NOTICE - East General Lab Wing is Open for Research
by Voorhis, Mark L. 14 Jan '21

14 Jan '21

Dear All, The east wing lab areas are now open for research. The repairs to the HVAC system are complete and lab ambient controls are back to normal. Thank you, Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036 From: Voorhis, Mark L. Sent: Friday, December 18, 2020 6:26 AM To: bnc-facility-notice(a)ecn.purdue.edu Subject: NOTICE - East General Lab Wing HVAC Interruption All, At 5:30AM this morning a building controls alarm was sent to Purdue trades to investigate the shutdown of AHU 2 that service both first floor and second floor east lab wing (layouts below). At this time there is higher negative static pressure in all these labs sucking the door to the lab space close. It may be difficult to open these door when entering these labs. The temperature and humidity control in these labs will be out of control until we can get AHU 2 operational. We will keep you posted by email on any changes .

NOTICE - Failure of the Ultra-Pure Water System and Cleanroom Humidity Control
by Voorhis, Mark L. 13 Jan '21

13 Jan '21

Dear BNC Users, Tonight there has been a critical failure of the building wide Ultra-Pure water system. As a result there is no Ultra-pure water flow or cleanroom humidity control that requires ultra-water to operate. The cleanroom relative humidity levels are at ~14% with a setpoint of 45%. It is unclear when the ultra-pure water system will be operational. We are waiting for a response for technical support from an outside ultra-pure water engineering firm. We are sorry for the unplanned interruption. Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036
