Stulz to Release CyberRow In Row Cooling Units
Stulz announced it has begun manufacturing In Row server cooling units under the name "CyberRow".
Stulz, a German-headquartered company with 400 engineering, sales and manufacturing employees in the United States, will release the North American version of its CyberRow in row server cooling unit in the coming weeks. Stulz manufactures a wide range of cooling products: CRAC & CRAH units, Ultrasonic Humidification, Dehumidification units and Chillers.
Stulz's entry into the in row cooling unit market means it will be joining the ranks of other industry giants: Liebert, APC and Rittal.
The Stulz CyberRow will come in a Chilled Water (CW) and Direct Expansion (DX) version. The CW version will be available in two widths: 12" and 24". The DX CyberRow will be available in a 12" version only.
No clones here
The first thing you notice about the Stulz CyberRow is its optional "side air discharge" feature, which directs the cold air sideways, directly across the face of the server cabinets, where it is easily pulled in by the servers' fans. Stulz claims this is a unique feature, that their competition only discharges the air straight out into the aisle. Stulz claims this uique side discharge option increases efficiency.
The Stulz CyberRow uses EC Plenum fans, offering highly efficient and variable speed airflow.
Another feature seen on the DX version is the use of a variable speed compressor made by Mitsubishi. The variable speed compressor is different from Copeland's digital scroll compressor in that the speed of the compressor itself is varied, which helps maintain flow rate. The variable speed compressor fond on the DX CyberRow allows the unit's output to be modulated based on changing load conditions. Capacity modulation in the Chilled Water units is accomplished using a 600 p.s.i. modulating control valve.
The Stulz CyberRow will have several design schemes. It is able to control fan speed, chilled water valve % open (or compressor speed in DX units) based on Return Air temperature, Supply Air temperature, and fans based on Static Pressure sensors.
It looks as cool as it feels
The CyberRow comes standard from the factory in Frederick, Maryland, with Stulz's charcoal grey color and a textured "orange peel" finish. There is an off-white color option as well, and Stulz says they would consider other colors if a customer requests it.
The new Stulz CyberRow in row cooling models are good fits for small and medium businesses, legacy data centers that need additional cooling in a localized pattern, and facilities with no raised floor to serve as a supply air plenum.
With a cooling capacity of up to 73kW, the Stulz CyberRow in row cooler is an efficient, scalable option for IT managers.
