Data centre and IT cooling products
Castrol ON liquid cooling fluids are re-defining the future of data centres.
Data Centre Cooling
Fluid is the smartest surrounding for the most advanced technologies – first the brain, now data centres.
The rapid growth of AI, cloud computing, and high-performance workloads means traditional air cooling systems are struggling to keep pace with data centre infrastructure – consuming significant energy and water, and restricting performance potential.
Liquid cooling represents the next evolution in thermal management. A smarter, more efficient approach to remove heat directly from critical components – reducing energy use, improving reliability, and enabling higher compute density.
Together with our customers and partners, we’re shaping a future where technology, efficiency, and sustainability go hand in hand – fueling the progress of tomorrow.

Our strategic partnerships allow us to ensure compatibility, performance confidence, and end-to-end support for your cooling strategy.
Together, we are driving the development of thermal management solutions to accelerate innovation in data centres.
Direct-to-Chip cooling circulates a liquid through cold plates that sit directly on heat-generating components, rapidly removing heat at the source. This approach is ideal for high-performance servers or targeted hotspots.
Immersion cooling submerges entire components or servers in dielectric fluid, offering uniform heat removal, excellent electrical insulation, and high thermal stability. Immersion cooling is particularly effective for energy-intensive workloads.
