Immersion Cooling Systems for Data Centres

Benefits of Immersion Cooling List

• Efficiency: Immersion cooling significantly increases cooling efficiency by allowing direct contact between the hardware and the cooling fluid, enabling much faster heat dissipation compared to traditional air cooling.

• Energy Consumption: Eliminating the need for air cooling and fans, this technology reduces energy consumption by up to 30%, which will lead to lower energy costs.

• Carbon Footprint: Since 95% of a server's carbon footprint comes from its energy usage, reducing energy consumption at the server level helps our customers lower their overall carbon footprint.

• Reliability: Equipment lifespan is extended due to more stable and lower operating temperatures, which decreases the likelihood of overheating and system failures.

• Maintenance: Compared to air-cooled servers, maintenance requirements are significantly reduced, as there are no moving parts like fans that can wear out or fail. The only maintenance required is a fluid replacement every 10 years.

• Space Efficiency: Higher densities in data centres enables more efficient space utilization. We can fit three chassis with a total of twelve cassettes (servers) in a standard 42U rack. Each cassette can cool up to 4kW of hardware, resulting in a total of 48kW per rack.

• Noise and Vibration: The design of the product eliminates noise and vibrations from fans, creating a quieter working environment.

• Retrofit Capabilities: The HRM4 can be deployed in both new and existing data centres. The solution can be installed on a raised floor and integrated within a rack, alongside air-cooled systems, such as three chassis combined with storage and switches above.

• Power Usage Effectiveness (PUE): HRM4 requires less cooling within the data centre, as only a dry cooler is needed — no chillers or CRAC units are required. This results in a lower PUE of 1.04. Cost savings can be shared between the operator and the customer.

• Temperature: The system can operate with an inlet temperature of up to 40°C and deliver a return water temperature of 60°C. This allows the warm water, typically directed to chillers, to be used for cooling the HRM4 system. The higher return temperature also enables better utilization of waste heat, such as for the expanding potential for district heating.

Workloads List

• VMware/KVM (Hypervisors): These virtualization platforms require significant processing power and can benefit from the efficient cooling provided by immersion.

• Database Servers: High performance and reliability are critical for database management, especially with intensive transaction processing and storage management.

• Compute-Heavy HPC Workloads: Heavy computational tasks, such as scientific simulations and numerical analysis, generate significant heat, which can be efficiently managed with immersion cooling.

• Telecoms: In this sector, reliable and efficient cooling is crucial for maintaining network equipment and communication servers.

• Big Data Analytics: Processing large volumes of data requires powerful servers that operate intensively, resulting in substantial heat production.
