High-density integrated container racks with immersion liquid cooling are available in stock

High-density liquid-cooled racks, including immersion cooling solutions, are commercially available and designed for AI, HPC, and high-density data center deployments.

Overview of Immersion and Liquid-Cooled Racks

High-density integrated racks with immersion liquid cooling submerge servers in thermally conductive dielectric fluids, maximizing heat transfer and energy efficiency while eliminating the need for traditional air cooling . These systems are ideal for workloads with extreme power density, such as GPU-intensive AI clusters, where a single rack can consume up to 80 kW or more . Immersion cooling is the most energy-efficient form of liquid cooling, reducing reliance on fans and improving space utilization .

Key Features and Benefits

• Direct-to-Chip Cooling: Cold plates or two-phase evaporators are mounted directly on CPUs, GPUs, and DIMMs, removing 70–75% of heat at the component level .
• High Rack Density: Supports multiple GPUs or processors per rack, significantly increasing compute capacity within the same footprint .
• Energy Efficiency: Reduces power usage effectiveness (PUE) and operational costs by up to 40% compared to air-cooled systems .
• Scalability: Modular designs allow deployment of single or multi-rack solutions, with coolant distribution units (CDUs) providing capacities from 100 kW to over 2.5 MW .
• Integration: Can be deployed in existing air-cooled facilities or purpose-built liquid-only data centers, with options for hybrid air-liquid configurations .

Leading Providers

• Schneider Electric: Offers end-to-end liquid cooling, including the ChilledDoor® Rack Cooling System for 75 kW per rack and MCDU-70 units for scalable AI deployments .
• Vertiv: Provides immersion and direct-to-chip cooling options, suitable for retrofitting air-cooled facilities or building liquid-only data centers .
• Supermicro: Delivers rack-scale liquid cooling with in-rack or in-row CDUs, supporting up to 1.8 MW per row and high-density GPU deployments .
• DCX: Offers centralized and in-rack CDUs for HPC and AI workloads, with capacities from 600 kW to 2.6 MW, simplifying large-scale liquid cooling infrastructure .
• AHEAD: Specializes in integrated air- and liquid-cooled rack solutions, including direct-to-chip immersion-ready racks, with custom multi-rack deployments for AI/HPC workloads .

Deployment Considerations

• Infrastructure Requirements: Immersion cooling may require specialized containment, dielectric fluids, and heat rejection systems. Direct-to-chip solutions integrate more easily into existing facilities .
• Maintenance and Reliability: Redundant CDUs, hot-swappable pumps, and centralized coolant loops enhance uptime and reduce operational risk .
• Cost and ROI: While immersion cooling has higher upfront costs, it offers rapid ROI through energy savings, higher density, and reduced cooling complexity .

Conclusion

High-density integrated container racks with immersion liquid cooling are available from multiple vendors and are optimized for AI, HPC, and high-density data center environments. They provide superior thermal management, energy efficiency, and scalability compared to traditional air-cooled racks. For real-time stock availability, it is recommended to contact vendors directly, as inventory may vary based on configuration and regional supply.
