TriPac Envidia® All-Electric APU

All Electric APU TriPac Envidia

All-electric APU with industry leading power and performance for superior driver comfort.

We’re proud to offer a clean, reliable all-electric auxiliary power unit (APU) that not only saves fuel but delivers unmatched driver comfort previously unavailable in an electric unit. Meet the 2nd generation TriPac Envidia, the envy of the trucking world. 

Product Features


With no diesel engine, the TriPac Envidia runs clean and emission-free and is significantly quieter than engine-based APU systems. Thermo King designed the TriPac Envidia to meet nationwide anti-idle and zero-emission regulations, including CARB requirements.


The TriPac Envidia is an all-electric, battery-based APU system, which means significant savings on fuel. By reducing the operation of the tractor engine, the system delivers big cost savings on maintenance.


The TriPac APU has the support of the nationwide Thermo King dealer network, which provides expert installation, factory-certified technicians, and genuine OEM parts at over 200 locations across North America.

The All-Electric Benchmark for Driver Comfort

In the past, users of all-electric APUs had to contend with limited runtime and power, which negatively impacted driver comfort, rest, and safety. Those days are over, thanks to TriPac Envidia.

  1. Competitive electric runtime without tractor startup.*
  2. Effective heating and cooling for maximum comfort.
  3. The power to run the devices that make the sleeper cab feel more like home.
  4. Quiet operation for uninterrupted rest.
