Hello Amir,

Do you have cooled water temperature monitoring and non condensable temperature? Look for big difference between those temperature each street since air leakage will decrease non condensible temperature even more than usual. As a rule of thumb, gap should be around 5 C. After locating the street in trouble, shutdown the fan and monitor with an IR camera how the cold area stars increasing, if there are one. It could help you to find the leakage.

Best,
Manuel

I have a question regarding air pockets. I have frequently seen cooled areas with IR camera on bundles. Sometimes I stopped the fan in order to know whether this is air leakega or air pocket. After seconds the fan is stopped, the cooled area disappear, but when the fan is re-started, this cooled area appear again!
Do you have any similar problem? Oxigen is not high in the cycle.
