LIEBERT® CRV

INTELLIGENT PRECISION COOLING FOR DATA CENTER EQUIPMENT

Liebert CRV Delivers Efficiency Without Compromise™

Efficiency Without Compromise provides a path to optimize data center infrastructure around design, operating and management efficiencies – while maintaining or improving availability. This is archieved through the proper selection and utilization of cooling, power and monitoring technologies, supported by key services and local expertise.

Liebert CRV the Intelligent Data Center cooling Solution

Trust the industry leader in Precision Cooling to deliver the right solution for your data center:
In 2002, Emerson Network Power’s Liebert XD family was the industry’s first row-base4d cooling system. Now, we have taken more than 40 years of engineering experience and the most advanced technologies to design the Liebert CRV row-based precision cooling system.

Always informed:
The Liebert iCOM display shows the inlet temperature of the protected racks, tracks other critical information that keeps IT personnel up to date on system operation, and allows the Liebert CRV to optimize cooling for the rack-based equipment.

Easy to deploy and maintain:
Row-based placement puts cooling at the heat source, with adjustable baffles that ensure cool air reaches the servers, while logical placement reliable components results in ease of service.

Intelligently efficient:
Varialble speed fans, variable capacity digital scroll compressor and the advanced Liebert iCOM system control all work together to provide energy savings over traditional perimeter cooling systems.

Liebert DM delivers enterprise level precision cooling to small computer rooms and network closets. It is designed for yearround temperature and humidity control for IT applications across the critical infrastructure.

The Liebert DM offers a selection of variants to fit your infrastructure’s requirements and conditions. It also features communication capabilities to the critical infrastructure manager for easy monitoring of the temperature across the IT infrastructure.

The Liebert DM variants:

• Air Cooled / Water Cooled
• 16kW Air Cooled Capacity
• Chilled Water

The Liebert PEX is the Next Generation Precision Environmental Control System from Emerson Network Power. It is a result of extensive research and development, conducted with leading environmental control experts, consultants and major corporations. A wide range of standard units offered from 20 KW to 100 KW in Upflow & Downflow Configurations.

Key Features Contributing To the Superior Efficiency Of The Liebert PEX

1. EC Fan
   The EC fan technology regulates airflow and reduces the fan input power. In-floor configuration further reduces energy consumption in downflow units. This significantly reduces energy consumption and provides longer component life. Managed through Liebert iCOM controls, EC fans deliver airflow for the optimal operating conditions for IT equipment.
2. Digital Scrolll Compressor
   Liebert PEX with Digital Scroll Technology is highly reliable and is designed to achieve efficiency with flexibility and to lower TCO. The use of digital scroll technology actively manages capacity modulation from 20 percent to 100 percent. During the loaded state, cooling units consume full load power. On the other hand, during the unloaded state, the units run freely, consuming only about 10 percent of the full load.
3. iCON Controller
   The teamwork mode in the iCOM Controller, a key feature of the Liebert PEX, ensures efficiency by allowing multiple units to work together as a single system to optimize room performance.
4. Infrared Humidifier
   The Infrared Humidifier has been a feature on Liebert environmental control systems for over 45 years. Its rapid response and the ability to handle varying water conditions has made it an industry standard in applications that demand precise, particle-free humidity control.
5. Dual Cool Option
   This option a provides a second coil that utilises the central building Chiller system water supply. The unit can function either as a DX (compressorized) or a Chilled water system. During times when the chiller supply is available compressorized operation is eliminated, reducing energy costs. In addition this option can provide increased redundancy and flexibility to the environmental control system.
6. Free Cool Option
   Optional GLYCOOL free-cooling system permits compressorless operation in colder ambient conditions.
