Cummins has extended its portfolio of Onan marine generator sets with the introduction of the MDC (Marine Diesel Cummins) Turbo and Onan QSB7E ranges.
Details of the two generator sets were shared at the Marine Equipment Trade Show (METS), a premium European showcase for professionals in the leisure marine industry.
The arrival of the MDC Turbo and Onan QSB7E means boatbuilders and owners can now deal with a single trusted brand – Cummins – for the entire power requirement of their vessel. Cummins is the parent brand of Onan and of Stamford, the leading name in alternators for marine applications.
Cummins generator sets are renowned for their robust build quality and outstanding performance characteristics, notably in the area of low noise, vibration and harshness (NVH). The two new ranges, which can run on 100% hydrotreated vegetable oil (HVO 100), build on that proud heritage of reliable, smooth and efficient power delivery.
The versatility of the MDC and Onan QSB7E is enhanced by the ability to synchronise the generator sets, yielding benefits such as improved stability of electrical supply, greater fuel efficiency and higher levels of comfort all round for passengers and crew.
