Conventional Airflow Wall (Fan Wall)
The airflow wall is a high-efficiency, energy-saving cooling solution designed for medium to large data centers. The unit uses chilled water (optional refrigerant or dual-cooling source) for cooling. The chilled water version supports high water temperatures, and during cold seasons can work with the main chiller to achieve free cooling, extending the annual utilization of natural cooling sources and enabling precise temperature and humidity control. Ideal for high static pressure, high cooling capacity, and long air delivery distance scenarios, conventional airflow walls provide cooling capacities ranging from 150 to 350 kW. The cooling system design is closely integrated with the data center infrastructure, leveraging the building structure for long-distance supply and return air delivery without raised flooring, resulting in improved cooling performance.
PRODUCT FEATURES:
◆ Extra-large, low-resistance coil design supports higher water temperatures and reduces energy consumption.
◆ Matrix-style air wall airflow with horizontal supply ensures uniform temperature distribution and reduces turbulence.
◆ Enclosed airflow channels maintain stable cold aisles, enabling even supply air temperature.
◆ Modular design for control and fan drive units, supporting hot-swappable modules for faster maintenance.
◆ Quick deployment without raised floors, reducing cooling system costs by up to 10%.
◆ Easy and efficient maintenance: single-side access design allows maintenance from one side.
