When dependable power is essential, equipment selection matters. Central States Diesel Generators is offering a low-hour used Cummins diesel generator with a 1000 kW standby rating, a heavy-duty QST30-G5 NR2 engine, integrated fuel storage, sound attenuation, and controls designed for demanding industrial power applications.

The Cummins DQFAD QST30-G5 NR2 generator, CSDG# 5210, has only 383 hours and was manufactured in 2017. It is available for $229,900, located in Waukesha, Wisconsin, and offered FOB Waukesha, WI.

Central States Diesel Generators owns its advertised inventory. This generator is part of our real-time inventory and is available for purchase and shipment. We also have other similar units in stock and ready to ship, including additional QST30-powered generators and DQFAD packages.

Why Cummins remains a leading industrial generator brand

Cummins has built a global reputation for dependable engines, engineered power-generation systems, and extensive service support. Its equipment is used in commercial facilities, healthcare, data centers, manufacturing plants, mining operations, infrastructure projects, and other applications where a loss of power can create serious operational and financial consequences.

One advantage of the Cummins brand is the depth of its worldwide support network. Facility owners and maintenance teams typically value access to established parts channels, trained technicians, technical documentation, and long-term familiarity with Cummins platforms. That support infrastructure is especially important for a large industrial generator that may serve as a facility’s primary emergency power source.

Cummins also designs complete power-generation systems rather than focusing only on the engine. Depending on the package, the generator, controls, excitation system, cooling system, enclosure, and fuel-storage components can be engineered to work together as a coordinated solution.

The DQFAD package reflects that approach. It combines a high-output Cummins engine with a Cummins generator, PowerCommand controls, high-ambient cooling, and a substantial sub-base fuel tank.

The QST30-G5 NR2: a proven V12 industrial diesel engine

At the center of CSDG# 5210 is the Cummins QST30-G5 NR2, a large-displacement industrial diesel engine designed for high-output power-generation duty.

The QST30 is a V12 engine with 30.5 liters of displacement. It is a four-cycle diesel with turbocharging and aftercooling, giving it the airflow and combustion capacity required to produce substantial power at a constant 1800 RPM operating speed.

The engine is rated at:

  • 1490 HP at 1800 RPM
  • 30.5-liter displacement
  • V12 configuration
  • Four-cycle industrial diesel design
  • Turbocharged and aftercooled operation
  • EPA Tier 2 emissions configuration

This combination gives the QST30-G5 NR2 the characteristics buyers typically seek in an industrial backup power engine: substantial reserve capacity, durable construction, and the ability to respond to significant load changes.

The engine’s rugged cast-iron construction is suited to demanding duty cycles. Its large displacement and V12 configuration provide the mechanical foundation for the DQFAD package’s 1000 kW standby output. In facilities with large motors, mechanical systems, pumps, compressors, or other transient loads, the engine’s power reserve can help support fast and stable load acceptance when properly integrated and commissioned.

1000 kW standby power for mission-critical facilities

The DQFAD package is rated for:

  • 1000 kW standby power
  • 900 kW prime power
  • Three-phase, 60 Hz operation
  • 277/480 volts
  • Four-wire, non-reconnectable configuration
  • 2000 amp, 100% rated main-line circuit breaker

The 1000 kW standby rating is the highest standby rating in the QST30 range, making this package a strong candidate for facilities that need substantial emergency power from a single generator set.

Potential applications include:

  • Data centers and technology facilities
  • Hospitals and healthcare campuses
  • Large manufacturing plants
  • Commercial and industrial buildings
  • Distribution and logistics centers
  • Mining and processing operations
  • Airports and transportation facilities
  • Large construction or temporary power projects

The correct generator size depends on the facility’s connected load, motor-starting requirements, voltage, code requirements, operating profile, and future expansion plans. A 1000 kW generator may be installed as a standalone standby source or incorporated into a larger plant with multiple generator sets. The PowerCommand 3.3 digital control panel is paralleling-capable, which can support system designs requiring coordinated operation with compatible equipment.

Low hours and a complete industrial package

One of the most notable features of CSDG# 5210 is its operating history. This 2017 used diesel generator has only 383 hours.

Low hours can be a significant advantage for buyers seeking the value of pre-owned equipment without purchasing a heavily used unit. Instead of waiting for a new factory package or paying new-equipment pricing, a buyer can evaluate a low-hour, large-capacity generator that is already built, configured, and available for shipment.

The package also includes several features that can reduce the amount of additional equipment required for deployment:

Level 2 sound-attenuated enclosure

The generator is housed in a Level 2 sound-attenuated enclosure. This helps reduce operating noise and provides protection for the generator set in an outdoor or semi-outdoor installation, subject to proper site planning, ventilation, exhaust, foundation, and local requirements.

2200-gallon UL 142 sub-base fuel tank

A 2200-gallon UL 142 sub-base fuel tank is integrated with the package. The tank includes secondary containment, providing additional spill-control protection compared with a basic single-wall arrangement.

Fuel capacity and expected runtime will vary according to load, fuel consumption, site conditions, and operating requirements. Buyers should confirm runtime calculations with their engineering and fuel-system teams.

High-ambient cooling

The engine cooling radiator is rated for a 50°C/122°F ambient temperature. This high-ambient rating can be valuable for facilities that operate in hot climates or locations where generator-room and outdoor temperatures rise significantly. Final installation design still needs to account for airflow, radiator discharge, clearance, altitude, and site-specific conditions.

PMG alternator

The package includes a PMG permanent magnet generator. PMG excitation can support generator voltage regulation and excitation performance during demanding load events, depending on the overall alternator and control configuration.

PowerCommand 3.3 controls

The generator is equipped with a PowerCommand 3.3 paralleling digital control panel. This control platform provides digital monitoring and generator-set management functions while allowing the package to be considered for paralleling applications when matched with appropriate switchgear and system controls.

The package also includes a Sens 10-amp battery charger rated for 120/208/240 volts and dual coolant heaters rated for 208/240/480 volts.

Please note: Batteries are not included with this generator. Buyers should account for battery selection and installation as part of their commissioning plan.
