9 The 300 series and 600 series provide all the necessary functions of a Thermal Management unit, including cooling, dehumidification, air filtration and condensate Management . The 600 series is also capable of Liebert CRV is to be applied in hot-aisle-cold-aisle configurations. Air enters this unit from the hot aisle, is filtered, cooled and conditioned, then expelled into the cold Liebert CRV is optimized for maximum cooling capacity in a minimal footprint. The extremely energy efficient components of the System are managed by the Liebert icom control System . The control monitors the environment in real-time with sensors on the inlet of the racks the unit is cooling. This information allows the unit to optimize its operations for both performance and energy operations and sensor data can be reported remotely via a variety of communication protocols, providing end users with a built-in rack temperature monitoring System .

10 The supply air baffle on the 600 series allows the air leaving the cooling unit to be directed to the racks the Liebert CRV is conditioning; maximizing its effectiveness, reducing the chance for hot spots and improving the overall System efficiency. The angle and spacing of the baffle vanes have been optimized through CFD modeling, laboratory testing and real-world installations. All service and maintenance is performed through the front and rear of the unit, including all component replacement. All piping and electrical connections are made through the top or bottom of the 1 Unit configurationsSeriesWidthConfigurationNo minal CoolingCapacity, kWInput Power60Hz60024in.(600mm)Air-Cooled20208V - 3ph460V - 3phWater / Glycol CooledAir-Cooled35 Water / Glycol CooledChilled Water4030012in.(300mm)Air-Cooled19208/23 0 - 1phChilled Water30208/230* - 1ph34* Control transformer can be re-tapped to provide 240V - 1ph - 60 HzProduct Description/ConfigurationsLiebert CRV 6 Figure 4 Liebert CRV, front and rear viewsRearFrontRearFront600mm (24 inch) DX and CW Models300mm (12 inch) DX ModelsFrontRearLiebert CRV 300mm (12 inch) CW ModelsAir-Cooled Systems7 Liebert CRV and Physical Data Air-Cooled SystemsTable 2 Performance data 600mm (24 inch) unitsReturn Air TemperatureStandard 95 F (35 C) Ambient CondenserCR020 RACR035 RALiebert Finand TubeCondenserLiebert MC CondenserLiebert Finand TubeCondenserLiebert MC Condenser 105 F DB, 71 F WB ( C DB, C WB) 17% RHTotal kBTU/H (kW) ( ) ( ) ( ) ( )Sensible kBTU/H ( ( ) ( ) ( ) ( ) 100 F DB, F WB ( C DB, C WB) 20% RHTotal kBTU/H (kW) ( ) ( ) ( ) ( )Sensible kBTU/H ( ( ) ( ) ( ) ( ) 95 F DB, F WB (35 C DB, C WB) 23% RHTotal kBTU/H (kW) ( )))
