Thermo King demos all-electric APU

Mid-America Trucking Show 2019 coverage

Thermo King showcased its all-electric TriPac Envidia auxiliary power unit at this year’s MATS, with the system in action on a full-size semi on the show floor.

The TriPac Envidia is an environmentally clean, reliable APU that delivers the longest run-time in the industry, without tractor startup, offering unmatched driver comfort previously unavailable in an all-electric unit, according to the company.

Historically, battery-powered APUs provided insufficient run-time and limited power. With the introduction of the TriPac Envidia, Thermo King now offers a green solution with the longest all electric runtime in the industry, without tractor startup. Because there is no diesel engine, the TriPac Envidia not only runs clean, but it is significantly quieter and requires minimal maintenance.

“The introduction of this emission-free technology is a significant milestone for Thermo King, and it reaffirms our commitment to sustainability through innovation,” said Dane Taival, vice president and general manager, Thermo King North America. “Our Thermo King employees and dealer network endlessly strive to offer the absolute best solutions for our customers, and I’m confident the TriPac Envidia will deliver both superior performance and satisfaction for users looking for an all-electric APU.”

The unit’s simple in-cab controller allows drivers to select the desired function of the system—cool, fan or heat modes. The controller also indicates the battery charge level, and allows drivers to adjust the fan speed and cab temperature to deliver optimal in-cab comfort.

In addition, the TriPac Envidia was engineered to deliver the fuel and maintenance-cost savings associated with reduced engine operation – a feature that APU users have come to expect. The unit’s patented battery management technology also provides: 

• Individual charging and discharging management for each battery

• Three-stage charging profile to optimize performance and extend the life of its NXT dry cell technology battery; and

• Full discharge of the auxiliary power-pack batteries before switchover, to minimize depletion of tractor batteries during HVAC operation.

Whether supplementing with solar, or utilizing power options like battery or shore power, the TriPac Envidia offers choices for drivers to tap into the power they need to stay charged. The Thermo King TriPac Envidia system meets anti-idle and anti-emission regulations nationwide, including California Air Resources Board (CARB) requirements.
