Precision Air Conditioning

STULZ the natural choice
Precise, Reliable and Innovative
Air Conditioning for Information and
Communication Technology
Perfect
Air Conditioning for
Secure ICT Technology
2
Innovative blade constructions, multi-core processors and UMTS are
continuously improving the performance of modern ICT technology.
However, as performance increases so do thermal loads and air conditioning requirements, along with operators’ concerns about the operating reliability and availability of their infrastructure. State of the art
precision air conditioning technology from STULZ removes these
concerns, as it provides maximum reliability for your information and
telecommunications equipment.
The entire range can be installed individually
STULZ precision air conditioning units include circulating air systems,
cold water systems and high-density racks. Through their diverse designs
and dimensions, they can provide the perfect customized solution for
your requirements – combining flexible use, the ideal configuration and
tried and tested reliability. Find out more and choose precision air conditioning from STULZ.

The Perfect Solution for Any Situation
In general, a distinction is made between comfort and precision air conditioning. While comfort
air conditioning creates a pleasant environment for people, precision air conditioning technology
provides reliable cooling that is geared towards the requirements of technical infrastructure.
Dedicated technology rooms in data centres or switching stations require precisely controlled
relative humidity, room temperature, air conduction and air distribution. Precision air conditioning
units from STULZ enable you to create precisely defined climatic conditions – with pinpoint
accuracy and outstanding reliability.
Latent or Sensible Cooling
The sensible part of the
cooling capacity reduces the
temperature, while the latent
part dehumidifies the air.
Comfort air conditioning units
can use up to 50 % of their
energy for dehumidification,
whereas precision units convert more than 95 % of the
energy used exclusively into
cooling capacity. The technology required to achieve
this pays off quickly in terms
of lower operating costs.
Air Distribution, Heat
Dissipation and Filtration
Precision air conditioning
units from STULZ filter and
circulate three times the
amount of air as comfort
units with the same rated
capacity. They reliably dissipate isolated thermal loads
even from distant corners of
the room, while continuously
monitoring and precisely
controlling the temperature
and air filtration.
Controlled Temperatures
Information and communication technology only works
reliably and without faults
within a relatively narrow
temperature range.

Controlled Humidity
Unlike comfort air conditioning units, precision units
feature strictly controlled and
accurate dehumidification
(tolerance +/- 5% relative
humidity), as too much humidity can lead to condensation
and corrosion, while too
little can cause static charges,
data loss and damage to
hardware.
Precise humidity control
Excellent Reliability
Comfort air conditioning
units mainly operate in
summer and only for a few
hours each day. By contrast,
precision units need to
be available whenever the
electronic equipment to be
cooled is in operation.
This is normally the case for
24 hours a day, 365 days
a year.
This is why STULZ makes
such high demands on the
quality of their precision
air conditioning units and is
able to offer high availability
systems with 99.999% reliability.

Circulating Air
A Breath of Fresh Air for
Sensitive Technology
Most precision air conditioning systems for IT, telecommunications and technology rooms are circulating air systems
designed specifically for the individual thermal loads that
occur. The more technology is installed in a room and the
greater the waste heat from the hardware, the more care is
required in planning and designing the air distribution.
STULZ precision air conditioning units enable you to base
your planning on maximum reliability – regardless of whether
the performance requirements are simple or complex.
MiniSpace
If you need precise, reliable and economical air conditioning
for small technology and server rooms, the MiniSpace series
provides a space-saving, microprocessor controlled solution.

Maximum Performance for a
Reliable Infrastructure
With the development of its CyberAir precision air conditioning series, STULZ is setting new
standards in energy efficiency, compact design and serviceability. If you want cutting-edge
air conditioning technology and to cut your operating costs, put your trust in CyberAir’s
innovative EC fan technology and new control concepts.
12% Less Space
For a cooling capacity of 42 kW, a CyberAir
precision air conditioning unit requires an
installation area of just 1 m2.
Central Control and
Monitoring of Modular Systems
State of the art control engineering means
that up to 31 CyberAir precision air conditioning units can be combined into a single
network and integrated into central building
services systems. This gives you full control
of your air conditioning at all times.
Up To 60% Less Energy
In contrast to conventional technology,
CyberAir precision air conditioning units
incorporate state of the art EC fan technology and feature a free cooling option.
This cuts energy costs by up to 60%.
5 dB(A) Less Noise
Noise-absorbing materials that meet the
Öko-Tex 100 standard, ingenious fan configuration and smooth, optimal air path reduce
the noise emissions from CyberAir precision
air conditioning units by more than 5 dB(A).

High-Density
Reliable Dissipation of
Isolated Thermal Loads
Modern server technologies have higher performance but take up less and
less space. This can lead to high thermal loads at isolated points, which are
difficult to eliminate with conventional air conditioning technology. This is
why STULZ CyberChill server racks are directly cooled with water. This enables
thermal loads of up to 35 kW per rack to be reliably dissipated. They can
either be added to existing data centres or utilised as a stand-alone solution.
10
CyberChill Water Cooling, When Air is Not Enough
If the thermal loads in server racks exceed 5 kW, conventional
air conditioning systems cannot deliver sufficient air.
CyberChill uses a recirculation air cooling circuit to cool the
servers, removing the intense local heat load by means of an
air to water exchanger.
11
Water
Cold Water Systems –
Efficient and Reliable
Water is the most efficient medium for heat
transfer. This is why water is increasingly
being used to cool technical equipment in
ICT and medical technology. Demand control
concepts and free cooling options ensure
that energy consumption is low. This enables
you to cut your operating costs and reduce
the burden on the environment.

CyberCool CSO and CLO Outdoor Chillers:
Outdoor Installation for Demanding Jobs
CyberCool Outdoor Chiller units are cold
water systems that use speed controlled fans,
timed controllers and low-noise, highly efficient scroll compressors to achieve excellent
energy efficiency and quiet operation.
An optional controller is available that automatically selects “Free cooling”, “Mixed mode”
and “Compressor cooling”, reducing energy
consumption by up to 40 % compared to
conventional controllers.
In addition to the CyberCool CSO, the noise
reduced CyberCool CLO design is available.
This unit provides the same options but
operates at a noise level around 10 dB(A)
lower, making it ideal for use in areas that
are sensitive to noise.
CyberCool Indoor Data Chiller:
Cooling Water with Minimal Space
With their compact design, CyberCool Indoor
Data Chillers produce enough cooling water
for a cooling capacity of up to 100 kW and
yet require an area of just 0.89 m2. They fit
through standard doors or and lifts, can be
combined on a modular basis into redundant
systems with 99.999 % reliability and can
be installed in areas of buildings that are sensitive to noise.

CyberCool Pump&Transfer:

Connecting high-density racks to the central
cold water supply requires hydraulic separation
to minimise the water quantity, pressure and
risk of leaks in sensitive IT areas. CyberCool
Pump&Transfer provides this separation and,
as a twin circuit system, allows a redundant
cold water supply to be set up.
