European colocation firm Kolo DC has launched a new data center in Copenhagen, Denmark.

“We officially opened the doors to Kolo’s new Copenhagen data center, a state-of-the-art facility designed with AI-driven businesses and general IT workloads in mind,” the company said in a recent LinkedIn post. “As the demand for high-performance, sustainable, and sovereign infrastructure grows, we’re proud to provide a home for companies pushing the boundaries of artificial intelligence in Europe.”

On its website, Kolo lists one facility in Copenhagen: DK5 at Bygmestervej 10. The facility can reportedly offer 30kW per rack and features hot/cold aisle containment and a closed-loop cooling system. The company said the facility’s energy use is offset with renewable energy purchases.

Turnkey data center supplier DataCenterGruppen was involved in the project, described as a retrofit of an existing building that involved the deployment of liquid-cooled hardware.

“The project has been carried out with great focus on energy consumption and minimum environmental impact by replacing HFC refrigeration systems with efficient systems with natural refrigerants. In addition, a very efficient modular free cooler,” the company said. “The UPS system has been delivered with very high efficiency. Other components have been recycled to the greatest extent possible to keep the environmental impact of the entire process down.”

Kolo DC was formed earlier this year by Finnish investment firm CapMan.

CapMan Infra acquired three data centers earlier this year from Swedish data center operator EcoDataCenter, with plans to merge the acquired facilities with its previous data center investments, Serverius and Fuzion, under the Kolo name.

Today, Kolo has a dozen facilities in operation: five in Denmark, three in Sweden, and four in the Netherlands.

Founded in 1989, Nasdaq-Helsinki-listed CapMan Infra invests in energy, transportation, and telecommunications infrastructure across the Nordics with a focus on sustainability. It has €6.1 billion ($6.93bn) in assets under management. The CapMan Nordic Infrastructure II fund, established in 2022, made its final closing at more than €375 million ($500.4m) in April 2024.

In May 2023, CapMan acquired Dutch IT services provider Serverius and announced plans to build a new European data center platform. Founded in 2008, Serverius operates three colocation data centers in the Netherlands with a combined capacity of 8MW.

In September 2023, CapMan acquired Danish data center colocation firm Fuzion. Established in 2001, Fuzion offers colocation services, operating out of four data centers in the Jutland region of Denmark in Skanderborg, Viby J., Aarhus, and Randers. The company was also expanding to a new location in Copenhagen, likely the one now opened.

The EcoDataCenter sale comprised two facilities in Stockholm and one in Piteå.

Operators present in and around Copenhagen include Digital Realty, Stack, Penta Infra, AtNorth, AtlasEdge, GlobalConnect, Telia, Microsoft, and several local players and managed services providers.
