Cummins Power Generation has launched a new lean-burn 50 Hz gas generator set product line. This extends the capabilities of the existing QSV91G generator range and allows these generator sets to run on low methane number fuels and produce lower emissions.

The new line marks the debut of a 2.0 Me variant, alongside the improved 1,540 kWe and 1,750 kWe models. Primary applications for the new models include prime, peaking and combined heat and power (CHP), as well as continuous operation in island mode and standby power.

Their load handling attributes and capability of running on pipeline and low methane number fuels down to 43 MN make them suited for remote locations where grid power is unavailable, such as mining, oil or gas fields, or in regions of the world where grid power is either unreliable or inaccessible.

NOx emissions ratings as low as 250 mg/Nm3 are available where required. The range retains its ability to run on biogases from landfill, digester and sewage sites. The new product line is designed to meet the ISO 8528 G1 standard. The compliance means that the new models deliver improved transient performance with quicker recovery to rated voltage and frequency during start-up and as loads fluctuate.

An additional major feature of the new line-up is black start capability – the ability to bring the generator set quickly into operation without relying on an external electricity source such as the grid. Black start capability frees the generator set from grid dependency and allows its deployment anywhere there is a need. The new product line is also capable of running in high altitude and high ambient temperature environments with minimal derating.
