Data Centers

Data centers are under increasing pressure

Data centers are under increasing pressure to deliver ever more computing power, while space, energy, and water needs must remain limited. With the rise of AI workloads, cloud computing, and high-performance computing (HPC), power density per server rack is increasing sharply. Cooling systems must therefore remove more heat, while energy and water consumption need to come down. Without the right technology, this can lead to a higher Power Usage Effectiveness (PUE), a less optimal Water Usage Effectiveness (WUE), or even unplanned downtime of critical systems. Especially in mission-critical environments, where every minute of downtime is costly, every degree of cooling efficiency counts.

Spraybest supports data centers and related infrastructure with spray technology for adiabatic cooling, liquid cooling, and air cooling. We think along with you about the right spray and misting technology for your cooling system. We work with the renowned brand BETE, which is used worldwide in mission-critical environments where continuity and efficiency come first. BETE's wide range of standard nozzles, combined with custom solutions and engineering support, helps data centers maintain optimal conditions, meet environmental requirements, support infrastructure upgrades, and perform reliably with minimal downtime, whether it concerns an existing facility or a new hyperscale data center under construction.

Adiabatic cooling for more efficient data center cooling

Adiabatic cooling is one of the most widely used spray techniques for improving the performance of air-cooled heat exchangers in modern data centers. By pre-cooling the air entering condensers and heat exchangers with fine, controlled misting, the inlet air temperature is lowered. This reduces the load on chillers, lowers fan energy consumption, and limits peak power demand precisely when it's needed most, for example during hot summer days when the ambient temperature is already high.

BETE supplies nozzles designed to produce very fine droplets, so that the water fully evaporates before coming into contact with equipment. This is essential to prevent damage, corrosion, or unwanted deposits. Especially in the high ambient temperatures often found in AI and hyperscale data centers, adiabatic cooling contributes to more stable heat removal and better performance of the cooling installation, without the need for heavy electric chillers. Because the required investment is relatively modest compared to the energy savings achieved, adiabatic cooling often pays for itself within a short time, and the technology directly contributes to a lower PUE for your facility.

Liquid cooling for high-density environments

As power density per rack increases, liquid cooling becomes an increasingly important part of the cooling strategy in data centers. Whether it concerns direct-to-chip cooling, immersion cooling, or hybrid setups, even water distribution in cooling towers and heat exchangers is essential for fast and uniform heat transfer. Insufficient distribution can lead to localized overheating, lower efficiency, or extra wear on installation components, which over time puts pressure on the reliability of the entire cooling chain.

BETE supplies nozzles that ensure even distribution of water across the entire surface of the cooling tower or heat exchanger. This improves the efficiency and reliability of both closed and open evaporative cooling systems, which is of great importance in high-density server environments where downtime is simply not an option. By choosing the right spray technology, liquid cooling can be precisely tailored to the specific heat load of your data center, even when that load varies significantly by zone or by rack. This keeps the entire closed-loop or evaporative cooling system performing stably, even under sharply fluctuating computing loads throughout the day.

Air cooling and inlet cooling

Spray technology also plays an important role within air-cooled data center infrastructure. By pre-cooling the inlet air with evaporative cooling, the thermal performance of existing air handling systems can be improved without requiring major changes to the infrastructure. This helps lower energy consumption and stabilize temperatures, even in high-density server and AI computing environments where heat generation can rise quickly and where traditional HVAC systems reach their limits.

BETE offers spray solutions that can be easily integrated with existing HVAC systems, allowing inlet cooling and evaporative support to be applied as a supplementary measure. This way, air cooling can be optimized without major retrofits, contributing to a faster payback and a more flexible cooling strategy. This allows existing data centers to extend the lifespan of current cooling installations, while new-build projects benefit from a compact and energy-efficient addition to their HVAC design.

Additional applications in and around the data center

Besides the direct cooling of servers and equipment, spray technology also plays a role in the broader infrastructure surrounding data centers, such as water treatment, environmental technology, and on-site power generation. Think of aeration and air stripping in water purification, gas scrubbing and gas cooling for local power generation or emergency power supplies, liquid distribution over packed columns, or tank mixing to keep liquids homogeneous in storage tanks. Spray technology can also play a role in reducing NOx emissions from any emergency generators.

For all these applications, BETE supplies nozzles tailored to the specific process conditions, so that the supporting systems around your data center also continue to function reliably. This creates a complete solution that not only cools the server room itself, but also supports the entire surrounding technical infrastructure, from water treatment to local power generation.
