Next generation of high-horsepower generator sets from Cummins

Hydrocarbon Engineering,


Cummins Power Generation Inc., a subsidiary of Cummins Inc., is introducing the QSK95 Series generator sets, a new line of high-performance generator sets.

The QSK95 generator sets are Cummins Power Generation’s most powerful diesel generator sets to date, offering up to 3.5 MW 60 Hz and 3.75 MVA 50 Hz. They are engineered with the highest kilowatt per square foot ratio in their class, resulting in a smaller footprint that achieves a 20% improvement in power density.

Fuel economy

While the new generator sets boast more power, they also offer best-in-class fuel economy – over the course of 8000 hours of operation, the QSK95 can achieve fuel savings of more than US$ 400 000.

Meeting the demand for reliability in harsh conditions and challenging environments

The durable and robust QSK95 Series generator sets are ideally suited for oil and gas operations, mining, or any project where harsh conditions, challenging environments and the demand for reliable, continuous remote power exist. Best-in class fuel economies from an innovative fuel injection system, fewer maintenance requirements, longer service intervals and 25 000 hours to major overhaul make these generator sets ideal for prime power applications.

The QSK95 Series generator sets are also engineered to deliver reliable, mission critical power protection without interruption. The generator sets accept 100% of rated load in a single step, and are ready to accept facility load in less than 10 seconds. With a smaller footprint, the QSK95 Series requires less space to install, and, in multiple-generator set applications, fewer generators are required to achieve the necessary power output – all which result in substantial cost savings.

Features

The QSK95 Series generator sets are available in multiple rating options for specific power generation applications, including: continuous, prime power, mission critical and standby. Cummins also offers a data centre continuous (DCC) rating specifically tailored for data centre requirements. DCC places no limitation on the number of generator set operating hours and pre-approves the QSK95 Series for the Uptime Institute’s Tier III and Tier IV data centre site certifications. Other features include:

  • Reduced operating cost with long maintenance intervals, such as three-year or 1000-hour oil and filter change intervals.
  • Low temperature after-cooling optimises radiator package sizing and contributes to the generator’s smaller footprint.
  • Condition-based maintenance sensors monitor air and fuel filter restrictions and prompt filter changes only when required.
  • Single shaft, dual element cooling pump that minimises potential leaks and failures while improving efficiencies.
  • Positive flow circulating pump in the coolant heater enables even heating throughout the engine block for faster and more reliable starts.
  • Oil cooler that provides access to the thermostat without lifting the engine.
  • Mounting rail design allows the alternator to slide back on the chassis without having to lift it.
  • Larger, accessible engine hand holes facilitate cylinder block access without dropping the oil pan.
  • Global availability of technicians, parts and engineering support.
