Air Mixing Lowers Delta-T• Cooling efficiency suffers
• Capacity unnecessarily limited

Containment Stops Mixing• Cooling efficiency surges
• Capacity expands

What is Containment?Placing isolation barriers at the front, back,
and top of the aisles to eliminate cold air
loss and to stop hot air from penetrating
into the cold aisle.
The reduction in air mixing increases the
return air temperature to the CRAC units,
raising the delta-T across them which raising the delta-T across them which
results in more efficient cooling. The
isolation also eliminates hot spots and
makes the supply air temperature more
uniform across the server inlets. This
increases reliability while allowing the
supply air set points to be safely increased.

Compelling ROI• Payback typically less than a year
• Immediately turn off CRAC units
• Variable speed fans run slower
• Reduce heat related failures
• Eliminate unnecessary • Eliminate unnecessary re-humidification
• Increase CRAC set points
• Increase chilled water set points
• Increase the amount of economizer usage time
• Extend the data center’s life
