Thermo King introduced its third-generation diesel TriPac Auxiliary Power Unit (APU), adding enhancements to reduce emissions, monitor unit performance, and increase profitability, according to the company.

The new APU is available in two models:

•  A 49-state Environmental Protection Agency Tier 4 compliant solution for aftermarket installations.

• A model with a new after treatment device that is 50-state compliant with California Air Resource Board regulations and meets EPA Tier 4 compliance for new original equipment manufacturer (OEM) or aftermarket installations.  

The Thermo King TriPac APU consumes about 75% less fuel per hour, 2,500 gallons each year, or 10,000 gallons over the typical length of tractor ownership, according to the company.

“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 a statement. “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.”  

TracKing telematics is now an available option on both third-generation 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.
