For sale is a Katolight 125 kW 120/208 Natural Gas Generator. It has a Cummins G-743 natural gas engine. This generator was installed indoors in a foofy "management consulting" company building. Those guys wear expensive suits and used to get paid big bucks, so they, in turn, hired a very expensive maintenance company Cummins NPower, that maintained this generator to be in top shape. The generator has only 500 hours on it. It also comes with an external radiator, that you would install outdoors. The generator is meant to run indoors, that's why the radiator is a separate unit.
I purchased it before the building was demolished and I did see it run. Right now I have no natural gas supply and it is not running. It was carefully removed.

Shipping would not be trivial and you would have to pay for freight shipping. I can load it on a LOW flatbed trailer, like the one you would tow behind a pick up truck. We can also deliver for a fee.
