Stulz Computer Room Air Conditioning (CRAC) CyberRow Row-based Cooling Solution
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.
