What is the purpose of the raw water cooling system on the RB-M 45?

The purpose of the raw water cooling system on the RB-M 45 is to cool the engine and other critical components that generate heat during operation. By circulating water from the surrounding environment, the system absorbs excess heat and prevents overheating, ensuring the engine operates efficiently and remains within safe temperature limits. This cooling mechanism is vital for overall performance, longevity, and reliability of the vessel's powertrain.

In contrast to maintaining cabin temperature or managing ballast levels, which are functions handled by different systems, the raw water cooling system directly supports engine performance. Similarly, purifying the freshwater supply does not fall under the functions of this cooling system, as it is focused solely on heat management rather than water treatment.
