Thermo King launches all-electric auxiliary power unit



Thermo King, maker of transport temperature control solutions for a variety of mobile applications and a brand of Ingersoll Rand, debued its new all-electric TriPac Envidia auxiliary power unit (APU) at the North American Commercial Vehicle Show (NACV). The TriPac Envidia is an environmentally clean, reliable APU that delivers the extended run-time, without tractor startup. Because there is no diesel engine, the TriPac Envidia is significantly quieter and requires minimal maintenance, according to Thermo King.

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 in-cab comfort.

In addition, the TriPac Envidia was engineered to deliver the fuel and maintenance-cost savings associated with reduced engine operation, Thermo King stated. 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;
• Full discharge of the auxiliary power-pack batteries before switchover, to minimize depletion of tractor batteries during HVAC operation; and
• 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.

Thermo King’s TriPac Envidia meets anti-idle and anti-emission regulations nationwide, including California Air Resources Board (CARB) requirements, the manufacturer reported. The all-electric APU will be available for purchase in early 2018.
