Unlike other grates the DirectAire angles the airflow toward the
equipment achieving a 93% Total Air Capture (TAC) rate by a
standard server rack. This means 93% of the airflow delivered
through the grate is entering the face of the server rack,
providing the highest cooling capacity and energy efficiency of
any grate on the market. The elimination of bypass air saves
operating expenses in existing facilities and reduces capital
expenditures on cooling equipment in new facilities. DirectAire’s
superior load performance is ideal for retrofit and new construction,
easily integrating into your existing raised floor system.

You’ve Never Seen Performance Like ThisDirectAire Improves Heat Load Capacity, Energy Efficiency & Structural Performance
Improve Data Center Financial PerformanceDirectAire maximizes energy efficiency and the overall capacity
of any new or existing data center. The precise delivery of air to
the face of the rack reduces by-pass air allowing new facilities
to in-turn reduce the number of CRAH units. Retrofits can set
CRAH units with fixed speed fans to standby mode or adjust
variable fan drives to operate at a lower static pressure, saving
energy. Likewise the 93% capture rate eliminates the need for a
full containment system. The facilities overall cooling capacity
will also be improved allowing for the addition of IT equipment
without the capital investments on infrastructure.
Easily Cool High Density RacksThe DirectAire features 68% open area, capable of delivering
2,600 CFM at .1” H2O static pressure. More importantly each
vertical vane has an angle of deflection at the top to direct the
airflow towards the server rack. Unlike other grates the
DirectAire’s angle of deflection allows the equipment to achieve a
93% Total Air Capture Rate. This means 93% of the airflow
delivered through the grate is being captured by the server rack
for cooling, compared to typical airflow panels which only deliver
30-50% directly to the rack. The DirectAire’s ability to direct air
where it’s needed most makes this panel ideal for high density
applications with cooling capacity of up to 28.5kW per Rack.
Strong & DurableCooling capacity and energy efficiency are just the beginning of
the DirectAire’s impressive characteristics. With a 1500 lb
Rolling Load the DirectAire’s all steel construction eliminates the
need to move heavy equipment through the hot aisle by
providing the strength to move equipment over the airflow
panels. In addition to high rolling capacity the DirectAire features
a Design Load of 2000 lbs with a Minimum Safety Factor > 2.0
meaning this panel has been designed to handle the most
demanding load applications.
Standard grate requires morestatic pressure due to bypass.
DirectAire cools the samerack with less static pressure.

Eliminate the Burden of Airflow Containment
Containment systems in a data center come with many
challenges including fire code requirements, service distribution
restraints and limited flexibility. Unlike other panels which throw
air straight up in a vertical plume the DirectAire’s angular throw
evenly distributes the majority of the air it delivers directly to the
face of the rack providing effective containment when used in
conjunction with best practices.
The chart shows over a 40% reduction in the Total CFMrequired to cool a typical data center with a 2MW ITload using a typical grate compared to DirectAire.

93% TAC
Total Air Capture & Data Center Airflow
Total Air Capture (TAC) rate refers to the amount of air delivered
through the panel that is then captured by the server rack placed
in front of that panel. The black box below represents a standard
24” x 76” server rack. Lines have been added to show the three
zones of the server rack. Zone 1 represents the bottom of the
rack closest to the floor and Zone 3 represents the top of the
rack farthest from the air supply. You will notice that the
DirectAire grate delivers 93% of it’s 2,600 CFM at .1” H2O to
the face of the server. Furthermore you will notice this airflow is
spread evenly across the three zones of the rack.
DirectAire’s 93%TAC rateenables you to gain near peakairflow without containment.

Typical airflow panels requirecontainment systems to ensuremaximum airflow to the racks.
TAC Reduces Total Airflow Requirements
The total airflow required for cooling the same size data center is
significantly reduced through the increased TAC rate provided by
DirectAire. This reduction in total airflow has a dramatic effect on
the fan energy required to move air throughout the data center.

DirectAire’s ability to deliver high volumes of air directly and evenly across the face of
the server rack gives it the unique ability to handle very high density equipment. The
table below lists cooling capacities per rack based on a mathematical calculation for
systems with and without containment using the following formula (CFM x Total Air
Capture %) / 120(CFM needed to cool 1kW @ 25ºF ) = kW per rack. Laboratory
testing was conducted using heat banks to measure the cooling effectiveness and
verify the calculated kW/rack heat loads. For more info on DirectAire’s load capacity

Improve Your Financial PerformanceDirectAire Offers Energy Efficiency, Capital Investment Reduction and Excellent Payback
The energy savings realized through the use of a DirectAire grate
is made up of two components. The minor component is gained
from the grate’s large open area which allows the same airflow at
a lower static pressure. The second and larger component, is
realized through the DirectAire’s 93% Total Air Capture rate. A
typical uncontained cold aisle configuration assumes more than
50% of the air delivered will bypass the IT equipment. The
DirectAire reduces this bypass air to less than 10% resulting in
tremendous energy savings.

SmartAire™
Efficiently Manage Diverse & Variable Loads
The data center is in constant flux. Load diversity between racks
and variable server loads are the norm. Managing airflow into the
data center space is key to achieving reliability. New demands to
reduce energy consumption in the green data center require a
fine balance to ensure proper air flow to each rack during peak
IT hardware operation, while not over-cooling partial load and
idle states in a diverse environment.
Tate’s SmartAire electronically controlled variable air volume
damper used in conjunction with DirectAire adjusts the amount
of air to meet the specific needs of the rack it services. Sensors
mounted to the front of the rack control the VAV damper
ensuring the proper inlet air temperature is maintained on a rack-
by-rack basis. This flexibility can help effectively cool facilities
implementing virtualization, cloud computing and idle server
shutdown strategies while saving energy.

The Data Center is Rapidly ChangingUnderstanding and Managing Diverse & Variable Loads
The typical data center environment does not contain a single
per rack density level, in fact it would difficult to find any two
racks in a large data center that consume exactly the same
amount of energy. The load diversity results in differing airflow
requirements per rack. Efficient cooling requires that the airflow
delivered to each rack be matched to that rack’s demand.
Each rack in the data center however is a constantly changing
entity, with each add, move or change modifying the load. This
of course changes the rack’s airflow requirements, resulting in
the need to manually adjust the airflow delivered from each panel
to properly and efficiently cool the rack.
To further complicate matters, the load in the rack may change
due to processing demands of the IT hardware at a given time.
This load variability has been driven by IT hardware that has
become more efficient over time, increasing the difference
between idle power consumption, and 100% utilization. This
fact, coupled with the increasing use of cloud computing, will
10
only serve to drive increased load variability in the rack on a
minute by minute basis, making manual tuning of the airflow at
the panel level impossible.
The solution has been to provide sufficient air to accommodate
the peak energy demands of the rack, resulting in wasted
bypass air and over-cooling during all less than peak conditions.
The chart above shows the variability in the energy consumedfor the IT load at the rack level for a Cloud Cluster.

SmartAire Effectively Solves the Problem
SmartAire adapts technologies readily found in
commercial office applications to create a solution for
controlling airflow delivery to the IT racks through the use
of a variable-air-volume (VAV) device installed below each
airflow panel. Each panel & rack tandem can be thought
of as an individual zone. SmartAire measures the incoming
air temperature at the face of the rack and adjusts the
flow to ensure that the temperature at the face of the rack
is never above the maximum allowable set point provided
by the user. When deployed using best practices, the
system is able to virtually eliminate bypass air, and
account for any local temperature fluctuations.

IT load has increased to partial load during the day at
8kW and 960 CFM
SmartAire begins to open the dampers increasing the air-
flow to the rack while decreasing the static pressure under
the floor. The drop in static pressure indicates to the CRAH
unit fans to speed up as they monitor the plenum pressure
sensor to maintain a stable temperature to the rack.
IT load has increased to full load during the day at
14kW and 1680 CFM.
SmartAire fully opens and the CRAH unit fans increase their
speeds to hold a constant underfloor static pressure.
Airflow to the racks is sufficient to keep all temperatures at
the face of the rack at the desired 75˚

Achieve the Ultimate in Financial PerformanceSmartAire Takes Efficiency Even Further
The energy savings component of SmartAire is achieved through
it’s effective management of diversity and variability. Virtualization is
a common server management strategy to increase the computing
power of existing hardware and to save energy. Virtualization
often leads to variability and denser racks with wider ranges in
demand between high utilization and idle states. SmartAire’s
ability to automatically and instantaneously adjust to distribute
exactly the right amount of air needed to cool the equipment
allows the CRAH units variable fan drive to adjust more
accurately for optimum efficiency.
SmartAire also handles load diversity without over-cooling
lower density racks saving energy. Deployed at the rack level
rather than by row, SmartAire can reduce the amount of
airflow to low density racks allowing more airflow to be
delivered to high density areas without increasing underfloor
static pressure or making costly equipment purchases.

PowerAire™
Fan Assisted Airflow to Eliminate Hot Spots
In almost any data center today there is at least one high
density server rack that posses a unique cooling
challenge. Providing enough cooling to satisfy the load of
these few racks often leads to over cooling the other
racks and significantly deteriorates the energy efficiency of
the facility. Finding the balance to ensure proper air flow to
each individual rack, while not wasting energy in over-
cooling is the key to achieving reliability.
Effectively Manage Dense Server Racks & Blades
Tate’s PowerAire fan assist module is designed to provide
a blast of cooling through an individual airflow panel.
Using sensors mounted to the front of the rack the fan will
automatically turn on when conditions require additional
cooling. Equiped with a variable speed fan drive the fan
can be throttled up or down based on the heat load
requirements. This powerful solution is ideal for solving the
toughest hot spots in a data center.
The easy to install PowerAire fan assist is ideal for retrofit
into existing data centers or as part of a new advanced
cooling strategy. PowerAire is an excellent choice for
cooling the most stubborn hot spots
