Hello folks.
I have some problems with two of my screws. They are in the end of each lineup. Sometimes, I have not been able to find any regularity, they stop from high oiltemperature. They have oilcoolers with NH3. The temperature is jumping, sometimes to get so high the compressors stops.
There is no oil in the liquidline nearby the oilcooler. There is no air in the system.
Anybody here seen the same? And most important: Anybody here have a suggestion what to do about it?
If you need additional information about my plant, please say so.
