KMT Service: Flexim ultrasonic non-invasive flowmeter helps a data center in Germany meet EED requirements

The faster modern technologies are advancing, the bigger data centers need to be. As servers increase in density, the structures they are housed in are becoming one of the biggest sources of energy consumption in the industry, due to the large amount of heat they release needing to be reliably mitigated at a continuous rate. This is why the largest operator of data centers relies on modern cooling systems with high energy efficiency during the expansion of one of their sites in Germany. This is achieved with a combination of different methods for cooling and effective usage of energy, and the quantity of cooling water is measured with ultrasound technology Flexim, now an Emerson brand. Why this is necessary, KMT Service, a partner of Flexim, explained to BalkanEngineer.com.

"Keeping in mind the density of modern data centers, even short-term temperature deviations from optimal values ​​can lead to damage to the equipment, unplanned shutdowns and notable financial losses. This forces operators of these facilities to place a strong emphasis on the reliability and efficiency of the cooling infrastructure, as well as on precise performance monitoring, which can guarantee operational continuity and full use of energy," commented KMT Service.

This is the reason a leading company, which is in charge of data centers, built such as highly efficient and optimized cooling system for one of its locations in Germany, including passive and active cooling based on seasonal conditions. During the cold months passive cooling is utilized, relying on the low temperature of the outside atmosphere. The technical solution is based on heat exchangers and dry coolers. During the warmer months, when the outside temperature is high, chillers are used “to help”, working on a request mode, meaning being used only when necessary. Back to winter, a heat pump was chosen for heating the office premises, which uses the heat of the cooling water from the servers, thus achieving minimal additional energy use.
