The role of a tractor air conditioner is not only to lower air temperature in the cabin, but to provide a more comfortable environment when working in hot conditions.

APU units are good news for the trucking industry. Kind of like an inverter system but more heavy duty. It is a small, efficient motor that is capable of producing the power needed to keep the heating or cooling systems running, and operate interior appliances without the need to run the truck’s engine. For those asking, How does an APU work? It is mounted on the side of the truck just behind the sleeper cab for convenience to access for fueling.
