STULZ offers next-gen data centre
climate control with CyberWall
intelligent POWER AND COOLING
STULZ, one of the world’s leading
providers of energy efficient
temperature and humidity
management technology for missioncritical
data centre applications,
has announced the availability of its
CyberWall cooling solution. Designed
for operators of large, colocation and
hyperscale data centres, it comprises a
range of precision air conditioning units
specifically developed for facilities with
separate aisles. Its horizontal airflow
technology enables reliable operation of
high IT load densities, without the use of
raised floors or side coolers.
Heat density within racks is increasing
with each new generation of data centre
equipment, which is also extremely
sensitive and must operate within a strict
temperature range. Data centre operators
that fail to combat this increase in heat
load, risk causing significant harm to their
IT equipment, reducing its operational life,
lowering performance and reliability, and
increasing energy expenditure.
In order to protect equipment and offer
unrivalled levels of cooling performance,
CyberWall is configured around highperformance
fan walls comprising
cutting-edge electronically commutated
(EC) fans with integrated air/water
heat exchangers. This allows a cooling
capacity of around 100kW per metre of
wall length to be achieved and means
that the efficient air conditioning of high
power densities, as well as racks of 42U
or more, is now possible.
With data centre white space now at a
premium, STULZ has designed CyberWall
so that indoor air handlers with cold water

connection can be mounted in rows or
stacked without gaps – making use of
all available wall space and optimising
system performance. Mounted at the
aisle end, where they supply individual
rack rows horizontally with cold air, the
warm aisle is separated by a containment
system with a ceiling duct, so that
reliable separation of cold and warm air
is guaranteed. The CyberWall system
also fits precisely into the existing service
corridor, which allows the maintenance of
air conditioners to be completed without
the need for personnel to enter the
server area.
STULZ CyberWall modules achieve an
impressive cooling capacity of 220kW,
with 16°C water inlet and an airflow rate
of 55,000m³/h per air conditioning unit.
As part of its pioneering Custom Indoor
Air Handling Unit (AHU) series, STULZ
provides a wide range of output sizes
and special designs, offering customers
a comprehensive portfolio of unit
dimensions, components and capacities
to meet specific requirements.
The combination of CyberWall and
the Custom Indoor AHU series means
that operators have access to a highperformance
cooling solution, which takes
into account ASHRAE specifications and
achieves impressive partial Power Usage
Effectiveness (pPUE) values.
“Climate management is one of the key
challenges faced by operators of large,
colocation and hyperscale data centres,”
said Tobias Wolf, Deputy Head of Product
Management at STULZ. “A failure to
understand the consequences of heat
generation and deal with it properly can
be disastrous. With CyberWall, STULZ
has used its extensive research and
development capabilities to develop
a genuine game changer in effective
air conditioning, allowing operators to
protect their technology investments and
maximise uptime.” ◊
