Auxiliary Power Unit (APU)

Onboard Power on Demand: How APUs Keep Armored Vehicles Running

Military vehicles rely on a constant energy source to operate critical systems even when the main engine is off. Auxiliary Power Units (APUs) fill this role, providing electrical power and climate control without needing the engine to run.

Unlike generators, APUs integrate seamlessly into the vehicle’s design. They don’t require bulky batteries or separate fuel tanks, offering a spacesaving solution. With customizable power outputs ranging from 2 kW to 100 kW, APUs can cater to the specific needs of each vehicle.

Benefits Beyond Engine Life

Description

APU technology offers several advantages:

  • Silent Operation: APUs run quietly, minimizing the vehicle’s noise signature for discreet operations.
  • Fuel Efficiency: By taking over tasks from the main engine, APUs conserve fuel and extend engine life.
  • Continuous Power: Critical systems like weapon systems, communication equipment, and climate control can function uninterrupted, even during engine maintenance or refueling.

Smart Features for Easy Control

APUs come equipped with user-friendly IP7 control units. These digital interfaces display vital information like temperature, fuel level, and battery voltage, allowing operators to monitor system health in real-time. Additionally, the control unit offers both automatic and manual starting options for added flexibility.

In essence, APUs are intelligent systems that ensure military vehicles remain operational and mission-ready, even with the main engine off.
