Vertiv™ Liebert® EFC low-GWP - The next generation indirect evaporative free cooling unit From 100 to 450 kW
Vertiv™ Liebert® EFC with low-GWP refrigerant is the next generation, indirect evaporative free cooling unit designed to cool data center applications with the future in mind. It combines the capabilities of indirect air-to-air heat exchange and evaporative cooling principles in one single unit. Together with the new composite heat exchanger, the new inverter technology with low-GWP R454B, the multi-step evaporative system, the new DX priority control logic functionality and with the WET and DX priority dual modes, it provides even higher efficiency, guarantees compliance with major bans and regulations worldwide for years to come and proves to be as a turnkey solution for rapid deployment facilitating scalability and easy maintenance. Through this cutting-edge, patented technology, the Liebert® EFC can thus achieve pPUE levels of 1.05 allowing data center owners to reach top energy efficiency, as well as minimizing their operating costs.
