I don't see how it will even be possible to find an air cooled unit to "replace" to replace something along the lines of 100 Kw. The largest air cooled unit I've seen is a 16 Kw Generac - and that's pushing it for an air cooled.

I haven't heard anything about any new EPA requirements for air-cooled gensets, so I really can't comment... other than to say the EPA won't be happy unit we're using candlelight and riding bicycles.

Can you provide a link about this?
