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.
Features:
- The most energy-efficient heat exchanger, operating PUE as low as 1.03
- Maximize the operating hours of dry conditions each year while minimizing the water consumption of young people to the greatest extent possible
- Low peak power can reduce the capacity of backup generators
- Improve productivity through advanced control and monitoring
- Lowest operating costs and increased profitability
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.
