  2. Values of 469-715 bhp while meeting EPA Tier 3, IMO II and EU Stage IIIA emission regulations.

 

Why buying it? For the meticulous assistance, which will be by your side wherever you are on board your ship.

Why Choosing It

Cooling system

 

The cooling system features a heat exchanger and cooled keel options for all ratings.

 

Emissions

 

Regarding emissions, the engine complies with IMO II and EU IWW standards for all ratings.

 

Post-refrigeration system with separate circuit

 

One of the unique features of the C18 ACERT engine is the Separate Circuit After-Cooling (SCAC) system, which does not allow sea water to circulate through the aftercooler.

 

Additional nominal values

 

Finally, you can request specific additional ratings that comply with IMO II emissions regulations as well as additional ratings that comply with both EPA Tier 3 and IMO II emissions regulations.
