P recision cooling units with EC fan technology can also offer further savings in running costs. Th


The technology consumes up to 30% less energy than a conventional three-phase fan; precision u nits (such as the Stulz MiniSpace EC range) can also run in energy-saving partial load mode and h ave a high motor efficiency of up to 92%. It is a false economy to prioritise capital outlay when specifying air conditioning units. If you install a solution that is not appropriate f or the technical environment, you will have i ssues. Effectiveness needs to be the primary c onsideration, along with the long-term o perating costs.


Operating features: comfort vs precision I t is important to note that comfort cooling systems also perform ‘oil return cycles’, which override the set temperature controls and can lead to intermittent falls in temperature.


While this is less of a problem in server rooms, t his can present issues in environments such a s laboratories, where precise temperatures are critical to the integrity of the testing processes. Precision cooling units do not need this operating feature and therefore do not present an operational risk.


A dvanced precision cooling units can provide continuous monitoring and control of air filtration to ensure high availability. In the case of the Stulz MiniSpace EC range, an alarm notification can be raised via mobile phone or through the building management system. This helps businesses ensure the resilience and availability of their IT o perations at all times.


Ultimately, rooms subject to high thermal loads need constant climatic conditions in order to work reliably. Fluctuating temperatures, humidity and dust jeopardise both function and data stocks. Precision cooling technology is specifically designed for server rooms and technical


e nvironments where reliable thermal optimisation and high availability are crucial.


With an increase in remote edge data centres and localised server rooms, it will become particularly important to understand the differences between ‘precision’ and ‘comfort’ w hen applying cooling for these systems.


Many specifiers and installers fail to appreciate the impact of employing inappropriate cooling technology until it is too late; there is an urgent need for further education to avoid costly


mistakes and to prevent the risks associated with poor climate control.
