Cooling supply

Always keeping the correct temperature

Creating the optimal climatic conditions in your data center can be challenging without appropriate cooling and heating concepts. Severe temperature deviations above or below the normal range, not only affect the service life of sensitive equipment, but also increase the risk of failure due to possible overheating. Which configuration is most efficient for you depends on various factors such as structural and spatial conditions and ambient temperature at your location.

Cooling supply

With water-cooled server systems, a lot of energy can be dissipated directly to the cold water via a heat sink of the chips. This way of cooling is very economical, because the indirect free cooling without compression cooling can be used even at high outside temperatures. Recirculating air cooling units, sidecoolers or fan coil units cool the air in server and technical rooms to the desired levels.

Hot water cooling enables the efficient use of waste heat for a wide range of applications, such as heating buildings. This technology is ideal for implementing sustainable energy concepts.

Warm water cooling is a cost-effective and environmentally friendly solution that enables a higher return temperature and thus contributes to improved waste heat utilization.

The 2-phase cooling uses the change between liquid and gaseous state for particularly efficient heat dissipation. This technology is ideal for racks with very high power density and demanding IT applications.

These systems ensure that IT hardware is sufficiently cooled at all times and at all outside temperatures. Refrigeration systems generate cold water, which at certain outside temperatures can be produced in indirect free cooling even without the compressors contained in the cooling systems.

Refrigerants are being compressed by the compressors, then again evaporated and thereby generate cold. This cold is used for the cooling process. Ammonia, carbon dioxide and water, as well as hydrocarbons and air, are also called natural refrigerants, in opposition to halogenated hydrocarbons.

In this type of climate conditioning, the energy required for cooling the servers is limited to fans installed in the data center. The air circulating in the cooling system is cooled down and directed to the consuming units. In addition, air filters provide support to maintain the quality of the circulating air.

Achieve optimal temperature conditions in your data center with containment systems for cold or warm aisles. A distinction is made between Contained Cold Aisle (CCA) and Contained Hot Aisle (CHA). By strictly separating the two temperature zones, the necessary air conditioning can be supplied to the server room in a precise and targeted way, thus reducing energy costs. The use of aisle containment is subject to certain structural and spatial requirements. Therefore, the solution may be more or less suitable for your data center.
