FläktGroup has produced its first 2.5 MW refrigerant-based cooling distribution unit (CDU) for a U.S. customer, according to a report by Cooling Post. The project’s first phase is designed for a 25 MW data hall, with a second phase planned to expand capacity to 50 MW; the wider campus is planned for 200 MW across eight phases.
FläktGroup has produced its first 2.5 MW cooling distribution unit (CDU), a refrigerant-based system made at the company’s Arkansas facility for a customer in the United States. The unit is intended for a data center project whose first phase is designed to serve a 25 MW data hall, according to Cooling Post.
The unit is a direct-expansion (DX), refrigerant-based CDU, rather than a conventional liquid-to-liquid system. Cooling Post reported that FläktGroup developed it in close collaboration with the customer to meet the project’s specific requirements. The report describes this as the company’s first CDU at the 2.5 MW capacity; it does not provide technical specifications beyond the cooling technology and rating.
The project is planned in stages. Its first phase is designed for a 25 MW data hall, while a second phase is expected to double that capacity to 50 MW. Those figures describe the planned data-hall capacity, not the output of the single 2.5 MW CDU. The development is part of a wider campus with 200 MW of total planned power capacity across eight phases.
FläktGroup executive vice-president for Data Centres Americas Marc Hayes said the project reflects the company’s effort to respond to changing cooling needs as data center operators adopt liquid cooling for AI applications. That is the company’s characterization of the market and project; the report does not identify the customer, provide a delivery date or describe the system’s operating results.
A New Cooling Option for Large Data Halls
The announcement adds a 2.5 MW refrigerant-based CDU to FläktGroup’s reported data center cooling work at a time when operators are considering liquid cooling for high-density computing, including AI workloads. A CDU supports the transfer and management of heat from server-side liquid cooling systems. The technology and capacity of the equipment can matter as facilities plan how to cool large halls, but the source report does not provide performance data that would allow comparisons with other systems.
The project’s planned scale also gives the production milestone a broader setting: a 25 MW first-phase hall is expected to form part of a campus planned for 200 MW across eight phases. The CDU’s stated 2.5 MW rating should not be read as the total cooling provision for the hall or campus. The source does not say how many units will be installed or how the system will be integrated with other cooling equipment.

How the Project Is Planned to Scale
Cooling Post reported that FläktGroup engineered the unit at its Arkansas facility for a U.S. customer. The equipment uses refrigerant-based cooling, distinguishing it from conventional liquid-to-liquid CDUs, which use a liquid circuit to transfer heat between systems. The report provides no further details on refrigerant type, system architecture or the design conditions for this project.
The project’s published capacity figures describe different scopes. The new CDU is rated at 2.5 MW; the initial data hall is planned for 25 MW; the second phase is intended to bring data-hall capacity to 50 MW; and the wider campus is planned for 200 MW across eight development phases. The report does not specify the schedule for those phases or whether all campus capacity has been committed.
“As the industry increasingly adopts liquid cooling to support AI applications, this project demonstrates our ability to develop innovative solutions that address emerging customer challenges while strengthening our position in the rapidly evolving data centre cooling market.”

Delivery, Performance and Deployment Details
The available report does not name the U.S. customer or say when the CDU will be delivered, installed or commissioned. It also does not give test results, efficiency figures, operating conditions, refrigerant details, pricing or warranty information. The unit’s production is reported, but its performance in a live data center is not described.
It is also unclear how many CDUs the project will require, whether this 2.5 MW unit is intended for the first phase alone, and how the cooling system will scale as the data hall and campus expand. The 25 MW, 50 MW and 200 MW figures are presented as planned capacities; the report does not provide construction or completion dates for the phases.
Installation and Campus Phases Ahead
The next reported milestone would be delivery and deployment of the CDU at the customer’s site, followed by information about its commissioning and operation. FläktGroup and the customer have not provided a timetable in the source report, so the date of installation and any performance assessment remain unknown.
For the wider project, the stated plan is to move from a 25 MW first-phase data hall toward 50 MW in a second phase, within a campus planned for 200 MW over eight phases. Those are project plans rather than confirmed completed capacity. Updates on construction, equipment orders and phase timing would clarify how the campus is progressing.
Key Questions
What has FläktGroup produced?
FläktGroup has produced its first reported 2.5 MW DX CDU for a U.S. customer. The unit uses refrigerant-based cooling and was made at the company’s Arkansas facility.
What does CDU mean in this announcement?
CDU stands for cooling distribution unit. It is equipment used in liquid-cooling systems to manage heat transfer between the data center’s cooling infrastructure and server-side circuits.
How does the CDU’s rating relate to the data hall?
The CDU is rated at 2.5 MW, while the project’s first data hall is planned for 25 MW. The source does not state how many CDUs will be installed or how the 2.5 MW unit fits into the full cooling design.
How large is the planned data center campus?
The wider campus is planned for 200 MW of total power capacity across eight development phases. The source does not give a timetable for completing those phases.
When will the CDU be installed and operating?
No delivery, installation or commissioning date was reported. The announcement confirms production, but does not establish when the equipment will enter service.
