Fan Wall Unit
Built for hyperscale.
ENGINEERED WITH INTENTIONALITY
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. Through innovative engineering, our Fan Wall Unit surpasses conventional CRAH technology to deliver exceptional performance that fulfils diverse operational needs.
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.
INTRODUCING OUR FAN WALL UNIT
Designed to excel in mission-critical environments, the Fan Wall unit offers unparalleled cooling capabilities and efficiency for high-density data centres. This innovative solution integrates the principles of modularity and scalability, allowing it to meet diverse client requirements. With a cooling capacity of up to 800kW per unit, it not only delivers exceptional performance but also significantly reduces energy consumption.
Our Fan Wall Unit is an upgrade from conventional CRAH technology, incorporating horizontal airflow technology to optimise circulation and minimise hotspots. Its compact, space-saving design makes it ideal for smaller data centres or facilities requiring high-density configurations. Additionally, maintenance is simplified through rear access to EC fans, ensuring operational continuity with minimal disruption.
From hyperscale data centres to 5G edge facilities, the unit is engineered for adaptability, reliability, and superior cooling performance. Complemented by its compatibility with liquid cooling systems, it is the perfect choice for data centres prioritising efficiency and accessibility.
UNDERSTANDING CRAH
A Computer Room Air Handler (CRAH) is an essential cooling component designed for modern data centres, including those utilising our Fan Wall unit. Unlike traditional air conditioners, a CRAH relies on chilled water from an external chiller system to regulate temperature and humidity effectively.
When integrated with the Fan Wall unit, a CRAH enhances energy efficiency by leveraging variable-speed EC fans and precise airflow management. This synergy ensures uniform temperature distribution across server racks while reducing energy costs and environmental impact.
Ideal for facilities prioritising scalability and redundancy, the combination of Fan Wall unit and CRAH technology provides reliable, consistent cooling tailored to the demands of hyperscale and edge data centres.
How our Fan Wall Unit compares to conventional CRAH
| Aspect | CRAH | Fan Wall Unit (FWU) |
| Capacity | Max capacity of 260kW per unit | Offers up to 800kW per unit |
| Efficiency | Efficiency is lost through upthrow/downthrow airflow | Horizontal airflow increases efficiency |
| Footprint | Not stackable | Stackable, increasing density |
| TCO | Higher energy usage and maintenance requirements typically result in higher TCO | Lower power consumption, reduced maintenance costs, and modular scalability contribute to lower TCO over time |
