Dell 12th Generation PowerEdge Servers now empower you with more choices regarding cooling infrastructure that allow you to achieve significant operational savings per megawatt (MW) per year. Dell servers, storage units or network switches with Fresh Air capability give you greater flexibility in regulating the operating temperature in data centers, a best practice that can help increase energy efficiency and decrease operational costs by eliminating the need for chillers.
What is Fresh Air Cooling? “Fresh Air” Cooling is an industry initiative to cool the data center by bringing outside air directly inside.
To take advantage of this initiative, the latest 12G Dell Power Edge Servers have been developed for operation at temperature ranges from -23⁰F (5⁰C) to 113⁰F (45⁰C) and humidity from 5% to 90%. Dell Servers with Fresh Air technology can tolerate up to 900 hours of 104°F (40°C) operation per year and up to 90 hours at 113°F (45°C).
When a system is in “Fresh Air” environment, it is expected that there will be times at which the system may be operating above the normal ambient operating range. Systems and configurations that support this mode of operation are known as “Fresh Air Compliant”.
On 12th Generation servers, Dell makes it easy to do the following:
a) warning range (area above the yellow line)
b) critical range (area above by the red line)
