Large gensets.

Reciprocating gas engine gensets for on-site and prime power, often 1 to 20 MW a unit, and often run as a group of several units.

If you're selling, have ready

  • Make, model and serial numbers of the engine and generator
  • Year in service
  • Running hours, and hours since the last major overhaul
  • Maintenance records and oil analysis
  • Emissions controls fitted, and the last emissions test
  • The fuel it runs on, and the gas pressure it needs
  • Frequency and voltage: 60 Hz or 50 Hz
  • What's included: switchgear, controls, cooling, enclosure
  • Removal: who, how fast, any site deadline

If you're buying, ask

  • Hours since the last major overhaul, and when the next one is due
  • Emissions controls fitted, and what your permit allows
  • The gas quality and supply pressure it needs
  • 60 Hz or 50 Hz: a genset built for one frequency is rarely converted to the other
  • How many units are available, and whether they run in parallel
  • How it was preserved after shutdown
  • Who pays for removal and shipping

Why existing units matter

New large gas engines are often ordered as a fleet, and delivery can take a year or more.

Gensets from a closed site or a finished project are already built and have a service history. They still need their records, an independent inspection and a plan to move them. We bring the records to the buyer and keep each step moving.

Have gensets you aren't running, or need some?
