Precision solutions for cooling and air conditioning
Cooling systems conduct waste heat away from the data centre and ensure that the IT systems run at an optimum operating temperature range of 18 to 27 °C and a humidity range of 40 to 60%. As a rule, they consist of air-conditioning units in the computer rooms and the sub-systems, which are required for their operation; for example refrigerating machines, re-cooling towers, condensers, pumps, pipelines, distribution networks as well as components of the regulation and control circuits down to the rack level.
The cooling and air conditioning systems in modern data centres must be redundantly designed in both capacity component and distribution path to meet the requirements of highly available systems. We place particular value on energy-efficient cooling concepts which represent the power usage efficiency (PUE) of the total data centre.
Our cooling solutions are precisely designed to meet these requirements and are based on innovative technologies, offering you the highest efficiency and power with minimum long-term operating costs. With our complete solutions, you have available a comprehensive cooling portfolio for the specific requirements of IT platforms in your business-critical server rooms and data centre sites – from limited requirements through to those of high-performance platforms.
We use only reliable precision equipment for the computer room air conditioning (CRAC, CRAH): closed control units (CCUs) as well as open row coolers and closed side coolers which ensure cooling power according to demand and precise cold air guidance.
Among the features of our CCUs are their high reliability and their customer and project specific design as regards the necessary technology, power, redundancy and expandability.
Our portfolio of the open row coolers and closed side coolers includes solutions with many different redundancy and power options, depending on whether they are used in open rack rows in which targeted individual high-density zones or racks must be supplied with higher cooling power, or whether they are incorporated in cold air or warm air passages where mixing of the airflows and resultant cooling losses must be avoided.
In addition there are complete solutions for energy-efficient cold and/or hot isle containment as well as built-in raised floor cooling panels and innovative floor panel technologies for an intelligent regulation of cold air.
Each of our precision solutions integrates seamlessly into the cooling concept chosen by you, whether it is free, geothermic or solar cooling, with or without raised floor, and with chilled water (CHW) or with gas (direct expansion, DX).
