Data Center Cooling Solutions, with Dry Cooler

Dry coolers are energy-efficient and water-saving cooling solutions for data centers, ideal for regions with moderate climates. They work by using ambient air to cool the refrigerant or cooling water directly, eliminating the need for constant water evaporation like in traditional cooling towers.

Core Advantages of Dry Coolers in Data Centers

Water Conservation: They do not rely on evaporative cooling, reducing water consumption by over 90% compared to cooling towers. This is critical for data centers in water-scarce areas.

Energy Efficiency: In low to moderate ambient temperatures (typically below 25°C), dry coolers can operate without mechanical refrigeration, directly using outdoor air to meet cooling demands and cutting PUE (Power Usage Effectiveness).

Low Maintenance: Fewer components (no water circulation systems or chemical treatment for water) mean lower maintenance costs and reduced risk of scale buildup or corrosion.

Environmental Friendliness: No water discharge or chemical additives (e.g., biocides for cooling towers) minimizes environmental impact, aligning with green data center standards.

Key Application Scenarios

Moderate Climate Zones: Regions with annual average temperatures below 20°C (e.g., Northern Europe, parts of North America) can maximize dry cooler usage, even achieving "free cooling" for long periods.

Hybrid Cooling Systems: Combined with chillers, dry coolers act as a primary cooling source when ambient air is cool enough. Chillers only activate during high-temperature periods, balancing efficiency and reliability.

Edge Data Centers: Smaller edge facilities with limited space and water access benefit from dry coolers’ compact design and low operational complexity.
