What is used for cooling the vacuum section? That’s what I want to know ? Also, what temperature should it be maintained at after vacuum cooling? ? If anyone knows, please let me know. Thanks a lot!~~~~~~~~~

We also have the vacuum flash evaporation process; originally, circulating water was used for cooling, but the results were not satisfactory, so we are now modifying the process. Preparing to use lithium bromide for cooling. The temperature requirement is around 20 degrees. The circulating water can only reach around 30 degrees

May I ask whose technology is used for lithium bromide cooling? Thank you

Direct cooling with circulating water is no problem. Is there a problem with your system?
