How Schneider is Preparing Data Centres for AI Heat Loads

The AI boom is transforming the data centre industry, but not in the way many expected.

While much of the attention is fixed on ever-more-powerful GPUs and hyperscale AI campuses, another battle is unfolding behind the scenes, which is the challenge of removing unprecedented amounts of heat.

As rack densities climb and liquid cooling moves into the mainstream, thermal management is becoming one of the most important pieces of data centre infrastructure.

The ability to cool high-performance computing environments efficiently is now directly linked to capacity, operational costs and reliability.

It is against this backdrop that Schneider Electric has launched its new Uniflair XCA chiller platform, designed to help operators manage the growing cooling demands of AI workloads while balancing energy efficiency and sustainability goals.

Cooling takes centre stage

AI workloads are changing the design assumptions that have underpinned data centres for years.

Higher rack densities and the growing adoption of liquid cooling architectures are increasing the demands placed on cooling systems, making thermal management a critical part of facility operations.

Schneider's response is the new Uniflair XCAC air-cooled and Uniflair XCAF free-cooling chillers.

Designed for high-density liquid-cooled environments, the systems combine oil-free centrifugal compressors with magnetic bearing technology and integrated variable-speed drives.

The platform is available in six sizes ranging from 1,200kW to 2,500kW and has been engineered to operate across a broad range of thermal loads and environmental conditions.

Andrew Bradner, Senior Vice President, Cooling Business at Schneider Electric, says: "Energy efficiency, adaptability and reliability are essential components of liquid cooling systems for AI-optimized data centres, and we've designed the Uniflair XCA line with these most important design features at the forefront.

"With adaptable water operating temperatures and versatile deployment options, the XCA line features a system-level approach that gives operators scalability, enhanced performance and long-term peace of mind as data center complexity continues to rise."

Focusing on efficiency

As energy costs continue to rise, efficiency is one of the most important metrics for data centre operators.

Schneider says the new platform has been developed to improve performance across multiple areas of the cooling process.

At the core of the system are oil-free magnetic bearing centrifugal compressors, which remove the need for lubrication systems.

According to Schneider, this reduces maintenance requirements and contamination risks while delivering efficiency gains of up to 25%.

The chillers also feature a heat-exchange architecture that combines spray evaporator technology with V-shaped microchannel coils.

The design is intended to improve thermal performance while reducing refrigerant volumes and overall material usage.

Meanwhile, a redesigned heat-rejection architecture uses V-shaped coils and a new generation of large-diameter EC fans to increase airflow and maintain stable operation during periods of high ambient temperature.

Extending free cooling opportunities

One of the most significant features of the XCAF models is their ability to maximise free cooling.

Designed to operate in temperatures ranging from -20°C to +52°C, the systems support water outlet temperatures of up to 33°C.

Schneider says that in moderate climates, operators could achieve energy savings of up to 60% compared with relying exclusively on mechanical cooling.

The company believes this can help facilities reduce energy consumption while extending the periods during which free cooling can be used throughout the year.

The systems can also be configured with a wide range of electrical, hydraulic, acoustic and performance options, allowing operators to tailor deployments to specific site requirements.

Bringing software into cooling operations

Alongside the hardware improvements, Schneider is adding a greater degree of software intelligence to cooling operations.

The platform includes variable-speed pump algorithms that can operate based on constant flow, temperature differential or head pressure requirements.

Fan controls can also be adjusted according to temperature, load conditions or scheduled operating periods, including low-noise and ultra-low-noise modes.

Additional monitoring capabilities include integrated energy metering and real-time water flow measurement, providing operators with greater visibility into system performance.

The company says these software-driven features can help improve stability, reduce compressor cycling and optimise cooling efficiency in real time.

For mission-critical environments, the platform also includes a quick restart capability designed to restore full operating capacity within three minutes of a power outage.

Schneider has also designed the platform around sustainability requirements, using ultra-low-GWP refrigerants and aligning the system with the EU F-Gas Regulation 2024/573.

The first Uniflair XCA units are scheduled to begin shipping globally in June 2026.
