Powering performance: data centre cooling applications
Experience maximum uptime and optimal performance
For 50 years, Belimo has provided quality, reliable field devices for the energy-efficient control of heating, ventilation, and air-conditioning systems. Our expertise, scalable applications, and position as a global market leader have led to our success in providing data centre cooling applications, where reliability and quality are of utmost importance.
We offer actuators, valves, sensors, and meters that are designed to ensure uninterrupted performance, optimal flow, standalone systems, and energy efficiency.
The data centre landscape is evolving, with newer GPUs requiring more heat rejection than ever before. Hot and cold aisle containment strategies cannot reject sufficient heat for high density racks. Belimo is ready with innovative data centre cooling technologies, facilitating more efficient liquid cooling systems that provide enhanced thermal conductivity and reduced energy consumption.
Belimo products in data centre applications
-
Belimo application
Butterfly valves with high performance actuators for large flow rates.Central plants supply chilled water to the entire data centre. Due to the significant cooling requirements of modern data centres, this process demands high flow rates and, consequently, large-sized valves. Belimo butterfly valves, equipped with high-performance actuators, are perfectly suited for this application, thanks to their high close-off pressure, minimal leakage, and IP66-rated housings (equivalent to NEMA 4), ensuring reliable operation even in demanding conditions.

Belimo application
Electronic pressure-independent valves (EPIVs) and sensors.Computer room air handling units (CRAHs) supply conditioned air to the white space within data centres. Belimo's electronic pressure-independent valves (EPIVs) are key components in CRAH systems, delivering precise and reliable control of water flow. These valves play a vital role in maintaining optimal temperature and air humidity conditions within mission-critical environments.

Belimo application
Damper actuators (EF and GK) on large damper bank.Belimo damper actuators are vital components in fan wall systems, providing precise airflow control to servers located within the white space. Characterised control valves (CCVs) and electronic pressure-independent valves (EPIVs) manage water flow through the coils, ensuring efficient cooling and maintaining the required supply air temperatures. Working in unison, these Belimo applications are essential for sustaining optimal environmental conditions for sensitive IT infrastructures.

Belimo application
Belimo Energy Valves (EVs) and differential pressure sensors for precise flow control in high- performance computing.Direct-to-chip liquid cooling, commonly known as cold plate technology, is one of the most widely used methods for cooling servers with high thermal output, such as those utilised in high-performance computing (HPC), artificial intelligence (AI), and machine learning (ML) applications. The Belimo Energy Valve™ is ideally suited for this application, as it maintains a constant differential pressure across the rack. This ensures precise flow to each cold plate, even in scenarios where a server is taken offline for maintenance.
-
Belimo application
Belimo Energy Valves (EVs), characterised control valves (CCVs), and electronic pressure-independent valves (EPIVs).Cooling distribution units (CDUs) supply chilled-water or water-glycol mixtures to cool heat-generating equipment such as servers. Belimo offers a comprehensive portfolio of characterised control valves (CCVs), electronic pressure-independent valves (EPIVs), and Energy Valves that are ideally suited for use in CDUs. These valves ensure precise flow control and can be easily adapted as your cooling demands evolve.

Belimo application
Electronic pressure-independent valves (EPIVs) and characterised control valves (CCVs) for accurate flow control.Accurate flow control is essential for the efficient operation of rear-door heat exchangers (RDHx). Belimo's electronic pressure-independent valves (EPIVs) and characterised control valves (CCVs) provide reliable and precise flow control, ensuring optimal performance of your RDHx system.
-
Belimo application
Electronic pressure-independent valves (EPIVs) for precise flow control and Energy Valves (EVs) for monitoring.Two-phase immersion cooling systems require precise water flow to ensure effective condensation of the dielectric fluid. Belimo's electronic pressure-independent valves (EPIVs) maintain consistent flow to the coil, even where there are system pressure fluctuations. The Belimo Energy Valve™ continuously monitors supply and return water temperatures, calculates thermal energy, and delivers valuable insights to help track cooling performance and detect inefficiencies.
-
Belimo application
Fail-safe actuators for combustion air control.Generators provide backup power to ensure continuous server operation during a mains power failure. Belimo fail-safe actuators are the ideal application for controlling the precise amount of combustion air required by these generators. The fail-safe ensures that airflow can be shut off immediately in the event of a fault. IP-rated options, such as IP66 (equivalent to NEMA 4), are available for installations located outside the generator housing.
-
Belimo application
Fire and smoke actuators for safety and protection.Belimo fire and smoke actuators are essential safety devices designed to protect data centres from fire and smoke hazards. These damper actuators are integrated into fire and smoke detection systems and are responsible for controlling various mechanical components to mitigate the spread of fire and smoke during an emergency.
