Row Based Cooling Solutions
Emerson Network Power Liebert CRV Row-Based Cooling Solution
Liebert CRV Row-Based Cooling Solutions are
self-contained precision cooling systems that install within a row
of data center racks—close to the server heat source—for the most
efficient cooling of critical IT equipment.
The rack-sized Liebert CRV provides high
capacity cooling in a small footprint and features the Liebert iCOM
Control System that modulates unit performance in real-time, based
on conditions in the row. Monitoring up to 10 racks with 20 sensors,
the Liebert CRV precisely controls air temperature, humidity and
filtration in the surrounding racks.
-
Variable EC Fans regulate airflow and reduce the fan input
power; resulting in up to 50% less power used by the fans compared
to traditional perimeter cooling.
- High
Performance Air Filters are easily
accessed through the back of the unit.
- Digital
Scroll Compressor enables the
variable cooling capacity to precisely match changing cooling demand
without cycling on and off, reducing energy consumption and
extending compressor life.
- Liebert
iCOM® Control presents up
to 11 temperature measurements and unit performance in an easy to
understand graphical summary.
- 2T Rack
Sensors provide two temperature readings per
rack to ensure the proper amount of cold air is provided to
eliminate hot spots.
- Adjustable
Baffles direct airflow right, left or both
directions, allowing you to easily change the airflow distribution
as your cooling needs change.
- Blue-tinted
hydrophilic cooling coil disburses
water quickly, preventing carryover of water into the cold aisle.
- R-410A
Refrigerant is
environmentally friendly and meets the latest government standards.
- Liebert
IntelliSlot™ Communication Cards can be
accessed without entering the high voltage panel and allow the
system to communicate with remote infrastructure management systems.
Liebert iCOM Controls: Optimized Performance, Reliability, and Efficiency
The Liebert iCOM control system
provides advanced control and monitoring capabilities to Liebert CRV
units, allowing up to 32 cooling units to work together as a single
system to optimize room performance and improve energy efficiency.
Liebert iCOM controls offer a variety of advantages, including
icon-based navigation, adjustable control algorithms, and data
center monitoring capabilities.
Control
- Advanced control algorithms allow the airflow and cooling to be
modulated independently, eliminating excessive operations.
- Temperature sensors attached to server racks allow the
optimal amount of air and cooling to be provided without any
increased risk for hot spots.
- Multiple Liebert CRV units communicate with each other to optimize system performance while reducing noise and airflow, to
provide a work-friendly environment.
- Six control modes of operation allow the Liebert CRV to be
customized for any application.
Monitoring
- Six selectable status screens allow you to customize how system information is presented.
- Up to 20 rack temperatures may be summarized using bar
graphs or a drawing of the data center on the local display, or all
data may be reported remotely, providing users with a built-in
mini-monitoring system.
- All unit information may be reported
remotely through a variety of protocols, including HTTP, SNMP, and RS-485
Modbus.
Predictive Wellness/Maintenance
- Enhances reliability with predictive
analysis of components and performance – advance notice allows proactive
management of system maintenance.
- Event logs store the last 400
messages to enrich
unit history and enhance support.
Service and Spare Parts History
- On-board service history allows prompt access to records for
service personnel.
- On-board spare parts list
provides convenient identification
of the appropriate unit spare parts and part numbers for faster
service and support.
