FläktGroup has produced its first 2.5 MW direct-expansion (DX) cooling distribution unit for a customer in the United States. The project’s first phase is designed for a 25 MW data hall, with a second phase planned to double that capacity; the wider campus is planned for 200 MW across eight phases.
FläktGroup says it has produced its first 2.5 MW direct-expansion cooling distribution unit (DX CDU) for a customer in the United States, marking a new product deployment aimed at data-centre liquid cooling. The refrigerant-based unit was built at the company’s Arkansas facility and is intended for a project whose first phase is designed to serve a 25 MW data hall.
The company says the CDU was engineered by a specialist team for modern data-centre applications and developed in close collaboration with the customer to meet project requirements. FläktGroup describes the equipment as a refrigerant-based system, distinguishing it from conventional liquid-to-liquid CDU designs. The source does not provide detailed technical specifications or explain how the unit will be integrated with the site’s cooling infrastructure.
The customer project is planned in stages. Its first phase is designed for a 25 MW data hall, and a second phase is intended to double the data hall’s capacity to 50 MW. The wider campus is planned to reach 200 MW of total power capacity across eight development phases. These are project plans reported in the source, not confirmation that every phase is built, funded or operational.
Marc Hayes, FläktGroup’s executive vice-president of data centres for the Americas, said the project reflects growing interest in liquid cooling as data-centre operators support AI applications. He described the work as evidence of the company’s ability to develop solutions for changing customer needs. Those comments are the company’s assessment; the report does not provide independent performance data or customer feedback about the unit.
A CDU for Expanding Data Hall Capacity
The announcement adds a 2.5 MW refrigerant-based CDU to the cooling equipment being developed for large data-centre projects. CDUs provide an interface for moving heat away from liquid-cooled IT equipment, while the refrigerant-based design described here differs from conventional liquid-to-liquid systems. The distinction may matter to operators evaluating cooling architectures, but the source does not offer comparative efficiency, cost or reliability figures.
The project’s planned scale helps explain the commercial relevance. A 25 MW first-phase data hall, a potential 50 MW second phase and a campus planned for 200 MW indicate that the equipment is being made for a large development, rather than a small demonstration. However, the stated figures describe intended capacity; they do not establish how much computing equipment is installed or how much power the site currently uses.
For FläktGroup, producing the unit is a reported manufacturing milestone and a move into a specific customer application. For other data-centre operators and suppliers, the development is a sign of continued work on cooling approaches for facilities designed to accommodate demanding workloads. Whether this particular system meets performance or operating targets will depend on deployment results that have not been reported.

Refrigerant-Based Cooling for AI Sites
The report frames the project against increasing adoption of liquid cooling for data centres supporting AI applications. Liquid-based systems are being considered as facilities plan for high-density computing, but the source does not quantify the growth in adoption or provide a comparison with air cooling.
FläktGroup says this CDU uses refrigerant-based cooling rather than a conventional liquid-to-liquid arrangement. The unit was designed with the customer for a specific project, so the announcement does not establish that the same configuration will be used at other sites. The reported development is the production of the first unit of this type for the company, not a claim that refrigerant-based CDUs are new to the wider industry.
“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.”
— Marc Hayes, FläktGroup’s executive vice-president of data centres for the Americas
Delivery and Performance Details Await
The source does not name the customer or provide a location for the U.S. project beyond describing the customer as being in the United States. It also gives no delivery, installation or commissioning dates, and does not say whether the first phase is under construction or when the planned expansions may proceed.
Technical information is limited. The report does not specify the refrigerant used, operating conditions, system efficiency, heat-rejection method, redundancy design or measured performance. It is also unclear whether the 2.5 MW rating refers to cooling capacity under particular test conditions or another stated measure, because no rating methodology is included. No independent confirmation or customer comment is provided.
The campus’s planned 200 MW capacity and the 25 MW and 50 MW data-hall figures should be read as project plans, not completed capacity. The source does not describe financing, permitting, construction progress or commitments for all eight phases.
Project Phases and Site Deployment
The next reported milestones would be delivery and deployment of the CDU, followed by operation within the project’s first phase. FläktGroup and the customer have not provided a schedule in the source, so the timing of those steps is not known.
Further updates could establish whether the 25 MW data hall enters service as planned, whether the second phase expands it to 50 MW, and how the wider campus advances through its eight planned phases. Operating data, if released, would help clarify the unit’s performance and how the refrigerant-based design compares with other cooling approaches. Until then, the confirmed development is production of the first 2.5 MW DX CDU for the customer, while the project’s expansion remains planned.
Key Questions
What has FläktGroup produced?
FläktGroup says it has produced its first 2.5 MW direct-expansion CDU, a refrigerant-based cooling distribution unit intended for a U.S. data-centre project.
Where was the CDU made?
The unit was built at FläktGroup’s Arkansas facility. The report does not identify the customer or give the project’s specific location.
How large is the planned data-centre project?
The first phase is designed to serve a 25 MW data hall. A second phase is planned to double that to 50 MW, within a wider campus planned for 200 MW across eight phases.
How does this CDU differ from a conventional design?
According to the report, this unit uses refrigerant-based cooling, unlike conventional liquid-to-liquid CDUs. The source does not provide comparative performance or efficiency data.
When will the unit be installed or begin operating?
No delivery, installation or commissioning date is given. The timing of the data hall’s planned phases is also not specified.
