Operators have the following key challenges regarding the cooling of data-centres and server-rooms:

  • High availability and operating safety
  • Increasing electricity prices
  • F-Gas Regulation
  • Global warming
  • Successive build-up of the thermal loads
  • Structural guidelines relating to environmental, fire and water protection, sound pollution etc.

With the eChiller: en route to PUE = 1

Data centre efficiency is measured in terms of power usage effectiveness (PUE). The PUE value is calculated as the coefficient of the data centre’s overall energy consumption and the energy actually used by the IT equipment in the server racks. While a PUE of 1.0 would be ideal, a value of above 2.0 is widespread, meaning that the same amount of energy is consumed for cooling and other processes as for the computing equipment itself. A contributory factor for a high PUE can be inefficient cooling.

The eChiller offers the following benefits for cooling data centres and server rooms

  • High efficiency due to fully adjustable, integrated free cooling
  • Exempted from F-Gas Regulation
  • Highly available refrigerant: water
  • High availability due to few moving parts
  • Fully visualisable refrigeration circuit via remote monitoring (link: monitoring)
  • Predictive maintenance & service (link to predictive maintenance and service)

Cooling capacity that can grow with your data centre

Another major advantage of using the eChiller at your data centre is its flexible adaptability to increasing cooling capacity. The installation at the German bank server room of Sparkassen Calw demonstrates the eChiller’s outstanding energy efficiency, even at part load, and its adaptability to gradually increasing cooling capacity: the load of the eChiller when first taken into operation at this facility was lelow 20 per cent, but steadily increased to full load as the server capacity increased.
