How Do You Install APU on a Semi Truck?

Installing an APU on a semi truck is a great way to save fuel and reduce engine idling time. An APU (auxiliary power unit) is a small engine that runs on diesel, propane or electricity to provide electricity and air conditioning when the truck isn’t running.

An APU installation consists of the APU itself, mounting hardware, wiring and ventilation ducting.

The first step in installing an APU is to choose the right model for your needs. Some models will require professional installation, while others can be installed by the owner. It’s important to consider size, power requirements, fuel type and other features when selecting an APU.

Once you have selected the right model for your needs, you will need to mount it in place. This may require some drilling and cutting of metal in order to fit the unit securely. It’s important to follow all instructions carefully when mounting an APU.

Next, you will need to run wiring from the APU to its various components. This includes connecting it to the battery and the alternator as well as connecting it to the truck’s electrical system. Wiring should be done according to manufacturer instructions.

Finally, ventilation ducting should be installed in order for the hot air generated by the APU’s engine to be exhausted safely. This should include both intake ducting that brings fresh air into the unit as well as exhaust ducting that carries hot air away from it.

Conclusion:
Installing an APU on a semi truck is not a difficult task but it does require precision and attention to detail.

It involves choosing a model that meets your needs, mounting it securely in place, running wiring between its components and installing ventilation ducting for safe exhaust of hot air from its engine. With careful consideration and accurate installation, an APU can help you save fuel and reduce engine idling time while providing comfortable climate control inside your semi truck cabin.
