Thermo King’s third-generation TriPac diesel auxiliary power unit (APU) is now available for order, boasting improved efficiency and reduced emissions.

Two models are available: an EPA Tier 4 design for most states and provinces; and a model that not only meets the EPA Tier 4 standards, but also California Air Resource Board (CARB) requirements for use there.

The TriPac APU slashes fuel consumption by 75% compared to idling while reducing wear and tear on the main engine.

“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, 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 new APU is the first to offer telematics, according to Thermo King. TracKing telematics comes as an option and can communicate running hours, cabin temperatures, and fuel tax reporting information. It also enables real-time software updates, alarms and maintenance reminders.

The new generation TriPac also comes with an updated controller and in-cab digital user interface, for an improved driver experience.
