Why Precision Cooling Is Key to Data Centre Performance

As digital infrastructure grows, so does the need to house high-density, heat-generating environments especially data centres (DCs). Andrew Elliott, Precision Cooling Specialist at Panasonic Heating & Cooling Solutions, explains why traditional cooling systems are falling short and how Panasonic’s innovations are providing the solution.

Cooling in Critical Environments

With cloud capabilities expanding, more of our data is stored virtually. This rapid growth demands greater performance and efficiency, particularly in AI-driven DCs that require advanced cooling to maintain optimal conditions and protect equipment.

Why Comfort Cooling Isn’t Enough

Traditional comfort cooling systems, typically split-type units using DX pipework, are designed for intermittent use and operate within a wide temperature range (±3°C). They’re not built for the continuous, precise demands of DCs, often leading to system fatigue and inconsistent temperatures.

Close Control: Precision, Flexibility and Customisable

Close control systems, such as Panasonic’s range, are designed to run continuously (8,760 hours/year), maintain tighter temperature tolerances (±1°C), and offer humidity control. This level of precision not only reduces fluctuations in operational cost but helps reduce thermal stress and extend equipment lifespan.

Panasonic’s range of precision cooling solutions are incredibly customisable and can be tailored to suit different critical spaces, these include:

• P Series: Compact, perimeter-mounted
• R Series: In-row units for airflow direct to server
• G Series: High cooling capacity, underfloor installations
• W Series: Cold wall units for technical corridors

All these units support BMS integration for smart monitoring.

Clean Air and Consistent Circulation

Airborne contaminants can damage microcircuits, so Panasonic’s systems include high-grade filtration. They also ensure consistent air recirculation, preventing hot spots and supporting heat densities over 1000W/m², far beyond the 50W/m² typical of comfort cooling.

Built for Reliability

With regular maintenance, such as quarterly inspections and filter replacements, close control units maintain resilience and minimise downtime.

Conclusion

Panasonic’s precision cooling solutions offer reliable, adaptable performance for the evolving demands of data centres. With tighter environmental control, superior filtration, and 24/7 operation, they support both equipment longevity and sustainability goals.
