Idling laws are always changing. Therefore, it is important to stay informed and keep your APU up to date. Current law requires 10 hours of rest to every 11 hours of driving. During that down time drivers often leave their trucks idling, which can easily cause unnecessary costs due to wasting fuel and wear and tear on the engine. To combat these extra costs many drivers rely on an APU, which allows them to turn off their engine during driving time, but still enjoy comforts like heat, air conditioning, cooking, surfing the web, and watching television. An Auxiliary Power Unit is designed to conserve resources, saving drivers money and helping to maintain the life of your engine.

APU Center is your source for all your Comfort & Auxiliary Power needs!
