Castrol cooling fluids validated by NVIDIA
Analysis based on 13 articles · First reported Jul 20, 2026 · Last updated Aug 18, 2026
The validation is expected to boost demand for BP — Castrol's liquid cooling fluids, positively impacting BP's specialty chemicals segment and supporting Nvidia's AI infrastructure ecosystem. It may also influence the broader data centre cooling market, encouraging adoption of direct-to-chip cooling solutions.
BP — Castrol, a subsidiary of BP, announced that its direct-to-chip cooling fluids, BP — Castrol ON PG25 and PG25T, have been validated by Nvidia for use in AI factory and data centre infrastructure. The validation followed a technical review covering corrosion resistance, thermal stability, dilution-water quality, propylene glycol base-fluid purity, and compatibility with wetted materials, as well as BP — Castrol's business and global supply-chain resilience. This milestone strengthens BP — Castrol's position in liquid cooling as AI drives demand for more powerful, higher-density data centres. The fluids are designed for closed-loop systems that circulate coolant through cold plates attached to CPUs and GPUs, improving water usage effectiveness. The validation provides data centre operators, equipment manufacturers, and cooling-system providers with additional confidence in selecting these fluids for high-performance AI infrastructure.
