M 20 C M 20 C   Non-Current Overview Specifications Benefits & Features Equipment Related Products View 360 Overview 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. To watch these videos, you will need to accept the use of targeting cookies.
