Vertiv™ Liebert® EFC, Composite HE, Indirect Evaporative Freecooling Solution
The system includes indirect air-to-air heat exchange and evaporative cooling technology all in one footprint. The Liebert® EFC, Composite HE, is capable of reducing air temperatures by leveraging on the evaporative cooling principle and now, with the new composite heat exchanger designed for data center applications, it provides higher efficiency together with and increased robustness and reliability. Through this technology, the Liebert EFC can thus achieve pPUE levels of 1.05 ensuring top energy efficiency, as well as minimized operating costs.
