Cummins Onan QD 12000 Diesel Commercial Mobile Generator - 12.0HDKCD-2209

The Cummins 12HDKCD-2209 QD is a 12,000-watt diesel-powered generator designed to meet the power needs of the most demanding commercial mobile applications. Built for service trucks, emergency response units, mobile workshops, and specialty vehicles, this generator offers high-capacity output, exceptional durability, and fuel efficiency for continuous operation in challenging environments.

Powered by a reliable Kubota D1703-M-E3B 3-cylinder diesel engine, the generator delivers consistent performance with a 4-cycle, liquid-cooled design that’s engineered for extended runtime and heavy-duty usage. The unit produces 120/240V single-phase power with pure sine wave output, ensuring clean, stable power delivery suitable for sensitive electronics, industrial tools, and high-demand equipment.

Designed with Cummins’ Quiet Diesel™ technology, the 12HDKCD-2209 QD operates at a sound level of only 68 dB(A) at 10 feet under full load, making it one of the quietest generators in its class. Its fully enclosed muffler and sound-insulated housing minimize vibrations, ensuring smooth and quiet operation even in urban or noise-sensitive environments.

Fuel efficiency is a core feature, with consumption rates of 0.5 gallons per hour at half load and 1.2 gallons per hour at full load, making it ideal for businesses that require prolonged use without frequent refueling. Additionally, it features a fuel filter/water separator for enhanced fuel quality and engine protection.

Weighing 816 lbs (370 kg), the generator’s compact and rugged design allows for easy installation across various vehicle configurations. It includes a remote start/stop capability, providing operators with convenient control from inside the vehicle or workspace.

Safety features are thoughtfully integrated, including overload protection, low oil pressure shutdown, high-temperature shutdown, and over-speed regulation to ensure safe and reliable operation under various load conditions. A built-in self-diagnostic system provides real-time alerts for simplified maintenance and troubleshooting.
