Evolution Diesel APU

truck apu diesel unit

The industry-leading APU that delivers lower operating costs and superior driver comfort.

Built on the industry-leading TriPac auxiliary power unit (APU) and supported by the Thermo King dealer network, the TriPac Evolution raises the bar even higher with unrivaled performance, low operating costs, easy operation, and peace of mind.

The semi APU TriPac Evolution was not only designed to meet Tier IV EPA final regulation requirements, it leverages patented technologies that drive unit efficiency and user productivity. Its performance is uncompromised. The operational savings are real. 

TriPac Evolution Product Features

MAXIMUM DRIVER COMFORT

Drivers spend long days away from home on the road, and a comfortable sleeper is important for well-rested and safe drivers. The TriPac Evolution brings the comforts of home to wherever home is for the night. An APU system for trucks can offer virtually unlimited cooling and heating and the power to run the appliances and devices drivers require.

Attracting and retaining the drivers is a challenge but offering an APU unit for semi trucks can be a key recruitment and retention tool. There’s a reason why drivers ask for TriPac Evolution by name.

SAVE MONEY

No matter the current price, fuel costs represent a significant portion of your operating expenses. Adding the semi truck APU TriPac Evolution will significantly reduce your fuel consumption - by up to 2,500 gallons per year.* The TriPac Evolution: cash flow positive from the beginning.

* Based on actual customer experiences. Reduced costs experienced by individual customers will vary.

REDUCED TRACTOR IDLING

Idling the tractor engine to provide cab power causes excessive engine wear and run time, increases maintenance costs, may lower the residual value of the tractor, and releases unnecessary emissions into the environment. Adding a truck auxiliary power unit, like the TriPac Evolution, virtually eliminates tractor engine idling, putting more money back in your pocket.

Choose the number one truck APU in the industry

The TriPac Evolution truck APU unit has virtually unlimited heating and cooling and a control system to accurately diagnose issues. The control system is flashloadable and includes a data logger. Diagnostics are improved with 22 alarm codes, and the charging system has amperage-based decision making. The system gives flexibility to users, allowing customers to focus on fuel consumption, driver comfort, or battery life.

2,000-Hour Maintenance Interval

TriPac Evolution was designed with an unequaled 2,000-hour maintenance interval, allowing for maintenance to be performed typically only once per year, aligning better to the tractor maintenance schedule, saving time and eliminating additional downtime for APU maintenance.

Actual maintenance intervals on the TriPac Evolution are even further extended when the auto start/stop function is taken into account. This feature turns the truck APU on only when needed, saving fuel and reducing the number of hours the unit runs compared to the competition.
