Which type of Auxiliary Power Unit is best?

Diesel-powered APUs produce virtually unlimited power available to heat and cool. Battery-powered APUs (Electric) have a set run time but come with the advantage of a clean and quieter operation. The average (battery-powered) APU will provide up to 10-12 hours of cabin air conditioning capacity and typically longer for cabin heating.  Diesel-powered Auxiliary Power Units are best suited for Long-Haul applications.

Thermo King’s next-generation Auxiliary Power Unit provides virtually unlimited sleeper cab heating and air conditioning while reducing tractor idling and lowering maintenance costs.

Add an APU Air Tower

Adding an Auxiliary Power Unit Air Tower to the TriPac® air conditioning system will result in improved temperature management and increased driver comfort.

Since cold air is heavier than warm air, the semi-truck APU has to work harder to push the air up above the bunk. The APU Air Tower solves this challenge by improving air circulation and reducing APU run time by up to 22%.
