Marine crews, engineers, and operators rely on powerful, reliable generators to keep essential systems running onboard vessels. The Cummins QSL9-DM Marine Generator Set delivers robust performance with a power output of 264 kW, capable of meeting the specific electrical load demands of each ship. This diesel-powered generator utilizes MGO fuel and features a six-cylinder, inline engine configuration with a displacement of 8.9 liters. It operates at 1500 RPM, generating a 50 Hz frequency, making it suitable for a wide range of marine applications. To ensure optimal performance and longevity, Cummins recommends scheduled oil changes, filter replacements, and valve train servicing according to their service manual. Periodic load-bank testing is also advisable for standby or lightly loaded units.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
