Late entry.

The compressor that produces the purge air developed a seeping leak of oil a few weeks ago, second oil leak, located were a previous work was done last March, see here for details, then the leak turned into a drop by drop leak, then other hose joints started to seep, we called the vendor regarding the leaks so they can fix the issue, they should be here next week.  However, due to the amount of oil the unit has lost, we decided to add some oil to the compressor.

Before adding oil, the chambers were checked that all soft covers were on, operator was notified that the compressor was getting shut down, Kobelco unit was turned off.  All doors for the compressor unit were opened, air moving equipment was added to cool down the compressor for about 1 hour, then oil was added until the sight glass showed a good level.  Unit was restored and turned on.  We allowed the unit to run one hour to achieve nominal temperature, then we opened the purge air to the chambers. DP at the drying towers showed -78 degrees C.

Attached are a few photos, the front display shows the oil temp TT4, nominal is above 110 degrees F, and the unit alarms above 170 degrees F.
