Focus on: Cooling Energy & Environmental Management targeted testing. This scenario reflects a wider industry challenge: cooling already accounts for 30–40 per cent of total data centre electricity use, leaving little room for unnoticed losses. To address this, the facility could implement a proactive fluid management strategy centred on routine sampling, laboratory analysis and trend-based diagnostics to identify early signs of degradation, contamination or inhibitor depletion before performance is affected. Pairing this approach with carefully specified thermal fluids supports stable heat transfer and consistent flow characteristics across high-density cooling loops. Selecting fluids based on properties including thermal conductivity, freeze protection and material compatibility helps optimise pump efficiency, stabilise PUE and reduce the likelihood of thermal stress or unplanned outages. When integrated with heat recovery, for example by redirecting higher-grade waste heat to nearby low-temperature heating networks, this approach can further improve overall energy utilisation while strengthening operational resilience and supporting ESG targets. Designing for resilience, not reaction While illustrative, this example reflects a reality many operators now face. Data centres are no longer static facilities — they are evolving, highintensity environments where thermal performance directly influences cost, carbon footprint and continuity of service. Predictive, data-led maintenance is increasingly recognised as a core operational discipline. In fact, predictive maintenance is one of the most effective ways digital technologies can reduce energy waste across the value chain and thermal fluid management is no exception. As global data creation accelerates — forecast to approach 400 zettabytes (ZB) by 2028, according to industry estimates — the margin for inefficiency continues to shrink. Cooling strategy can no longer sit quietly in the background. For data centre operators, the message is clear: proactive cooling and fluid management turn a hidden operational risk into a controllable, strategic asset. In an industry defined by uptime, trust and sustainability, that shift may prove just as critical as the next generation of servers themselves.
