New Power for 2025: The Cummins DQCB 750 kW Diesel Generator
As we move through 2026, the demand for reliable, high-output standby power has never been higher. For industrial facilities, data centers, and healthcare institutions, the margin for error during a power outage is zero. Central States Diesel Generators is proud to highlight one of the most robust additions to our current inventory: the New Cummins DQCB 750 kW Diesel Generator (CSDG# 4302).
This 2025 model year unit represents the pinnacle of modern engineering, combining the legendary reliability of the Cummins brand with the high-performance QSK23 engine series. Whether you are looking for new Cummins generators to anchor a new construction project or need to upgrade an existing facility with new Cummins diesel generators, the DQCB 750 kW offers a perfect balance of footprint, efficiency, and raw power.
The Heart of the Machine: The Cummins QSK23-G7 Engine
At the core of the DQCB 750 kW model is the Cummins QSK23-G7 engine. Cummins has long been a global leader in engine technology, and the QSK23 series is a prime example of why. Rated at 1220 HP at 1800 RPM, this engine is designed to handle the most demanding standby applications.
Technical Performance and Reputation
The QSK23 is an in-line, 6-cylinder, 4-stroke diesel engine known for its compact footprint without sacrificing durability. In the world of diesel engines and generators, the “compact yet powerful” designation is often overused, but the QSK23 earns it through high-pressure injection and advanced combustion modeling.
This engine is EPA Tier 2 certified, making it ideal for stationary standby applications across the United States. With zero hours on the clock, this 2025 model provides the peace of mind that only brand-new equipment can offer. It is engineered for fast starting and can accept a full load in a single step, which is a critical requirement for emergency power systems.

Advanced Features for Modern Facilities
A generator is more than just an engine and an alternator; it is a complete system that must integrate seamlessly with your building’s infrastructure. The DQCB 750 kW unit (CSDG# 4302) comes fully loaded with features that simplify installation and operation.
Level 2 Sound Attenuated Enclosure
In many urban or suburban commercial settings, noise pollution is a significant concern. This unit is housed in a Level 2 sound-attenuated enclosure. This high-grade housing significantly reduces decibel levels during operation, ensuring that your facility remains compliant with local noise ordinances while protecting the unit from the elements.
PowerCommand 2.3 Control System
The PowerCommand 2.3 digital control panel is the “brain” of the generator. It provides total system integration, including automatic remote starting/stopping, precise frequency and voltage regulation, and advanced diagnostic tools. For facility managers, this means easier monitoring and faster troubleshooting, ensuring the generator is always ready when the grid fails.
Long-Duration Fuel Supply
The inclusion of a 1500-gallon sub-base fuel tank is a game-changer for emergency preparedness. Depending on the load, this massive capacity allows for extended runtimes during prolonged outages, reducing the logistical stress of frequent refueling during a crisis.
