CAT Generators

Caterpillar 3500 series engines set the standard for landfill gas. Other prime movers have tried, but when you take a look at the total cost of ownership, other prime movers do not come close. The total cost of ownership includes fuel gas boosters, siloxane tolerance, fuel pressure, parts availability and field support.
