Wärtsilä generating sets - W20
Describe project
Wärtsilä generating sets - Tailored to optimize performance
A wide range of generating sets, comprising generator and engine mounted on a common baseframe, are available for both service power generation and for diesel-electric propulsion.
Most Wärtsilä generating sets are designed for operating on standard marine fuel oils. Dual-fuel gensets are flexible when it comes to both gaseous and liquid fuels. The generating sets are resiliently mounted and the generator voltage can be selected. Larger diesel generators are delivered for separate mounting of the diesel engine and generator.
