VETUS Waterlock NLPHD test (English Subtitles) for heat resistance at unusually high temperatures.

In this test, we will check whether the new NLP50HD is truly heat resistant. Normally a waterlock is cooled by water, but if the waterflow is restricted the temperature of the waterlock can rise quickly.
All VETUS marine diesels are equipped with an exhaust temperature alarm, which will warn you before temperatures rise to high.
Our normal waterlock materials are well proven in the last decades. For extreme conditions, such as lifeboats, patrol boats or first responders who have to push on, we developed the Navidurin material.

Hi! Why did you run it backwards? Out was connected to engine and inlet to hose?

[@roberttruszkowski4633]

I'm wondering why the test was run backwards on inlet & outlet ports? It's really making me contemplate how good the water lock is actually working! It's showing water then exhaust running in a direction where the whole objective of this design is defeated!.. Confused

It’s backwards. Strange
