Emerson Network Power has introduced extended sizes of the Liebert® MC microchannel condenser. The Liebert MC condenser is the quietest, most efficient condenser available in the data center industry, and features advanced controls that provide a higher level of IT equipment protection. The Liebert MC condenser is now available globally.

The Liebert MC microchannel coil condenser is 50% more efficient and provides a higher level of data center protection than traditional fin and tube condensers. It leverages advanced controls within the outdoor condenser that monitor outdoor temperatures and fan and compressor speeds, and it communicates directly with the Liebert iCOM™ controls within the data center to optimize protection and efficiency. The exclusive microchannel coil design and electrically commutated (EC) variable speed fans offer highly efficient, IT system-matched heat rejection that reduces energy costs and operational expenses and enables a lower total cost of ownership (TOC).

The normal quiet operation of the Liebert MC condenser results in a 2.5 to 5.5 dBA lower sound level than alternative condensers. The Quiet-Line mode of operation is controlled by the Liebert iCOM indoor unit to operate Liebert MC condenser’s fans at reduced speeds, based on time of day if desired. This yields 10 - 20 dBA lower sound level, allowing installation in regulated environments. In addition, the condenser requires up to 70% less refrigerant charge and is 40% lighter than standard condensers, making it easier and less costly to install.

“As IT budgets constrict, data center managers are searching for new, higher levels of energy efficiency and protection,” said John Peter Valiulis, vice president, North America marketing, thermal management, Emerson Network Power. “The Liebert MC condenser is a major technology breakthrough in an area of data center thermal management that is often overlooked. The advanced controls and innovative technology on the condenser help deliver the highest efficiency gains than any other condenser on the market.”

The Liebert MC condenser offers flexibility with multiple voltage configurations available to match electrical needs and compatibility with R-410A, R-407C and R-22 refrigerants. The condenser is ideally suited for use with the Liebert CRV, Liebert Challenger 3000, Liebert DS and Liebert DSE thermal management systems.
