Subject: [Esr-users] ESR Second Stage compressors – 31 July 2020


Hello ESR Users,


ESR Second Stage Main Compressor C2 has a problem with the discharge temperature switch, which is a protective feature. Since C2 much be shutdown, C3 will be temporarily placed online as a second stage compressor. Another nuisance issue with C2 will be checked. The work is scheduled to start at 0800 in 31 July 2020. Completion is anticipated during the same dayshift.  Ideally, the work should be invisible to ESR Users, especially with no 15K targets online.


Thanks
