Controlling gaseous and particulate contamination in data centers. 2.

Summary

Data centers operating in areas with elevated levels of ambient pollution have begun to experience hardware failures due to changes in electronic equipment mandated by a number of "lead-free" regulations that affected the manufacturing of electronics, including IT and datacom equipment. Implementation of these regulations have resulted in an increased sensitivity of printed circuit boards, surface mounted components, hard disk drives, computer workstations, servers, and other devices to gaseous contaminants. As a result, there is an increasing requirement for air quality monitoring in data centers. This is especially true for corrosive airborne contaminants. When monitoring indicates that data center air quality does not fall within specified corrosion limits, and other environmental factors have been ruled out (i.e. temperature, humidity, etc,), gas-phase air filtration is recommended. This would include air being introduced into the data center from the outside for ventilation and/or pressurization as well as all of the air being recirculated within the data center. The optimized control of particulate contamination should also be incorporated into the overall air handling system design. See also this issue of the Bulletin, reference 2010-1621.
