Hello All,
I am in the process of doing some PID tuning on the level controllers for our refrigeration system.
I am trying to tune the Level controllers for the Economizer and Shell/Tube Chillers. The level controllers are all upstream on the vessels. The Economizer feeds 3 Chillers that...

Process temp. control would be controlled by the chiller pressure. A back pressure control valve is utilized to keep desired pressure on the chiller and control process outlet temps.
Thank you for the response RicoB.
Emmanuel Nailed it with the first answer. Insufficient space in the Chiller will result in droplets/mist being carried out of the Tube/Shell into the suction header.
I have also been told that leaving some tubes exposed can increase efficiency and save horsepower on compressors? Can...
