Generac sell lots of gas fueled 1800 rpm liquid cooled units. Look at the 22, 27 kw units for exampleNot right exactly. Diesel gensets are 4 pole / 1800 rpm. Gas is 2 pole / 3600 rpm. I own both btw. Gas can be water or air cooled but diesels are almost always water cooled. In fact I don't know of any major producer that uses an air cooled diesel engine.
