All, The chiller repairs were completed one day ahead of schedule and the unit is operational again. Fortunately, the humidity deviation from set point was less severe than anticipated due to the unusually cool weather. Temperature and humidity values for the laboratories, cleanroom, and biocleanroom should be back to normal within the next two hours. Thanks again to everyone for their understanding and cooperation during this critical equipment repair. Regards, Jeff Kuhn Facility Engineer Birck Nanotechnology Center Purdue University 1205 W.
