Wall
Delivering the World’s Most Energy Efficient and Sustainable Thermal Management Solutions
The Air2O Wall minimizes unit footprint with a modular design, with vertical backdraft dampers, intelligent controls, and easy fan access for maintenance. Additional benefits include built-in redundancy - if a fan fails the others fans automatically adjust to maintain the cooling capacity (automatic failover). A significant feature are the aerodynamic coils that improve the efficiency and reduce power consumption. This allows us to provide what we believe to be “the world’s most efficient Fan Array”.

The Air2O Wall is a chilled water fan wall for data centers, built in six standard sizes from 150 to 665 kW. EC fans, vertical backdraft dampers, and the cooling coil form a modular array sized to the cooling load and footprint of each data hall. An optional Eco Tube coil lowers coil air pressure drop and unit power.
150 to 665 kW Nominal Cooling
The Air2O Wall delivers 150 to 665 kW of nominal gross cooling at 20,000 to 90,000 CFM in six standard sizes. For loads or footprints between or beyond the standard sizes, custom sizes are built from the same standard components.
- 150, 225, 300, 450, 600, and 665 kW
- 20,000 to 90,000 CFM airflow
- Custom sizes for project loads and footprints
- Modular array built from standard components
Basis: Nominal gross cooling capacity for the six standard sizes at 98.6°F return air, 75°F supply air, 61°F entering water, and 79°F leaving water. Capacity at the scheduled air and water conditions is confirmed on the design datasheet Air2O issues for each project.
Eco Tube Option Lowers Unit Power
The cooling coil is the largest contributor to internal static pressure drop in a fan wall. The optional Eco Tube coil uses an aerodynamic tube profile that lowers coil air pressure drop by 28% and unit power by 14% compared with a standard tube coil.
- 28% lower coil air pressure drop, Eco Tube
- 14% lower unit power, Eco Tube
- EC fans with integrated speed control
- Optional extended-life filter media
Basis: Eco Tube and standard tube coils compared at 58,100 CFM, equal coil face area, and matched cooling capacity. Coil air pressure drop is 0.83 versus 1.16 in. w.g., and unit power is 18 versus 20.9 kW.
Modular Array, Configured per Project
Module count, fan type, and coil type are configured to the cooling load and the space available in the data hall. Units are built from standard components in a draw-through or blow-through arrangement and use centrifugal or axial EC fans.
- Draw-through or blow-through arrangement
- Centrifugal or axial EC fans
- Standard tube or Eco Tube coil
- MERV 8 or MERV 11 filters
Airflow Control From Data Hall Sensors
A native BACnet DDC controller adjusts fan speed and airflow distribution from temperature, humidity, and pressure sensor inputs, so airflow follows conditions in the data hall as they change. EC fans carry built-in controls for remote monitoring, and the unit connects to the building management system over BACnet or Modbus.
- Native BACnet DDC controller
- BACnet/IP or MS/TP, Modbus TCP or RTU
- Temperature, humidity, and pressure sensing
- Automatic fan speed adjustment
Fan Redundancy and Service Access
If a single fan stops, the remaining fans increase speed to hold airflow, within the array's reserve capacity, and vertical backdraft dampers close against reverse airflow through the idle fan. In the draw-through arrangement, a fan is exchanged from the front once that fan is electrically isolated.
- Automatic compensation on a single fan fault
- Vertical backdraft dampers
- Front fan access, draw-through arrangement
- Rear filter access, draw-through arrangement

Eco Tube Coils
The internal cooling coil is the largest contributor to the internal static pressure and significantly affects overall efficiency. Using Eco Tube provides for a dramatic reduction within the internal pressure drop (up to 50%) resulting in significant energy saving.
Redundancy
Air2O Wall units are designed with built-in redundancy, complemented by smart control systems. If one fan fails, the others automatically take over, maintaining the cooling capacity (Automatic Failover) and minimizing the risk of total system failure. The number of fans is carefully selected to optimize energy efficiency and cooling distribution.
Air2O Wall units can dynamically adjust airflow in real-time based on changing conditions in a data center. Sensors monitor temperature, humidity, and pressure throughout the space, providing continuous feedback to the control system. This allows for automatic adjustments to fan speeds and airflow distribution, ensuring smooth and efficient operation.
