The validation followed a technical review covering corrosion resistance, thermal stability, dilution-water quality and propylene glycol base-fluid purity.
The assessment also examined compatibility with wetted materials, including the metals, plastics, seals and other components that come into contact with fluid inside a liquid-cooling system.
Castrol’s business and global supply-chain resilience were also considered as part of the wider review, reflecting the requirements of AI infrastructure deployments operating across multiple markets.
“We evaluate every thermal management fluid under rigorous test conditions before it reaches the market,” says Sung A. Kim, Data Centre Global Technology Manager at Castrol.
