Emerson Network Power Extends Line of Row-Based Cooling Systems

New Liebert® CRV Model Provides All the Cooling Capacity in Half the Space

COLUMBUS, Ohio  – Emerson Network Power, a business of Emerson (NYSE: EMR) and a global leader in maximizing availability, capacity and efficiency of critical infrastructure, today introduced the Liebert® CRV row-based cooling system in a smaller, 12-inch (300mm) footprint. The new Liebert CRV delivers superior efficiency with industry leading capacity per square foot to support small data centers and network closet applications. The compact cooling unit is available now for applications in North America. 

The new Liebert CRV model is an air-cooled, direct expansion (DX) unit with a nominal cooling capacity of 19.6 kW. It offers double the footprint capacity of the standard air-cooled row-based system, and fits seamlessly within a row of racks to deliver energy efficient, high capacity cooling close to the server heat source. The Liebert CRV contains a digital scroll compressor and variable speed fans, managed by Liebert iCOM technology, to deliver capacity-matched operation and enhanced efficiency. The digital scroll compressor features modulation to match changing cooling demand without cycling on and off, while reducing energy consumption. Five variable speed fans regulate airflow and reduce the fan input power based on the IT load, using up to 50 percent less power than centrifugal fans or two-stage fans that are typical in these applications.

“With the industry’s highest delivered row-based efficiency and most advanced control and performance, the Liebert CRV is an ideal solution for data center managers looking to reduce energy consumption and optimize operating conditions for IT equipment,” said John Schneider, vice president and general manager, thermal management, Emerson Network Power. “The new 300mm DX version of the Liebert CRV product line allows data centers to have a high capacity and high energy efficiency row-based cooling system in just half the footprint of a standard row-based system.”

The integrated Liebert iCOM control system adds intelligent control capabilities that allow the unit to adapt quickly to changing environmental conditions. It provides advanced control and monitoring capabilities that allow up to 32 cooling units to work together as a single system to precisely control temperature and humidity across a room while optimizing the efficiency of the entire cooling system. The system utilizes up to 20 rack sensors per unit to monitor conditions, including variations in temperature and humidity for up to 10 racks, and smoothly adjusts the cooling output to match the conditions.

Designed for hot-aisle/cold-aisle configuration, the Liebert CRV can be installed in data center or network environments with raised or non-raised floors. Two Liebert IntelliSlot communication card slots allow easy plug-in for multiple modes of communication and control. It is compatible with Emerson Network Power’s data center infrastructure management (DCIM) system, the Trellis platform, as well as the Liebert Nform and Liebert SiteScan monitoring and reporting systems.
