Liebert CRV

Liebert CRV - PD - 265086 - 11.01.2018

3.1 Standard features

Air cooled models

DX COOLING COIL

 It is constructed of copper tubes and hydrophilic coated aluminium fins. The hy

-

drophilic coating provides superior water carryover resistance. A stainless steel condensate drain pans 

are provided.

REFRIGERATION SYSTEM

 Single refrigeration circuit includes a liquid line filter drier, a refrigerant 

sight glass with moisture indicator, an electronic expansion valve, and a liquid line solenoid valve.

COMPRESSOR

 The compressor is an R410A DC inverter scroll type with variable capacity operation 

from 30-100%. The limit of capacity variation is depending by the installation type and the room condi-

tions. The compressor has a suction gas cooled motor, vibration isolators, internal thermal overloads, 

manual reset high pressure switch, low pressure and high pressure transducer, crankcase heater, in-

ternal centrifugal oil pump, and an operating speed of 3000RPM @ 50Hz.

ELECTRONIC EXPANSION VALVE DEVICE (EXV)

 The valve is designed for modulating control of 

refrigerant circuits with high speed and high precision. It is suitable for use as expansion device in 

refrigerant circuits with DC Inverter Scroll compressor, with organic safety refrigerants (i.e. R410A).

For variable capacity systems, an EXV provides superior performance as compared to a traditional 

thermostatic expansion valve (TXV), due to:

• 

Precise flow control

• 

Positioning time

Electronic expansion valve ensure a better control on superheating at the outlet of the evaporator, en-

suring at same that compressor will never be filled by liquid. Moreover the EXV valve let the condensing 

temperature goes down to 33°C.

FAN

 The unit is equipped with five (CR021) or three (CR011) direct driven radial fans with backward 

curved blades and Electronically Commutated DC motors; commonly referred to as EC plug fans.

The fan speed is variable and automatically regulated by the iCOM control through all modes of oper-

ation. Each fan has a dedicated motor which provides a level of redundancy. The fans pull air through 

the coil and are located on the front side of the unit.

iCOM CONTROL SYSTEM

 The Liebert CRV is controlled by the iCOM Control System. The standard 

user interface is the Large Graphical Display (320x240 pixels, backlit) which presents system informa

-

tion and allows all parameters to be viewed and adjusted. It features push-button navigation, operation-

al status LEDs, and a 3-level password protection system. iCOM without display is available as option. 

Unit without display can be controlled through a display of another unit in the same group or through a 

service display. Unit-to-Unit communication with other Liebert CRVs and two IntelliSlot communication 

card housings are included as standard.

2T RACK TEMPERATURE SENSORS

 Consist of a vented case with two temperature probes. Up 

to 10 2T housings (20 temperature probes) can be connected to a Liebert CRV. One 2T housing and 

both sensor probes are to be attached to a rack the cooling unit is conditioning. The sensors provide 

real-time, direct feedback to the cooling unit to optimize the amount of cooling and airflow required; in

-

creasing energy efficiency and ensuring proper rack inlet air temperatures. The sensor data can also be 

reported to remote BMS and monitoring systems. The sensor network consists of one CAN wire leaving 

the cooling unit and connecting to a 2T sensor. Each remaining 2T sensor is connected to the previous 

sensor; often referred to as a daisy-chain configuration.

REMOTE SHUTDOWN TERMINAL

 Provides the customer with a location to remotely shut down the 

unit.

COMMON ALARM CONTACT

 Provides the customer with a set of normally open (n/o) contacts for 

remote indication of unit alarms.

CABINET

 The exterior steel panels are custom powder coated to protect against corrosion. The dou-

ble wall constructed side panels separate the ½”, 2.0 lb/ft3 insulation from the airstream. The unit is 

mounted on casters for quick installation and provided with levelling feet. The perforated inlet and outlet 

panels have 81% open area.

SERVICE ACCESS

 All service and maintenance is performed through the front and rear of the unit; 

including any component removal. No side access is required. All electrical and piping connections are 

made through the top and/or bottom of the unit.

FILTER

 The unit is equipped with two air filters rated G2 following EN779, located within the cabinet, 

and accessible from the rear of the unit. Air filter F5 are available as option. A filter clog alarm is included 

as an option.
