Liebert CRV Row-Based CoolingIntelligent Precision Cooling For Data Center Equipment
The Intelligent Data Center Cooling Solution:Liebert CRV Trust the industry leader in PrecisionCooling to deliver the right solutionfor your data center:In 2002, Emerson Network Power’s Liebert XD family was the industry’s first row-based coolingsystem. Now, we have taken more than 40 yearsof engineering experience and the most advancedtechnologies to design the Liebert CRVrow-based precision cooling system.For maximum application flexibility, Liebert CRV isavailable in multiple capacities and configurations: 600mm wide: 20kW or 35kW air or water/glycolbased, or 40kW chilled water-based cooling units 300mm wide: 19.6kW air cooled, or 30kW chilledwater-based cooling unitsAlways informed:The Liebert iCOM display shows the inlettemperature of the protected racks, tracksother critical information that keeps IT personnelup to date on system operation, and allowsthe Liebert CRV to optimize cooling for therack-based equipment.Easy to deploy and maintain:Row-based placement puts cooling at the heatsource, with adjustable baffles on the CR019,CR020, CR035, and CR040 models that ensurecool air reaches the servers, while logicalplacement of reliable components results in easeof service.Intelligently efficient:Variable speed fans, variable capacity digitalscroll compressor on compressorized modelsand the advanced Liebert iCOM control systemall work together to provide energy savings overtraditional perimeter cooling systems.2600mm (24”)cabinet: 20 or 35kWair or water/glycolcooled; 40kW chilledwater cooled.300mm (12”)cabinet: 19.6kWair cooled300mm (12”)cabinet: 30kWchilled watercooled.
Put Precision Cooling In The RowTo Reduce Energy Consumption and OptimizeOperating Conditions For IT EquipmentThe Liebert CRV is a precisioncooling system that installswithin a row of data centerracks—close to the server heatsource—for the most efficientcooling of critical IT equipment.The rack-sized Liebert CRVprovides high capacity cooling ina small footprint and features theLiebert iCOM Control Systemthat modulates unit performancein real-time, based on conditionsin the row. Monitoring up to10 racks with 20 sensors, theLiebert CRV precisely controlsair temperature, humidity andfiltration in the surrounding racks.Liebert IntelliSlotTMCommunicationCards can be accessedwithout entering thehigh voltage paneland allow the systemto communicate withremote infrastructuremanagement systems.Variable EC Fansregulate airflow andreduce the fan inputpower; resulting in upto 50% less power usedby the fans comparedto traditional perimetercooling.High PerformanceAir Filters are easilyaccessed through theback of the unit.R-410A Refrigerant isenvironmentally friendlyand meets the latestgovernment standards.Liebert iCOM Control presents upto 11 temperaturemeasurements and unitperformance in an easyto understand graphicalsummary.Rack Sensors provide twotemperature readingsper rack to ensure theproper amount of cold airis provided to eliminatehot spots.Adjustable Baffles on the24 in. (600mm) wide modeldirect airflow right, left orboth directions, and left andright on the CR019 model,allowing you to easily changethe airflow distribution asyour cooling needs change.Slanted, BlueHydrophilic Cooling Coilwith intermediate drainpans, quickly disbursescondensation, thuspreventing carryover ofwater into the cold aisle.Digital Scroll Compressor oncompressorized models enables thevariable cooling capacity to precisely matchchanging cooling demand without cyclingon and off, reducing energy consumptionand extending compressor life.3
Liebert iCOM Controls:Optimized Performance,Reliability, and EfficiencyThe Liebert iCOM control system provides advancedcontrol and monitoring capabilities to LiebertCRV units, allowing up to 32 cooling units towork together as a single system to optimize roomperformance and improve energy efficiency. LiebertiCOM controls offer a variety of advantages, includingicon-based navigation, adjustable control algorithms,and data center monitoring capabilities.The Large Graphic Display features a320x240 dot matrix screen operates withintuitive images rather than pages of text. Thisdisplay can be used to control a single coolingunit or any cooling unit on a network.Control Advanced control algorithms allow the airflow and cooling tobe modulated independently, eliminating excessive operations. Temperature sensors attached to server racks allow theoptimal amount of air and cooling to be provided without anyincreased risk for hot spots. Multiple Liebert CRV units communicate with each other tooptimize system performance while reducing noise and airflow,to provide a work-friendly environment. Six control modes of operation allow the Liebert CRV to becustomized for any application.Bar graphs show the inlet temperatureof every rack with a 2T temperaturesensor.Monitoring Six selectable status screens allow you to customize howsystem information is presented. Up to 20 rack temperatures may be summarized using bargraphs or a drawing of the data center on the local display, or alldata may be reported remotely, providing users with a built-inmini-monitoring system. All unit information may be reported remotely through avariety of protocols, including HTTP, SNMP, RS-485 Modbus ,BACnet IP and Liebert SiteScan Web 4.0 Protocol.Predictive Wellness/Maintenance Enhances reliability with predictive analysis of componentsand performance – advance notice allows proactivemanagement of system maintenance. Event logs store the last 400 messages to enrich unit historyand enhance support.Line graphs show the historicaltemperature and humidity conditionsfor the past 8 minutes to 16 days.Service and Spare Parts History On-board service history allows prompt access to records forservice personnel. On-board spare parts list provides convenient identificationof the appropriate unit spare parts and part numbers for fasterservice and support.A single view shows the average,minimum, and maximum temperatureof every 2T rack sensor in a single- ormulti-unit system.4
Designed For Reliabilityand Energy EfficientOperationReduce operating costs and energy consumptionThrough the use of advanced control algorithms, the Liebert iCOM control system is able to leverage the energy efficiency of the EC plugfans and digital scroll compressor to provide greater energy savings atthe system level than other row-based units.Rack SensorsTwo temperature sensors are placed at the inlet of up to 10 racks. Liebert CRV reads the sensors andadjusts airflow and temperature to ensure the proper operating conditions for the rack equipment.Liebert IntelliSlot Communication CardsThe Liebert CRV includes two Liebert IntelliSlot card slots for easy plug-in of optionalcommunication cards:Liebert IntelliSlot Unity-DP Card Delivers SNMP and HTTP web-management communications capabilities for monitoring andcontrol through your existing network with no additional software required. Allows remote monitoring and control of Liebert CRV using RS-485 Modbus through LiebertSiteScan Web or your existing Building Management System. Also enables Modbus IP/BACnetIP for Liebert CRV. Supports Emerson Protocol for communicating with Trellis and Liebert Nform softwareapplications, and LIFE Technology for supporting Remote Service Delivery applications.Liebert IntelliSlot SiteLink-E CardLiebert SiteScan Web 4.0 Protocol Card for SiteLink-E connectivity from Liebert CRV.Digital Scroll Variable Capacity CompressorThe exclusive Digital Scroll Compressor uses the latest control technology to deliver preciseoperation and significantly higher energy efficiency than other compressor technologies.
