TriPac Evolution Diesel APU

The diesel TriPac® Evolution APU is designed to offer increased driver comfort, greater fuel savings, better driver recruitment/retention, idle reduction, lowered maintenance costs and higher tractor residual value. 

Make your TriPac APU more efficient by pairing it with a ThermoLite solar panel, damper kit, and air tower. 

Increase APU Efficiency by up to 51%

Thermo Light Solar Panels

ThermoLite Solar Panel - 110W

Increase APU Runtime by up to 30%

Solar panels allow the APU to have healthier batteries from improved Depth of Discharge (DOD). They offset daytime stress on the APU HVAC.

Extend APU Uptime

Reduce costly downtime and support sustainability plans with a ThermoLite solar charging system.

Damper Kit

Damper Kit

Extend APU Runtime by up to 10%

Designed for OEM. APU airflow distributed to the cab area is reduced up to 10% when some of the aiflow backflows through the OEM HVAC system. Reducing this lost aifrlow is the key.

Eliminates Backflow

By automatically closing the OEM's HVAC air inlet opening when the system is running, the APU system can now generate 100% airflow. 

Air Tower

Air Tower

Increase APU Runtime by up to 11% With One Tower

Even air distribution and optimal air circulation increase efficiency. The air tower increases the APU efficiency by improving the air circulation by evenly distributing it. Add an air tower where the OEM duct is not available. 

Increase Comfort

Adding an APU air tower to the TriPac air conditioning system will result in improved temperature management and increased driver comfort.
