Modern data centers host thousands of servers. All this processing power produces an immense amount of heat, heat that must be dissipated in high-performance heat exchangers. Such a situation must be avoided because it can lead to downtime, limited performance, or even permanent damage to equipment in extreme cases.
The cooling system represents a significant part of a data center’s energy consumption. Evaporative cooling towers offer an efficient solution to reduce this consumption, thus contributing to lowering the PUE (Power Usage Effectiveness) index and operating costs. Studies show that evaporative cooling systems can reduce energy consumption by 30–50% or even more, if implemented correctly.
In practice, this translates to significant savings on electricity bills and a reduced facility carbon footprint. For example, instead of operating the cooling compressors at maximum load 24/7, a data center with an efficient heat transfer system for chiller condensation can transfer a large part of the heat dissipation load to these towers, which use only fans and pumps, consuming much less specific energy for each MW of dissipated heat.
The principle is simple: installing a system of water- or glycol-cooled chillers, together with cooling towers, is much more efficient than using only air-cooled chillers.
Why EWK cooling towers are the optimal choice for data centers?
- High energy efficiency. EWK towers, with FRP (fiberglass reinforced polyester) casing and high-efficiency fans, drastically reduce energy consumption. Thanks to their construction and design, a large thermal transfer capacity is obtained with minimal specific energy consumption.
- Reliability and durability. Robust construction, corrosion-resistant materials and a pre-assembled modular structure ensure a long service life and reduced maintenance. This is vital for data centers, where downtime can generate major losses.
- Flexibility and scalability. EWK offers modular solutions for any context: compact models (EWK 225) or large units (EWK 900/1260/1800) that can easily adapt to data center expansions or new projects.
- Corrosion control and hygiene. The use of non-corrosive materials and the possibility of integrating water treatment systems (biocide dosing, pH measurement) prevents deposits and bacterial contamination, while also helping to maintain optimal temperature and performance.
- Low noise. EWK models, such as the EWK-D, are built with silent fans and insulated casings, representing a suitable choice for data centers located in urban environments or in areas with decibel limits imposed by law or demographic context.
Walhalla – a data center managed with the help of EWK cooling towers
The “Walhalla” data center, recognized as one of the most secure IT centers in Europe, located in the Science Park of Jaume I University in Castellon, chose EWK solutions for the cooling of its critical infrastructure. Two EWK 1800 cooling towers were installed, ensuring efficient and continuous cooling for IT equipment.
