Overview
AquaRack immerses servers directly in electrically non-conductive cooling fluid for uniform, reliable heat removal. It significantly reduces cooling power consumption while maintaining performance in high-density GPU and CPU deployments. By reducing data center space requirements and noise, AquaRack lowers the total cost of ownership and supports ESG goals.
Why AquaRack
Energy Efficiency
Reduce cooling power consumption by up to 90% (based on cooling load).
Space Efficiency and Optimized Maintenance
Support high-density cooling of up to 50 kW per 21U rack.
Enhanced Reliability and Durability
Maintain stable cooling performance even under heavy GPU and CPU workloads.
Advancing ESG Through Sustainable Cooling
Reduce energy consumption and CO₂ emissions by 30–50%.
Lower Maintenance Costs
Prevent dust and moisture ingress to reduce server failures.
Server Waste Heat Recovery for a Circular Energy Economy
Recover server waste heat for heating and other secondary uses.
