Perfect Air Conditioning forSecure ICT Technology

3

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 con-

ditioning requirements, along with operators’ concerns about the ope-

rating 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 condi-

tioning from STULZ.

Precise temperature control

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 con-

vert more than 95 % of the

energy used exclusively into

cooling capacity. The tech-

nology 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 dissi-

pate 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 communi-

cation technology only works

reliably and without faults

within a relatively narrow

temperature range.

STULZ precision air condi-

tioning units ensure optimum

temperature accuracy with

maximum tolerances of

+/- 1 °C, while comfort units

can normally deviate from

the set value by as much as

+/- 3 °C.

Optimum air distribution and filtrationwith precision air conditioning

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.

Comfort air conditioning unit:Capacity 100 m3/h per kW

Precise humidity control Excellent reliabilitywith 24 hrs/day continuous load

Controlled Humidity

Unlike comfort air condition-

ing units, precision units

feature strictly controlled and

accurate dehumidification

(tolerance +/- 5% relative

humidity), as too much humi-

dity can lead to condensation

and corrosion, while too

little can cause static charges,

data loss and damage to

hardware.

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% reli-

ability.

Most precision air conditioning systems for IT, telecommuni-

cations 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.

Mounted in the false floor, the AirBooster

conveys up to 1,200 m3/h of cold air directly

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.

Maximum Performance for aReliable Infrastructure

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 condi-

tioning 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 tech-

nology 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 configu-

ration and smooth, optimal air path reduce

the noise emissions from CyberAir precision

air conditioning units by more than 5 dB(A).

10

High-Density

Reliable Dissipation ofIsolated 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.

11

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.

12

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 JobsCyberCool Outdoor Chiller units are cold

water systems that use speed controlled fans,

timed controllers and low-noise, highly effi-

cient scroll compressors to achieve excellent

energy efficiency and quiet operation.

An optional controller is available that auto-

matically 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 SpaceWith 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 sen-

sitive to noise.

CyberCool Pump&Transfer:Compact System SeparationConnecting 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.
