For Business-Critical Continuity
™
As The Temperature Rises — So Does Your Risk
Every operation of your company depends upon the instant
around-the-clock availability of computers, servers and other electronic
systems. If they aren’t working, neither is your company. Unfortunately,
every piece of IT equipment your company possesses produces heat.
And if you don’t get rid of the heat, you are going to have problems.
The first step in taking control of this situation is to understand the threats to your
system reliability — and exactly what you can do about them.
You Face Many Challenges In The Pursuit Of Business Continuity
But There Are Real Solutions
Mission-Critical Cooling Provides
Protection Under All Conditions
Yes, computers have changed — but
the threats to their operation are
as real as ever. An air conditioning
system that maintains the
temperature and humidity at the
proper levels in your critical facility is
an absolute necessity for the viability
of your business.
Mission-Critical Systems Keep
Moisture And Air Cleanliness
Right Where They Need To Be
Ordinary building air conditioning
and heating systems are designed
to keep people comfortable.
Computers and other sensitive
electronics require a system that
provides humidity control to meet
equipment specifications — and air
filtration designed to keep airborne
particles from causing problems.
Because Every Facility Is Unique, Mission-Critical Systems Are
Designed To Meet The Cooling Needs Of Any Critical Space
A mission-critical cooling system can be engineered to match just about
any type or size of facility. There are downflow systems for raised floor
facilities and upflow units where the floors are not raised. Supplemental
systems can be used where equipment is tightly packed in racks.
Compact models are ideal for small or remote facilities.
Mission-Critical Cooling Systems Are Engineered To Get The Most
From Every Energy Dollar
Energy efficiency is no longer just an option for users of air conditioning

Headline
You Need To Start With The Right Kind Of Cooling
Some operations may be tempted to utilize standard comfort cooling systems to save money or to avoid using additional floorspace
within their facility. But while these moves may provide some benefits in the short term — they must be balanced against the
cost of potential downtime and equipment damage caused by serious overheating, as well as the risk of financial loss.
Why Comfort Air Conditioning
Should Make You Uncomfortable
Standard building air conditioning is designed for
one thing: to keep people comfortable. In most
cases, this is done 8-12 hours each day, five days a
week and only during the warmest months. These
units are simply not built to handle the 24 hour-aday operation associated with computer rooms and
communications facilities.
The Protection Never Stops
Mission-critical cooling systems are designed to run
the same hours as your network — continuously, year
in and year out, around the clock. These systems are
specifically designed to maintain both temperature
and humidity levels to equipment manufacturers’
specifications, which are several times more
stringent than those designed for the human body.
Removing Heat Without Removing
The Humidity
The biggest problem with ordinary air conditioning
systems is they are designed for the comfort of
people — not the protection of computer-based
electronic systems. Unlike people, computers
generate dry (also called sensible) heat, but
not humidity.
With a large percentage of their total capacity
devoted to the removal of moisture, comfort systems
can lower room humidity far below acceptable
standards for electronic equipment — and they have
no provisions for adding moisture. To correct this
situation, precision air conditioning systems typically
have a high ratio of sensible-to-total cooling capacity
to remove heat from the air. This allows for much
lower operating costs since the type of cooling is
matched to the load. These units also use integrated
humidification systems to provide the necessary level
of moisture control.
Comfort Air
Using rigid, overhead ducts
provides insufficient air volume
(350-400 CFM/Ton) which
results in hot spots. They are
also difficult to relocate.
Minimal air filtration
is typically provided
with comfort systems.
4
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.
Normalized Power Consumption
Headline
What Makes A Mission-Critical Air
Conditioning System So Different?
There are several key areas that differentiate mission-critical
cooling from ordinary comfort air conditioning systems.
Each of these performance criteria has a major impact on the
proper environmental protection of your critical facility.
Temperature And Humidity Control
Mission-Critical Systems are specifically designed to
handle the heat loads generated by electronic equipment.
They utilize fast-response microprocessor control systems
to adjust quickly to changing conditions within the
room, while providing you with complete supervision of
temperature and humidity at all times. Emerson Network
Power lets you choose from several humidification
methods including integral infrared and steam
generation units.
Air Flow Management
Providing the proper volume of air to the specific location
in a data center is as important as the temperature control.
Mission-Critical Systems are designed to handle a wide
range of static pressures within the duct work or under
floor plenium to address this important requirement.
Operating Efficiency
The higher Sensitive Heat Ratio (SHR) of Mission-Critical
Systems results in lower energy operating costs vs. comfort
systems. Four-Step, GLYCOOL™ and Dual-Cool options offer
even more energy efficiency. These enhancements increase
the performance level of the system and more closely track
the cooling load of your critical space.
