Thermo King on Monday introduced its all-electric auxiliary power unit (APU) at the North American Commercial Vehicle Show (NACV) in Atlanta.
Thermo King says the TriPac Envidia is a quiet, environmentally clean APU that delivers the longest run-time in the industry without tractor startup.
The introduction of the emission-free unit is a milestone for Thermo King, says North America Vice President and General Manager Dane Taival. The new unit features a simple in-cab controller allows drivers to select cooling, 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.
The unit’s patented battery management technology also provides individual charging and discharging management for each battery; a three-stage charging profile to optimize performance and extend the life of its NXT dry cell technology battery; and a full discharge of the auxiliary power-pack batteries before switchover, to minimize depletion of tractor batteries during HVAC operation, the company says.
