Why the 3rd Generation Diesel TriPac APU?

RXO has partnered with Thermo King to provide best-in-class APUs to drivers. Thermo King’s newest TriPac APU provides a powerful 13,000 BTUs, offering plenty of capacity to power appliances and charge devices to bring the comforts of home to the road. Plus, it has been enhanced to offer 24 months of TracKing® telematics as standard, a new digital color display, and has been built to lower your total cost of ownership.

Available in two models:

  1. Standard model: A 49-state EPA Tier 4 compliant solution for aftermarket installs
  2. Aftertreatment device model: A 50-state compliant solution for CARB and EPA Tier 4 compliant for new OEM or aftermarket installs

TriPac, the APU drivers ask for by name

A TriPac APU consumes approximately 75% less fuel per hour than idling the tractor engine. That’s about 2,500 gallons per year or 10,000 gallons over the typical length of tractor ownership.

Optimize APU performance and eliminate energy waste with TracKing® telematics as standard.  Plus, the no-fuss aftertreatment device (ATD) model is a 50-state compliant solution to meet CARB regulations. That means fewer logistical hoops to jump through since it
is available in every state.

Achieve greater uptime and lower maintenance costs by preserving engine run time for the road. A TriPac APU eliminates unnecessary engine idling, saving engine wear and reducing maintenance frequency.

Reduce your fleet’s climate impact


Installing TriPac APUs on your fleet is a quick and effective way to significantly reduce carbon emissions.


By eliminating rest stop idling, the TriPac APU reduces emissions proportionately to its approximate 75% lower fuel consumption rate. Add ThermoLite® solar panels to reduce fossil fuel emissions even more. Calculating and sharing your climate contributions with your customers, drivers, and various communities is simple with available TracKing telematics.
