Benefits & Features
Intelligent simplicity
This MaK design principles is most clearly reflected in the reduction of the number of components. About 40 % of parts have been dispended. It has resulted in a market gain in operational and a reduction of operating costs.
Reliable energy supply
The complete diesel generator set is notable for its ease of installation, reliable operation, ease of maintenance and provides good component accessibility.
Ready for installation
In addition to many outstanding technical features, the long-stroke M 25 E engine is also easy to install and provides good maintenance access to all components.
Complete propulsion system
The supply of complete propulsion systems is a market requirement which is becoming increasingly important.
System responsibility and supply from a single source, accurately matched interfaces and coordinated delivery data control
