New | M 20 C Marine Generator Set

The main features of the diesel generator set M 20 C are ease of installation, reliable operation, ease of maintenance and easy component accessibility. Its base is the rigid frame which forms a foundation for both the engine and the generator set and includes an integral, large-capacity oil sump and universal fuel supply equipment covering both HFO and MDO operation. The M 20C has a wide range of application providing power for the continuous generation of electricity where a high level of reliability is important. The power range of the M20C engine series as a generator unit varies from 1,224 to 2,160 kVA.

The M 20 C Is An Engine With A High Safety Level. This Applies Not Only To Those Special Internal Design Features Which Guarantee Long Component Life And High Availability But Also To Safety In The Area Around The Engine. As A Result, Solas Regulations Are Strictly And Consistently Observed. Explosion Protection Cover For The Cylinder/crankcase Housing And Cladding Of The Complete Fuel And Exhaust Gas System In Stainless Steel Are Part Of An Overall Solas Safety Concept.

Long Maintenance Intervals And The Life Of Components Are The Basis For Low Operating Costs.

The Engine Is Marketed With A Standardized Range Of Installed Pumps And Filters. Interfaces For Fuel, Lubricating Oil And Cooling Water Systems Are Located At The Opposite End Of The Crankshaft Coupling For Ease Of Connection.

The Complete Diesel Generating Set Is Notable For Its Ease Of Installation, Reliable Operation, Ease Of Maintenance And Good Component Accessibility. The Basis Is Formed By The Rigid Base Frame As Foundation Of The Engine And Alternator With Integrated Oil Sump, Large Oil Volume And Universal Equipment For Both Hfo And Mdo Operation.

System Responsibility And Supply From A Single Source, Accurately Matched Interfaces, Coordinated Delivery Data Control.
