Liebert® EFC, the Highly Eicient Indirect Evaporative Freecooling Solution

The Liebert EFC is equipped with the most advanced industry technology. The system includes indirect air-to-air heat exchange
and evaporative cooling technology all in one footprint. The Liebert EFC is capable of reducing air temperatures by leveraging on
the evaporative cooling principle.

The process involves the evaporation of water which, as a consequence, cools the surrounding air. Through this technology, the
Liebert EFC can thus achieve pPUE levels of 1.03 ensuring top energy eiciency, as well as minimized operating costs.

Liebert® EFC: Enhancing Data Center Eiciency

Evaporative Cooling

The highly eicient evaporative system
sprays water onto the heat exchanger to
enable cooling even at high ambient air
temperatures, without the need for
mechanical cooling.

Highly Eicient EC Fans

The new generation of fans installed in
the Liebert EFC dramatically reduce the
noise level and increase the overall
eiciency of the unit.

Reduced CO2 Emissions

At pPUE levels of 1.03, Liebert EFC
requires minimum power input
consequently reducing CO2 emissions.

Energy Eiciency

The evaporative cooling technology
enables Liebert EFC to reach pPUE
levels as low as 1.03.

Eurovent Certified Heat Exchanger

Eurovent certification guarantees that
Liebert EFC heat exchangers undergo
independent testing, thus delivering
rating accuracy and enhancing the unit's
reliability.

Freecooling

Evaporative cooling extends indirect
freecooling operation all year round.

Data Center Free from
Contaminations

The air-to-air heat exchanger separates
external and internal air, protecting the
data center air from bacterial
contamination, as well as other external
events such as fire and pollution.

Liebert® iCOM™

Liebert® iCOM™ Control ensures high level
management of the units to work together
as a single system, thus optimizing room
temperature and airflow.

Integrated Chilled Water Coil and
Direct Expansion System

These technologies ensure the unit's
operation even in climates characterized
by extreme humidity levels or severe
temperature peaks.

Partial Load Eiciency

New generation EC fans and integrated
digital scroll compressors contribute to
achieving the highest eiciency levels at
partial load.

4

The evaporative system has a dedicated internal pump that provides the water needed.

Water is sprayed through special nozzles onto the heat exchanger and evaporates, thus humidifying and cooling the air.
