Castrol Announces Cooling Fluids Approved for AI Data Centers by NVIDIA
In a significant advance for the cooling fluid industry, Castrol has announced the validation of its Castrol ON PG25 and PG25T fluids for direct chip cooling, specifically tailored for AI factories and data centers compliant with NVIDIA's stringent performance standards.
This validation ensures that operators managing data centers, equipment manufacturers, and cooling system suppliers can confidently select Castrol's solutions for high-performance AI infrastructure. As artificial intelligence and high-performance computing accelerate, data centers face increasing processing demands that generate substantial heat—challenges that traditional air cooling systems struggle to address alone. Castrol's direct chip cooling approach involves circulating a specialized fluid through cooling plates that attach to vital components like CPUs and GPUs. By doing so, the cooling is more efficient and systemic, allowing for improved heat management necessary for today's powerful computing tasks.
Designed as a closed-loop system, Castrol ON PG25 continuously circulates the coolant, reducing exposure to atmospheric conditions which in turn minimizes water evaporation losses. This design not only enhances cooling efficiency but also significantly optimizes water usage within AI factories, addressing growing concerns over resource sustainability.
The successful validation process included a comprehensive technical assessment that checked for corrosion resistance, thermal stability, dilution water quality, purity of the propylene glycol-based fluid, and compatibility with materials in contact with the coolant—encompassing metals, plastics, seals, and other components in liquid cooling systems. This rigorous analysis also explored Castrol's operational resilience and global supply chain efficiency, ensuring reliability under demanding conditions.
Peter Huang, Global President of Castrol's Thermal Management and Data Centers division, emphasized the industry's evolving needs, stating, "As AI infrastructures expand, the sector requires cooling solutions that are efficient, easy to deploy, and reliably durable over the long term. The integration of our fluids into NVIDIA-validated AI factory infrastructure reassures clients not just about the performance but also Castrol's commitment to provide seamless global support across markets. This marks a significant step in making liquid cooling a dependable element of AI factory design and operations."
Sung A. Kim, Global Head of Data Center Technologies at Castrol, noted, "Our assessment process for each thermal management fluid adheres to rigorous testing conditions prior to market release. The validation granted by NVIDIA verifies that the PG25 (OAT) and PG25T (IAT) fluids meet these standards, even under the increased scale and intensity of contemporary AI infrastructures."
