📦 Product Description

For chief engineers and technical superintendents, the Cummins NTA855-DM is designed to deliver 24/7 stable power with straightforward maintenance access. Its 6-cylinder inline layout, 14-liter engine, JWAC cooling system, and PT fuel injection are engineered for reliability and easy in-engine-room servicing, even in constrained spaces.

Built for continuous-duty marine generator sets, it provides 287 kW (385 HP) of stable auxiliary power at 1800 RPM while meeting IMO Tier I emission standards, enabling global compliance without performance compromise — ideal for cargo ships, tugs, and offshore supply vessels.
