Fan Wall Unit
Built for hyperscale.
INTRODUCING OUR FAN WALL UNIT
Built with intensive operations in mind, our Fan Wall Unit solution is a scalable, modular system for hyperscale data centres. With almost two decades of precision cooling experience, we engineered the most important principles into our solution: efficiency and accessibility.
EFFICIENCY AT ITS PEAK
Each Fan Wall unit delivers up to 800kW of cooling, providing unparalleled performance while also reducing overall energy consumption. Perfect for high-density environments where scalability and redundancy are key requirements.
Evolution of cooling.
ENGINEERED WITH INTENTIONALITY
Through innovative engineering, our Fan Wall Unit surpasses conventional CRAH technology to deliver exceptional performance that fulfils diverse operational needs. Our FWU utilizes horizontal airflow to reduce resistance faced by traditional upflow or downthrow configurations, increasing efficiency and reducing hotspots.
ASPECT | CRAH | FAN WALL UNIT |
CAPACITY | Max capacity of 260kW per unit. | Offers up to 800kW per unit. |
EFFICIENCY | Up/downthrow airflow is less efficient. | Horizontal airflow increases efficiency. |
FOOTPRINT | Not stackable. | Stackable, increasing density. |
TCO | Higher energy usage and maintenance requirements, alongside more complex integration, typically result in higher TCO. | Lower consumption, reduced maintenance costs, and modular scalability contribute to lower TCO over time. |


OPTIMISED AIRFLOW Unique horizontal airflow technology reduces hotspots via uniform circulation. |
