Castrol ON Direct Liquid Cooling PG 25 is specifically engineered for direct-to-chip cooling applications in data centres.
Castrol has announced the launch of Castrol ON Direct Liquid Cooling PG 25, a new propylene glycol-based cooling fluid specifically designed for direct-to-chip cooling applications in high-performance data centres.
The ready-to-use solution helps meet the complex thermal management needs of today’s high-performance computing, while offering protection against corrosion and bacterial growth.
Castrol ON PG 25 has been developed to meet the rapidly growing adoption of direct-to-chip cooling technology in data centres, driven by the demand for higher computing densities, particularly for applications like AI, Machine Learning and high-performance computing. The global data centre cooling market is expected to reach USD16.8 billion by 2028, with direct-to-chip cooling becoming widely adopted.
Traditional air cooling, which currently dominates data centre cooling, often cannot efficiently manage the heat generated by densely packed, high-power servers.
To address these escalating cooling demands, the industry is turning to more efficient solutions like direct-to-chip cooling which delivers liquid coolant directly to heat-generating components, enabling faster heat transfer and reducing the reliance on energy-intensive air conditioning systems.
This approach helps maintain the optimal operating temperatures crucial for system reliability and performance.
“As data centres continue to push the boundaries of computing power, direct-to-chip cooling offers an opportunity for data centres to manage the increasing thermal demands of next-generation processors,” said Peter Huang, Global Vice President of Thermal Management, Castrol. “Through the launch of PG 25, we are combining Castrol’s expertise in thermal management with our global capabilities to help customers meet their cooling challenges with efficiency.”
Castrol’s new PG 25 fluid offers several key advantages for data centre operators:
• Non-toxic propylene glycol formulation for enhanced safety in sensitive computing environments
• Extended protection against metal corrosion and bacterial growth
• Comprehensive compatibility with common cooling system materials
• Ready-to-use 25% concentration requiring no dilution
• Global availability backed by Castrol’s technical support network
Castrol ON Direct Liquid Cooling PG 25 is supported by the company’s comprehensive operational support and monitoring solutions, enabling data centre operators to optimise the performance of their cooling systems throughout their lifecycle.
“Through research and collaboration with our customers and technology partners, we’ve developed a truly end-to-end solution that supports data centres to rapidly implement and benefit from direct-to-chip cooling technologies while anticipating the future needs of the industry,” added Sung A Kim, Global Head of Technology for Data Centre Liquid Solutions, Castrol. “Further, our global network will enable us to provide comprehensive support all the way from initial testing to deployment, supporting our customers to confidently implement direct-to-chip cooling solutions across their facilities.”
With the addition of Castrol ON Direct Liquid Cooling PG 25 to Castrol’s existing range of immersion cooling fluids and associated services, Castrol can be a one-stop partner for meeting the liquid cooling solutions of today and tomorrow.
