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.
Features & Benefits
FEATURES
BENEFITS
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.

CyberAiR 2 LowNoise DX and GE Units, single-circuit
CyberRow is an advanced precision A/C unit, which is tailor-made for the targeted cooling of racks. In the CyberRow, innovative air conduction has been enhanced by state-of-the-art technology, which enhances the performance, flexibility and efficiency. Fluctuating server rack loads, space restrictions, lack of a raised floor, existing server technology – these are some of the tricky situations in everyday practice that the CyberRow has been specially developed to deal with.
CyberRow is a standalone A/C unit and is installed and operated independently from the rack. This complete separation of the rack and the A/C unit increases reliability and provides greater freedom for designing the layout in the data centre.
CyberRow is available with 2 sizes and 4 different cooling systems:
CW-System (chilled water cooling)
A-System (direct expansion)
G-System (direct expansion and plate condenser)
GE-System (direct expansion with indirect free cooling)

Features & Benefits
FEATURES
BENEFITS
Horizontal air conduction
The cold air reaches the rack via the shortest route
Electronic control
Monitors and controls all components inside and outside the A/C unit that are needed to generate cold air
3 EC fans
Independent, infinitely adjustable EC fans ensure maximum efficiency
EC compressor
Infinitely adjustable for precise cooling capacity and 50% lower power consumption when starting the compressor, thanks to soft start function
Electronic expansion value
Finely controls the cooling capacity within a few seconds
Flexibility and compatibility
The CyberRow is available in 4 different cooling systems (A, CW, G, and as a GE system with Indirect Fee Cooling) and in 2 sizes
Modernizing cooling systems in existing buildings
Thanks to its compact size and universal suitability for racks from different manufacturers, the CyberRow can also be used without need to modernize cooling system in existing buildings

CyberRow with Variable Capacity Control
Efficient IT plant runs 24/7, but the operational conditions in a Data Center can change throughout the day. The CyberRow rack-coolers monitor and adapt the cooling capacity to the local heat load. This avoids the under or over supply of cooling in a particular area.
All over the world, air-conditioning systems made by STULZ are keeping sensitive information and communication technology cool. In data centers and mobile phone stations, they ensure maximum availability with minimum energy consumption. Moreover, STULZ precision air-conditioning systems and chillers are employed in industrial production and medicine, too.
