When your business needs serious backup power, you don’t want to mess around with second-rate equipment. The Cummins DQKAN diesel generator represents the gold standard in industrial power generation, delivering an impressive 2500 kW of standby power that keeps critical operations running when the grid fails. At Central States Diesel Generators, we’re proud to have these powerhouse units in stock and ready to ship to businesses across the country.
Why Cummins Sets the Standard for Industrial Generators
Cummins has been synonymous with reliable diesel power for over a century, and there’s a good reason why Fortune 500 companies, hospitals, data centers, and manufacturing facilities trust their most critical operations to Cummins generators. The brand’s reputation isn’t built on marketing hype: it’s earned through decades of engineering excellence and real-world performance under the toughest conditions.
What sets Cummins apart is their vertical integration approach. They design and manufacture both the engine and the generator components in-house, ensuring perfect compatibility and optimized performance. This means fewer compatibility issues, better fuel efficiency, and longer equipment life. When you’re looking at a generator investment that could serve your facility for 20+ years, that kind of engineering matters.
The DQKAN model specifically represents Cummins’ commitment to meeting modern environmental standards without sacrificing performance. With full EPA Tier 2 compliance, this generator delivers clean, reliable power while meeting strict emissions requirements that many older generators simply can’t match.
Technical Specifications That Deliver Results
Let’s get into the numbers that matter. The Cummins DQKAN packs serious power with its 2500 kW standby capacity (2250 kW prime power), making it ideal for large facilities that can’t afford downtime. At the heart of this beast is the QSK60-G19 NR2 engine: a V16 configuration that produces 3,640 horsepower at 1,800 RPM.
Key Performance Stats:
- Power Output: 2500 kW standby, 2250 kW prime
- Voltage: 277/480V, 3-phase, 60Hz
- Engine: QSK60-G19 NR2 with 60.2L displacement
- Fuel System: Modular common rail for optimal efficiency
- Sound Level: 75 dBA at 23 feet (sound attenuated)
- Emissions: EPA Tier 2 compliant
The precision engineering shows in the performance specs too. You get ±0.5% voltage regulation from no load to full load, which means your sensitive equipment gets consistent, clean power regardless of demand fluctuations. The isochronous frequency regulation with ±0.25% random variation keeps everything running smoothly, from HVAC systems to computer servers.
Fuel Capacity Built for Extended Runtime
One of the standout features of the DQKAN is its substantial fuel storage capacity. These units come with either 3,750-gallon or 3,960-gallon UL-142 sub-base fuel tanks with secondary containment. That translates to approximately 24 hours of continuous operation at full load: enough to ride out most power outages without refueling.
The fuel system isn’t just about capacity though. The modular common rail design optimizes combustion efficiency, which means you get more runtime per gallon and reduced operating costs over the generator’s lifetime. For businesses running on tight margins, those fuel savings can add up significantly over the years.
Advanced Control Systems for Peace of Mind
The DQKAN comes equipped with Cummins’ PowerCommand 3.3 digital control panel, which puts comprehensive monitoring and control at your fingertips. This isn’t your grandfather’s generator control panel: it’s a sophisticated system that can parallel multiple generators, provide remote monitoring capabilities, and integrate with building management systems.
The package also includes essential components like the AmpSentry UL listed protective relay, alternator heater for cold weather starts, and EnerGenius 10-amp battery charger to ensure reliable startup when you need it most. These might seem like small details, but they’re the difference between a generator that starts reliably every time and one that leaves you in the dark when you need it most.
Applications Where the DQKAN Excels
With 2500 kW of capacity, the DQKAN is designed for substantial power demands. We typically see these units installed at:
Manufacturing Facilities: Keeping production lines running during outages prevents costly downtime and maintains delivery schedules. The DQKAN’s quick startup and stable power output make it ideal for facilities with sensitive equipment or processes that can’t tolerate power interruptions.
Data Centers: Server farms and data centers require uninterrupted power to maintain uptime guarantees. The DQKAN’s precise voltage and frequency regulation ensure servers and networking equipment receive the clean power they need.
Healthcare Systems: Hospitals and medical facilities can’t afford power failures that could impact patient care. The extended runtime capability and reliable startup make the DQKAN a trusted choice for critical healthcare infrastructure.
Commercial Buildings: Large office complexes, shopping centers, and mixed-use developments benefit from the DQKAN’s capacity to handle substantial electrical loads while meeting noise regulations with its sound-attenuated enclosure.
Installation Considerations and Physical Specs
Before you fall in love with the performance specs, let’s talk about the practical side. The DQKAN is a substantial piece of equipment, measuring 144 inches wide by 570 inches long by 168 inches high, with a total weight of 72,175 pounds. Add the separate fuel tank at 10,850 pounds, and you’re looking at serious installation requirements.
But here’s the thing: that size reflects the robust construction and components needed to deliver reliable 2500 kW power output for decades. The sound-attenuated enclosure keeps noise levels to just 75 dBA at 23 feet, making it suitable for installations where noise is a concern. That’s quieter than many smaller generators without sound attenuation.
We provide complete installation support, including site surveys, engineering services, and delivery coordination. Our team understands the logistical challenges of installing large generators and works with customers to ensure smooth project execution from delivery to commissioning.
