Summary
- The Uniflair XCA range includes air-cooled and free-cooling chillers for high-density AI data centre loads.
- Units cover six sizes from around 1,200kW to 2,500kW and use oil-free magnetic-bearing centrifugal compressors.
- The launch reflects rising demand for chilled-water systems that can support liquid cooling, elevated water temperatures, and lower maintenance risk.
Schneider Electric has launched its Uniflair XCA chiller line for high-density AI data centres, adding air-cooled and free-cooling systems designed to support liquid-cooled environments and variable thermal loads.
The range includes the Uniflair XCAC air-cooled series and the Uniflair XCAF free-cooling series. Schneider said the platform uses oil-free centrifugal compressors with magnetic-bearing technology and built-in variable-speed drives, supported by a high-efficiency spray-type evaporator.
The XCA line includes six unit sizes, with cooling capacities ranging from around 1,200kW to 2,500kW. Schneider said the systems are designed to operate across elevated water temperatures, use low-GWP refrigerants, and reduce maintenance, contamination risk, and mechanical losses by removing oil from the compressor design.
The company is addressing the mechanical plant gap created by GPU clusters and liquid-cooled halls. As rack densities rise, operators have to reassess chilled-water temperatures, heat rejection, controls, water use, and the redundancy needed to run dense AI workloads reliably.
AI changes the chiller brief
The cooling challenge created by AI is often described at rack level, but much of the cost and resilience pressure sits outside the rack. Direct-to-chip and rear-door systems still need heat rejection, pumping, controls, filtration, and plant that can maintain stable conditions across changing workloads. Chillers have to support higher heat loads without undermining energy performance or creating new maintenance exposure.
Elevated water temperatures are one of the main design shifts. Liquid cooling can allow warmer water loops than traditional chilled-air environments, improving chiller efficiency and widening the periods when free cooling is available in suitable climates. That advantage only appears when the whole system is coherent: server liquid loops, facility water systems, CDUs, heat exchangers, controls, and external plant all need to match.
Oil-free magnetic-bearing compressors address a different operational concern. Mechanical losses, lubricant management, and contamination risk become more material when plant is operating at high utilisation and serving revenue-critical AI loads. Lower maintenance does not remove the need for disciplined operations, but it can reduce one class of failure and service complexity.
The launch lands in a market where retrofit is becoming as important as new build. European operators with existing power allocations may find that upgrading cooling plant is a faster route to AI-ready capacity than securing a new campus, new grid connection, and new planning consent. Chiller selection will be part of that calculation, particularly where facilities need to move from lower-density air-cooled halls to mixed or liquid-cooled deployments.
Schneider’s broader data centre portfolio spans power, cooling, racks, automation, and digital systems. The XCA launch strengthens the mechanical side of that offer as AI design pulls power and cooling suppliers closer together. The most competitive systems will be judged on efficiency, but also on buildability, maintainability, water strategy, heat-reuse potential, and the electrical realities of dense compute.
