We Invented Precision Cooling
Emerson Network Power knows precision cooling. After all, we invented it back in 1965!
Over the years, our cooling systems have been proven as the world’s standard for reliable
operation. In fact, there are Liebert precision cooling systems in the field that have been
in constant use for over 30 years. Installed in thousands of critical data centers around
the world, our latest precision cooling portfolio offers the highest efficiency without
compromising reliability.
Understanding the 3 R’s of Precision Cooling
Despite the claims of different vendors promoting their own, specialized solutions, there is no silver bullet when it comes
to precision cooling for every application. There is only the most appropriate cooling solution for your infrastructure, and
an understanding of each cooling design can help determine which cooling approach and solution can best meet your
business goals and infrastructure requirements.
Room Cooling
While densities are climbing steadily, standard density facilities remain the norm. Traditional
room cooling uses precision air conditioners and is the most appropriate solution for these
standard density environments. The standard complexity, ease of deployment and precision
humidity and filtration control of these systems has seen hundreds of thousands of units
deployed in critical facilities across Asia, with more added every day. Combined with a raised
floor, precision air conditioners deliver the best value for money and represents significant
increased efficiency over building or comfort cooling.
Row Cooling
If energy efficiency is top concern, row cooling can improve efficiency over the standard room
approach by more than 30 percent. It supports high density applications by the utilization
of cold aisle containment. Row cooling with SmartAisle™ can further improve efficiency and
provide uniform and predictable temperature and humidity control to equipment with or
without raised floor.
Rack Cooling
One of the proven best-practice approaches to dealing high density heat issues is by bringing
cooling technologies closer to the source of heat. Specialized precision cooling solutions
for racks can support ultra-high-density applications, up to and above 30kW per rack. This
dedicated cooling approach specifically cools a rack by providing the best direct air flow intake
of the critical equipment.

Liebert PEX
The Liebert PEX: More Than A Single Energy Efficient component
„
„

The efficiency of the Liebert PEX is engineered into the product. Each component that goes into the Liebert PEX is
carefully tested to ensure that it will contribute to its overall efficiency.
All enchancements to energy efficiency are designed to reduce operating time and cycling of key components and
increase reliability.
In addition to having components that are individually engineered to provide the best efficiency, how these
components work and interact with each other also contribute to the energy savings you get with the Liebert PEX.
The EC fan technology regulates airflow and reduces the fan
input power. In-floor configuration further reduces energy
consumption in downflow units. This significantly reduces
energy consumption and provides longer component life.
Managed through Liebert iCOM controls, EC fans deliver
airflow for the optimal operating conditions for IT equipment.
Liebert PEX with Digital Scroll Technology is highly reliable
and is designed to achieve efficiency with flexibility and
to lower TCO. The use of digital scroll technology actively
manages capacity modulation from 20 percent to 100
percent. During the loaded state, cooling units consume full
load power. On the other hand, during the unloaded state,
the units run freely, consuming only about 10 percent of the
full load.
The teamwork mode in the iCOM Controller, a key feature
of the Liebert PEX, ensures efficiency by allowing multiple
units to work together as a single system to optimize room
performance.

The Infrared Humidifier has been a feature on Liebert
environmental control systems for over 45 years. Its rapid
response and the ability to handle varying water conditions
has made it an industry standard in applications that demand
precise, particle-free humidity control.
Utilising this option a Liebert PEX provides a second coil
that utilises the central building Chiller system water supply.
The unit can function either as a DX (compressorized) or a
Chilled water system. During times when the chiller supply is
available compressorized operation is eliminated, reducing
energy costs. In addition this option can provide increased
redundancy and flexibility to the environmental control
system.
Optional GLYCOOL free-cooling system permits
compressorless operation in colder ambient conditions.

Why Precision Cooling?
Traditional approaches to cooling are only effective and efficient to a point. Unfortunately, a number of IT organizations
still rely on commercial air conditioners to cool their critical facilities. Commercial air conditioning, known for its low
upfront costs, is both ineffective and problematic. It does not address the needs of sensitive electronics such as year-round
cooling, humidity & temperature control and air filtration, which makes Precision Cooling the only real solution for these
applications.
Comfort Cooling vs. Precision Cooling
Comfort Air
Using rigid, overhead ducts
provides insufficient air volume
(30-40 l/s per kW) which
results in hot spots. They are
also difficult to relocate.
Minimal air filtration
is typically provided
with comfort systems.
Comfort systems can over-dry
room air because of their
lower Sensible Heat Ratio.
They typically do not provide
integral humidity control.
Using separate humidification
systems, not controlled by
the cooling system, can
waste energy and reduce the
stability of the environment.
Comfort cooling systems are not designed for continuous operations. These systems lack the scalability, adaptability
and precision required to effectively cool the server racks being deployed today.
Precision Cooling Air
Precision cooling provides a cost-effective, energyefficient solution to the requirements of today’s
sensitive electronics, while enabling the flexibility
to adapt to whatever the future brings.
Why run the risk of relying on building air?
„
„
„
„
„
„
RISK: These systems shutdown over night & weekends
RISK: Systems designed to operate 5 x 8 vs. Continuous Operation.
RISK: Do not provide sufficient filtration for IT equipment and no humidity control
RISK: Building air removes too much moisture, introducing the risk of static discharge
RISK: Insufficient airflow causes overheating in IT equipment (Airflow designed for comfort not
correct delivery for IT)
COST:
- Building air is designed to cool people (heat and sweat)
- As a consequence a lot of energy (cost) goes into removing that moisture
- This energy is wasted where building air is used to cool machines

Digital Scroll
Liebert PEX with Digital Scroll technology is highly reliable and is designed to achieve efficiency with flexibility and to lower
TCO. Emerson Precision Cooling units with Digital Scroll technology actively manage achieving capacity modulation from
20 percent to 100 percent. During the loaded state, cooling units consume full load power. On the other hand, during the
unloaded state, the units run freely, consuming down to about 10 percent of the full load. Scalable, the Liebert Digital Scroll
automatically adjusts to yearly increases in heat load. It is available on air cooled, water cooled, glycol cooled, dual cool and
free cool models.
Single compressor models utilize Digital Scroll compressor while dual compressor models utilize two Digital Scroll
compressors to provide the maximum energy benefit at part loads and system cooling and dehumidification cycles.
