5. Example of applications with CoolFlex
When high density IT equipment is used (typically over 10kW per rack) or load distribution in
the row(s) of racks is not constant and high energy efficiency is required it is strongly recom­
mended to apply CoolFlex (cold aisle containment) together with Liebert CRV.
Other advantage of the CoolFlex application is less limitations, see above points.
