Available features of the two new auxiliary power unit models include TracKing telematics, innovative emission reduction technology, and improved operational efficiency

Thermo King recently introduced its third-generation diesel TriPac auxiliary power unit (APU).

Building on the success of the TriPac Evolution, the new model provides the same comfort and performance customers expect, but with added enhancements that reduce emissions, monitor unit performance, and increase profitability, Thermo King said.

The third-generation TriPac APU is available now in two different models to add flexibility and help customers meet emission regulations. One model is a 49-state Environmental Protection Agency (EPA) Tier 4 compliant solution for aftermarket installations. The second model includes a new aftertreatment device (ATD) that is 50-state compliant with California Air Resources Board (CARB) and meets EPA Tier 4 compliance for new original equipment manufacturer (OEM) or aftermarket installations. 

The TriPac APU provides added value to customers with ESG targets because it eliminates unnecessary engine idling, which helps lower fuel consumption, Thermo King said. The TriPac consumes approximately 75% less fuel per hour, which equates to 2,500 gallons each year or 10,000 gallons over the typical length of tractor ownership. In addition, it reduces the wear and tear on the larger tractor engine and improves resale value.

“The progression of our TriPac APU solves many challenges that fleets face today because it helps maximize comfort for drivers while also increasing the fleet’s return on investment and addresses emission regulations and connectivity,” said Charlene Vance, APU portfolio leader for Thermo King Americas. “In fact, with increased fuel costs and a focus on reduced emissions, APUs are being utilized in more than just Class 8 sleeper cabs and gaining popularity in adjacent markets such as large service vehicles and on heavy construction equipment such as cranes.” 

The next-gen TriPac APU is the first in the refrigerated transportation industry to include telematics capabilities for an APU. TracKing telematics now is an available option on both new models. Adding telematics provides the data needed to have a clear line of sight to the unit’s run hours, cabin temperatures, and fuel tax reporting. Real-time software updates, alarms, and maintenance reminders help ensure the APU runs smoothly.

The new TriPac APU also features an updated controller and in-cab digital user interface, providing a premium, modern driver experience. The new digital controller provides drivers with greater control over their comfort and APU operations with large cabin temperature readings, function icons, and toggling menus.
