Liebert ICOM
The Liebert iCOM control system featured on Liebert Precision
Cooling products brings high-level supervision to multiple
units, allowing up to 32 cooling units to work together as a
single system to optimize room performance. Liebert iCOM
controls offer a variety of advantages, including increased
system energy efficiency, availability and flexibility.
Control:
Controls cooling and humidity to optimize
environment – provides dew point control for
cooling efficiency.
Manages data center “zones” to optimize cooling
– establish zones for non-homogeneous heat loads,
contained areas, and localized high density areas.
Ensures continuous operation with auto-
changeover to standby unit in case of primary
unit shutdown – no additional equipment is
required for lead/lag units.
