As artificial intelligence (AI), machine learning, and high-performance computing workloads surge, data centers are being pushed to new limits. At Sabey Data Centers, we’re committed to leading this transformation, especially when it comes to sustainable, scalable, and reliable cooling solutions.
Today’s high-density server racks routinely exceed 30kW, and projections suggest that by 2027, some will surpass 100kW per rack. Traditional air-cooling systems increasingly struggle to efficiently manage the heat generated by these next-generation workloads. Even under optimal conditions, air-cooling systems typically cap out at 50 kW per rack, leaving a widening gap between what’s needed and what’s possible. In the face of this challenge, liquid cooling has emerged as an ideal solution for modern, high-density data centers.
Benefits of Liquid Cooling
Liquid cooling has several key advantages. The technology provides direct contact with heat-generating components, dissipating heat more efficiently and maintaining optimal operating temperatures even at extreme densities. By reducing reliance on energy-intensive fans and large-scale HVAC systems, it significantly improves Power Usage Effectiveness (PUE) and lowers overall energy consumption. Plus, as AI and other high-density workloads grow, liquid cooling supports rack densities up to 200kW, without the need for proportional increases in floor space or mechanical infrastructure.
Due to its enhanced energy efficiency, liquid cooling means a smaller carbon footprint, making it an appealing choice as companies increasingly work to reach sustainability goals. Additionally, these systems can enable heat reuse for district heating or industrial processes, aligning with ambitious ESG and net-zero commitments.
Types of Liquid Cooling
Three primary liquid cooling approaches are driving the transformation in data center thermal management:
Rear-Door Heat Exchangers (RDHx):
Mounted on the back of racks, these water-cooled panels capture and remove heat directly from exhaust air, offering a straightforward upgrade path for many existing facilities.
Direct-to-Chip Cooling:
Coolant is delivered right to the hottest components, CPUs and GPUs, via cold plates, ensuring maximum heat transfer efficiency.
Immersion Cooling:
Servers are submerged in non-conductive liquid, allowing for unparalleled heat absorption and the highest rack densities.
Sabey Data Centers: Looking Ahead
Innovation in cooling is essential to support our customers’ most demanding workloads, now and in the future. Our partnership with a growing list of leading liquid cooling technology providers, such as JetCool Technologies, underscores our commitment to delivering cutting-edge, sustainable solutions for our tenants. We are actively integrating liquid cooling into our new and existing campuses, ensuring that our infrastructure remains future-ready and environmentally responsible.
The future of data center cooling is clear: as workloads intensify and sustainability becomes non-negotiable, liquid cooling will be the standard for high-density environments. At Sabey, we’re not just embracing this future, we’re building it, campus by campus, rack by rack.
