Cooling and Installation Configurations
The requirements for a cooling system vary hugely depending on the location and climate zone. With four basic configurations and many options available, we can offer the right solution for every project requirement in virtually every climate zone.
The special construction with its extremely efficient combination of Free Cooling and evaporative cooling reduces energy costs. The system has been optimized to such an extent that in most regions, 100% mechanical cooling is no longer necessary. pPUE values as low as 1.02 can be achieved.
Dry Mode: At low outside temperatures, hot air from the data center is cooled down by the cold outside air via the plate heat exchanger.
Wet Mode: When the outside temperature is moderate, the outside air is precooled by the adiabatic system before passing through the heat exchanger, where it cools down the air from data center.
Top-Up Mode: At very high outside temperatures, a compressor refrigeration system is used in addition to the adiabatic system to provide top-up cooling.

Redundant cooling configuration for even greater independence
These days, extreme climate conditions characterized by significant temperature fluctuations and hot spells are an ever more frequent occurrence in various regions. If adiabatic cooling is not sufficient, the system has to be combined with a solution that is 100% independent of weather conditions in isolated cases. Liquid cooling systems with chillers and DX heat exchanger systems have proved to be an excellent solution in situations like this.
Our high-performance air handling units are positioned directly on or next to the building. All the necessary chilling components are integrated in the units' housing, saving floor space in the data center and facilitating maintenance, as the service engineers no longer need to enter the data center.
Wall: Installation next to the building
Supply air and exhaust air are routed through the air handling unit horizontally.
The supply air duct can be either connected to an existing raised floor or routed directly into the data center. The return air is fed out of the data center directly into the CyberHandler 2.
This type of installation is particularly suitable for data centers where space is not restricted.
Roof: Installation on the building
The air is conducted through the ceiling of the rooms into the CyberHandler 2. No additional air ducts are needed outdoors for connection. By cleverly locating them on the roof, plus a few minor structural measures, the units can easily be made invisible, which has a dual benefit.
Firstly, units installed on the roof have fewer points of contact with the environment and will always generate less noise pollution. Secondly, data centers are high-security areas, and roof installation makes sabotage more difficult. This kind of installation is especially suitable for data centers in residential and mixed-use areas.
