I ran the dry air system thru its quarterly test, FAMIS task.  The system was started around 8:20 am local time, and turned off by 11:15 am.  System achieved a dew point of -50 ^oF, see attached photo taken towards the end of the test.  Noted that we may be running low on oil at the Kobelco compressor, checking with vendor on this.  Picture of oil level is while system is off.
