Stulz Computer Room Air Conditioning (CRAC) CyberAiR Room Cooling Solution
The CyberAiR 2 precision air-conditioning system
with DFC conditions the air in large computer and equipment rooms
with a heat load of over 20 kilowatts up to 60 % more economically
than conventional compressor cooling systems.
CyberAiR 2 is the world’s first precision
air-conditioning system that considers heat load in computer rooms
and seasonally varying ambient temperatures. It automatically
selects the optimal operation mode for each case. In cool weather,
the optional DFC automatic air-conditioning technology makes use of
thrifty dynamic free cooling with outside air. Energy-intensive
compressor cooling (DX) is only switched on when absolutely
necessary. For this purpose, all units are equipped with
speed-controlled EC fans and electronic expansion valves.
In addition to the DFC version described above,
STULZ also offers the CyberAiR 2 series in the versions A, G, GE,
ACW, GCW, CW and CW2. CyberAiR 2 units are available in six sizes.
They require floor space 1000 mm to 2900 mm wide and only 890 mm
deep. And the planner has a choice of three coolants - R407C, R410A
or R134a.

|
Control by microprocessor
|
Each unit has its own electronic
controller. The C7000 microprocessor
controls all active components.
|
|
Seven cooling systems
|
From a choice of seven cooling
systems, data center operators will
find the optimum balance between
investment, running costs, and
energy efficiency. All systems are
available as both up-flow and
down-flow versions.
|
|
Save space and energy
|
Units are produced both as a
space-saving standard version and an
energy-optimized low-energy version
|
|
Three different refrigerants
|
In addition to water as the
cooling medium, the devices can run
with three different refrigerants
R407C, R410A, and high temperature
refrigerant R134a.
