Castrol ON: Our end-to-end service model for liquid cooling, providing assurance for the entire lifecycle through innovative technology..
Castrol ON end-to-end service offering
AI and high-performance computing are reshaping data centres, increasing the need for smarter, more reliable cooling. As power demands rise, liquid-cooling systems are essential – but they can only function to peak potential if cooling fluid is properly maintained.
Castrol ON is our breakthrough end-to-end liquid cooling service model*, providing complete lifecycle assurance through four core components: Start-up, Maintenance, Break/Fix, and Disposal. Powered by innovative technology and an always-on support system, our model helps data centres move confidently into a new era of advanced liquid cooling management.

Fluid thinking, solid solutions
Our end-to-end fluid service model is designed to support the efficient cooling of data centres – with four core service components.
Start up
We build a secure foundation for your cooling system for stable, predictable operation and performance from day one by helping to address initial risks and establishing a scientific performance baseline.
- Pre-installation fluid inspection: Verifying fluid quality on-site before it enters your system.
- System flush and fill: A process for cleaning system internals and assessing system integrity before filling.
- ‘Day 1’ baseline sample: Providing lab analysis to create a memorable 'chemical fingerprint' for future performance tracking.
- Commissioning-phase monitoring: Conducting regular on-site tests during the critical first months of operation.
Maintenance
We support your transition in fluid management from reactive fixes to a proactive, data-driven strategy. Our goal is to help improve system uptime and asset life through actionable intelligence, not just data.
- On-Site Fluid Analysis: Preventive on-site checks performed as part of an additional maintenance service package, helping identify potential issues at an early stage.
- In-Depth Lab Analysis: Comprehensive diagnostics to assess fluid health and identify hidden issues.
- Expert Data Interpretation: Our technical experts translate complex lab reports into clear, actionable insights.
Break/fix
When issues arise, we provide a structured and proactive support framework to help identify and resolve operational challenges. Our specialists work closely with you to assess root causes and implement appropriate corrective actions, in line with agreed service terms.
- Dedicated Telephone Support: A dedicated contact point to coordinate and support the resolution of service-related issues.
- On-Site Support & Corrective Actions: Access to teams for on-site remediation when required.
- Spare Parts Management: Strategic availability of spare parts, fluid and dedicated equipment to handle emergencies.
Disposal
We help manage end-of-life fluids in a responsible way, supporting a safe and compliant transition when fluids need to be replaced.
- Fluid Collection: Providing guidance and coordination for the recovery of used fluid from your facility
- Responsible Disposal: Management of a responsible disposal process.
More innovations, one integrated liquid cooling ecosystem
