All BNC Users:

Purdue Utilities Distribution has an issue with a broken steam valve that services Discovery Park.  A steam shut down is scheduled for 3 hours this coming Tuesday (May 19) from 6:00 to 9:00 AM to replace the valve. 

The main impact will be seen in all laboratory areas where the temperatures are expected to be 10° to 12° colder than normal.  The reason for this sharp change in temperature is the laboratory areas incorporate a single-pass airflow system that doesn’t allow us to capture any of the exhausted heat.  Please plan your activities (and clothing) with this in mind.

With this short period of down time I do not anticipate major temperature changes in office or cleanroom spaces since they incorporate recirculation air handling units.  However, operations that are sensitive to small temperature changes, such as critical lithography steps, should not be scheduled during the shutdown period.

Thank you for your cooperation during this short notice shutdown.
