ELECTRIC APU — QUICK VERSION

Cleaner, quieter power while parked.

An electric APU runs the sleeper A/C, heat and electrical loads without idling the truck.

Instead of a small diesel engine, it uses lithium batteries that recharge while you drive.

More Information

LESS IDLING

Stop burning fuel to sit still.

Less idling means less fuel, fewer engine hours, and less stress on the DPF and aftertreatment system.

ONE BATTERY BANK. TWO JOBS.

No extra battery box.
No frame-rail APU engine.

The same Polar Fox lithium batteries replace the factory starting batteries, start the truck, and run the APU.

400AhDual-purpose lithiumMinimal net added weight

Each Skana battery weighs about 30 lb, so replacing conventional starting batteries offsets much of the weight added by the A/C system.
