Truck Auxiliary Power Units (APUs) are revolutionizing how long-haul drivers manage fuel consumption and comfort. By providing power for cab climate control, appliances, and electronics without running the truck’s main engine, APUs reduce idling time — saving fuel and decreasing engine wear.

Idling a diesel engine for extended periods wastes significant fuel and increases maintenance costs. Studies show that a Class 8 truck idles roughly 1,800 hours per year, consuming thousands of gallons of diesel. APUs can cut idling fuel use by up to 90%, leading to savings of $5,000 to $10,000 annually per truck, depending on fuel prices and usage.

There are two main types of APUs: diesel-powered and battery-powered. Diesel APUs are reliable and provide continuous power, while battery APUs offer quieter operation with zero emissions, ideal for urban areas with strict anti-idling laws.

Installing an APU requires considering truck compatibility, electrical system integration, and space for mounting. Professional installation ensures maximum efficiency and warranty compliance.

Beyond fuel savings, APUs improve driver comfort by enabling air conditioning and heating while parked, leading to better rest and increased safety on the road. They also help fleets comply with increasingly common anti-idling regulations, avoiding costly fines.
