▶️Introduktion
How Fresh Water Generators (FWG) Work
Seawater is pumped to the condenser heat exchanger. Some of it passes through the condenser and then passes through the evaporator heat exchanger. Some of it is pumped through an educator/ejector and is discharged overboard. Some of the saltwater is siphoned from the condenser to the ejector in order to maintain a vacuum on the FWG shell.

Hot water is pumped to the evaporator where it heats the seawater. The hot water (often engine jacket water) is then discharged from the evaporator and returned to the hot water main circuit.

The FWG shell is placed under vacuum so that the hot water can boil the seawater at a temperature below 100 degrees Celsius. The seawater evaporates and exits the evaporator as water mist. The water mist passes through a demister and condenses on the condenser. The condensed water is distilled water and is pumped out of the FWG by a small fresh water pump. At this stage, the saltwater has been desalinated and the process of desalination is complete.

the best way to teach smone with smthng is to show the you a lot=) I wish there would be much more of videos like this=)

[pellefantenplaysthepiano]

This was a really great video explaining the functioning of an evaporator in a very thorough way. Thanks a lot!

[tanyalahies]

There is a salt water desalination project at my village and so we do appreciate this kind of machine because we do struggle with fresh water. Thank you.

[sudeshgaonker]

Very nice 3D View presentation. Explained everything in best possible manner. Thanks for sharing valuable videos for free for learning purpose.

[sylvester]

Watching your videos alone made my life easy.

[edwardthabisho]

Thanks I've been looking for someone who can simplify ME like you do.

[jaishetty]

I needed to see the fresh water collection arrangement.

[jermaineomorogbe]

Fantastic resource! Thanks for sharing this!

[vinithkumar]

Thank you..for your brief explaining about fresh water generator. ....

[matthewws]

Quality explanations and visual presentation. Thanks Jon

Hello sir great video! Please do not stop making videos like these. Very interesting.

[harishsinghbisht]

I really love the way you teach sir... Lots of love to you ❤from india 🇮🇳

[wades_world]

Thank you! i learned a lot from this high-quality video :-)

[freakshow]

great video. One small issue: there is no mist formation, only water vapor. The demister is only to catch tiny droplets that result from boiling.

[sailorkashif]

Sir please explain how salinity is check, and how salinometer work...thanks for video

[bimal]

Very informative. 👍👏👏
Please make a video on Oily water separator too which is used onboard.

[akarl]

Best video in youtude regarding FWG. Thank you

[naveedjamal]

Thank you so much sir
I really appreciate your way of teaching its really unbelieveable, how you come up with these 3D models and explain each part

[djhousesmash]

Great job. Nice explanation. Keep up the good work 🤙😊
