European data center firm Data4 is deploying its first liquid cooled data halls outside Paris, France.

The company is deploying a direct liquid cooling (DLC) proof of concept (POC) project to its DC01 facility at its Marcoussis campus.

The commissioning is part of a “major retrofit” alongside Schneider and Danfoss. Data4 and Danfoss jointly designed a new optimized prototype cooling distribution unit (CDU) for the project.

Rentaload has also contributed the first hybrid load banks Liquid+Air, capable of diffusing heat both through air and through the DLC water network.

Data4 said this new equipment offers infrastructure testing capability, simulating racks of up to 140kW Liquid + 60kW Air Smart Load Bank.

Following this first deployment, Data4 said it had 250MW of DLC design projects currently in progress across all of its data centers.

Established in 2006 by Colony Capital (now DigitalBridge) and owned by Brookfield since April 2023, Data4 currently operates more than 30 data centers in France, Italy, Spain, Poland, and Luxembourg.

According to the company’s website, Data4 operates three campuses in Paris, which host dozens of data centers offering a combined capacity of 375MW.
