Dear Birck Users, As of this morning the campus chilled water issue has been resolved and our building is receiving normal cooling water, so the Birck air conditioning and humidity are back to normal. The one exception is for the west lab wing....Air Handler #1 has a leak in the water pump so AH1 is down for repair. The pump seals are being rebuilt, but until the system is repaired and brought back online the humidity and temperature control in the west lab wing will fluctuate. Ron, 7:45 am Tuesday From: BNC-all <bnc-all-bounces@ecn.purdue.edu> On Behalf Of Reger, Ronald K Sent: Monday, June 13, 2022 3:29 PM To: bnc-all@ecn.purdue.edu Subject: [BNC-all] Early Warning of Campus Chiller Issue Dear Birck Users, Wade Power Plant has lost two of four chillers so at this point chilled water to Birck is compromised. Humidity control and equipment cooling water will be affected which could lead to future process issues and equipment cooling issues. The physical facilities organization is aware and they're monitoring the situation. Please be aware that if this condition is not corrected by tomorrow we will be forced to shut down air handling systems which will take equipment and processes offline. (In order of priority, air handlers to the atriums and offices will be shed first in order to maintain temperature and humidity control in the labs and cleanroom. If it progresses from there we will take the tour aisle down, keeping the cleanroom stable as long as possible.) Our building personnel will continue to monitor this situation and keep us informed.
