METSTRADE: Debut for Cummins Marine Onan gensets
Cummins has unveiled two new additions to its Onan marine generator portfolio: the MDC (Marine Diesel Cummins) Turbo and the Onan QSB7E ranges.
The new generator sets are being showcased at METSTRADE 2024 this week. The launch of the MDC Turbo and Onan QSB7E further enhances Cummins’ offering as a single-source provider for marine power solutions. With Cummins as the parent brand of both Onan and Stamford – the global leader in alternators for marine applications – the company says customers can now fulfil all their vessel power needs from one trusted partner.
According to Cummins, this integrated approach simplifies procurement and support, ensuring reliability and performance across the power ecosystem for marine applications.
The Cummins Onan range now covers 4kWe to 195kWe. Previously, the highest Cummins Onan rating available was 65kWe.
The two new ranges, which can run on 100 per cent hydrotreated vegetable oil (HVO 100), build on a proud heritage of reliable, smooth and efficient power delivery.
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.
Cédric Merveillaud, Cummins director of marine Europe, says: “With the one supplier for propulsion and auxiliary power, life becomes a lot simpler and more productive for boat builders and owners. Cummins can handle the entire power demand.”
The MDC genset complies with EPA Tier 3 and EU Stage V regulations and is available for both commercial and recreational marine applications as a 50Hz or 60Hz model.
It can also be specified as either non-aftercooled or aftercooled. This provides two power outputs, giving the genset a rating of 40 to 80kWe and 80 to 110kWe respectively.
Using the Cummins Onan Digital Display, the MDC provides diagnostics including extensive engine and alternator information, ensuring customer ease on the water.
At the top end of the Cummins Onan genset scale now sits the Onan QSB7E, a low noise power solution for a variety of maritime applications including high-end superyachts, small passenger ferries, fishing boats and offshore support vessels.
Available as unclassed, class-ready and full-class, the Onan QSB7E has ten power nodes and can be specified with an open or enclosed unit in both 50 and 60 Hz models. Maximum output is up to 195kWe.
Like the MDC, the Onan QSB7E can be supplied with the additional option of a front-mounted power take-off which can be used to power various auxiliary systems, for example, hydraulic pumps, giving the customer flexibility and redundancy onboard.
The MDC and Onan QSB7E have single-side service access and the water-cooled exhaust can be installed either in forward or rear-facing configuration. At the base of both generators are multiple outlets for fuel and battery cables.
“Cummins marine genset products are designed and built to provide reliability, performance and durability at reduced noise and vibration levels,” adds Merveillaud. “That’s why this complete marine generator set package is ideal for recreational and light commercial vessels.
“The 99kW commercial genset node is very popular in certain markets, and we expect the B4.5 genset package with a Cummins Stamford alternator will be an obvious choice when selecting power for operators for years to come.”
The MDC and Onan QSB7E gensets are backed by Cummins’ warranty (five years / 2,000 hours), and users have access to a worldwide service network of more than 10,000 authorised dealer locations, the largest such network in the world.
