Indirect evaporative freecooling units, equipped with the most advanced industry technology, including indirect air-to-air heat exchange and evaporative cooling technology all in one footprint, ensuring top energy efficiency and minimized operating costs.


A New Heart Composite Heat Exchanger: the heart of Vertiv™ Liebert® EFC is its air-to-air heat exchanger, specifically thought for data center applications, protecting air from bacterial contamination or pollution. Thanks to its reduced pressure drop, new plate pattern with high heat exchange and together with new composite material, this new heart is designed for industry’s maximum efficiency for the entire lifetime of the unit without any compromise on reliability. You’ve Got the Power: Take advantage of Liebert® EFC cutting-edge design to achieve economization even in the worst conditions and of the industry’s lowest peak power usage vs any other DX systems thus requiring smaller electrical infrastructure through free cooling available also at high temperatures. Low air leakage design eliminates the need for additional fan power with no volumetric displacement and facilitates important savings. Unsurpassed Efficiency: Achieve your sustainability goals by reducing operating costs and carbon footprint without compromising your profitability for an unsurpassed efficiency with a pPUE below 1.05. Thanks to advanced software controls and latest EC fan design, enjoy lower energy bills and minimize sound emission. Fitting Seamlessly: Liebert EFC comes with a reduced footprint and multiple air configuration options enabling you to easily fit the unit up to your building in rooftop, perimeter or multi-storey deployments.Scale with Confidence: Liebert EFC is designed for minimal maintenance and allows no white space occupation. The perfect solutions to allow for scalable deployments. All Under Control: Leverage the Vertiv™ Liebert® iCOM™ thermal controls to monitor temperature, humidity, pressure, power utilization, and much more its advanced algorithms seamlessly manage automatic transitions among the most suitable working modes and protect against water freeze. Liebert® iCOM™ Control ensures the high-level management of the units to work together as a single system, thus optimizing room temperature and airflow.


Direct Expansion System or Integrated Chilled Water Coil: These technologies ensure the unit's operation even in climates characterized by extreme humidity levels or severe temperature peaks Advanced Vertiv™ Liebert®​ iCOM™Control: Ensures high level management of the units to work together as a single system, thus optimizing room temperature and airflow. Furthermore, it features a new 10” touch screen display for quicker and easier data readability Vertiv™ SmartAisle™ Control and Other Embedded Logics: Optimize internal air volumes and temperature according to specific server needs, ensuring that not a single Watt is wasted Patented, Composite Heat Exchanger: minimizes the aerodynamic impact of the internal parts ensuring a significant reduction of the pressure drop providing unsurpassed annual efficiency and higher maximum air flow versus previous configurations equipped with legacy HE.
