CW051 AND CW060 MODELS:

USE THE HEX-HEAD SCREWS REMOVED IN STEP 5 TO SECURE THE FAN MODULE DIRECTLY TO THE CENTER FRAME SUPPORT. SCREW CLEARANCE HOLES ARE PROVIDED IN THE FAN MODULE. THE "Z" BRACKETS WILL ONLY BE USED TO SECURE THE FAN AT THE OUTTER ATTACHMENT POINT.

LIEBERT DS, CW146 AND CW181 MODELS:

USE THE HEX HEAD SCREWS REMOVED IN STEP 5 TO SECURE THE FAN MODULE DIRECTLY TO THE FRAME. SCREW CLEARANCE HOLES ARE PROVIDED IN THE FAN MODULE.

NOTE: NOT ALL HARDWARE REMOVED IN STEP 5 WILL BE USED TO RETAIN FANS IN LOWERED POSITION.

8.REPEAT STEPS 3-7 TO LOWER REMAINING FAN MODULE(S) IF PRESENT.

NOTE: THE FANS MUST BE OPERATED IN EITHER THE FULLY RAISED POSITION OR FULLY LOWERED POSITION. NO OTHER COMBINATION OF FAN POSITIONING IS SUPPORTED.

The Liebert CW146, CW181, CW038, CW076 thru CW114, CW051, CW060, and CW041 models represent a series of precision cooling solutions designed to meet the demanding requirements of today’s data centers and critical environments. Each model is tailored for high-performance cooling while ensuring energy efficiency and reliability.

One of the key features of the Liebert CW series is their modular design. This allows for flexible installation configurations, enabling cooling systems to be easily integrated into existing facilities. The units can be deployed in various arrangements, including a dedicated or shared cooling approach, accommodating changes in the cooling load as data centers expand or evolve.

The cooling technologies employed in these models include chilled water cooling, which is particularly effective in maintaining optimal temperatures in high-density environments. The use of chilled water systems allows for more efficient heat transfer, reducing energy consumption compared to traditional air-cooled systems. Additionally, the ability to leverage existing chilled water infrastructure can help minimize capital expenditures.

Among the standout characteristics of the Liebert CW models is their advanced control systems. These controls include microprocessor-based management, facilitating precise temperature and humidity control. This level of precision is crucial for protecting sensitive equipment and ensures that cooling performance can be adjusted in real time based on varying load conditions.

Furthermore, the Liebert CW series units feature variable speed fans and pumps, which not only improve energy efficiency but also enhance operational efficiency. By automatically adjusting fan and pump speeds, the units can optimize airflow and cooling capacity based on the specific demands of the environment, reducing energy waste while maintaining performance.

The construction of the Liebert CW models is another notable aspect. They are designed with robust materials that enhance durability and longevity, ensuring reliable operation in demanding conditions. Additionally, the seamless integration of environmental monitoring systems helps track performance and detect potential issues before they escalate.

In summary, the Liebert CW146, CW181, CW038, CW076 thru CW114, CW051, CW060, and CW041 offer a comprehensive suite of features aimed at delivering efficient, reliable cooling for data centers and critical environments. With their modular design, advanced control mechanisms, and energy-efficient technologies, these models stand out as ideal solutions for businesses looking to protect their critical assets while managing operational costs effectively.
