Electric APU with industry leading power and performance for superior driver comfort

About TriPac Envidia

Clean, quiet comfort

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.

Serious fuel savings

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.

Unmatched support

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.
