NorthC, Legrand upgrade Münchenstein (Basel) data centre

NorthC Data Centers, a Dutch provider of sustainable data centre and colocation services, has partnered with Legrand, a French multinational manufacturer of electrical and digital building infrastructure products, to upgrade its Münchenstein (Basel) site, introducing higher-density infrastructure to support AI, hybrid-cloud, and high-performance computing workloads. The project was completed within a six-month window to meet rising regional demand for GPU-driven environments. NorthC operates regional facilities across Switzerland, the Netherlands, and Germany. The company sought to replace low-density systems and traditional air-cooling at the Münchenstein site to accommodate higher power and thermal loads associated with modern AI deployments. Legrand, through USystems, supplied rear-door heat exchangers for rack-level cooling. These units are mounted to the rear of server racks, absorbing heat from server exhaust and transferring it through a heat exchanger before returning cooled air to the data hall. The closed-loop design supports higher rack densities while improving energy performance. The cooling equipment was installed while the data centre remained live, a process described by Wolfgang Voigt, Münchenstein Data Center Site Manager at NorthC, as “like open-heart surgery.” Focus on efficiency and future expansion NorthC reports that energy consumption at the site has fallen by about 80% following the cooling upgrade and broader infrastructure improvements. The facility now supports GPU-based clusters, hybrid-cloud environments, and high-density workloads, while maintaining compliance with Swiss data protection requirements. Wolfgang says, “Adopting the energy-efficient RDHx technology has been a game-changer for us. The fact that it enables high-density computing while reducing energy consumption makes it a compelling choice to meet AI and HPC requirements.” The upgraded design also accommodates future development, including additional rack capacity or a shift towards liquid or direct-to-chip cooling. NorthC says it continues to pursue its long-term sustainability goals through efficiency measures and ongoing optimisation of existing sites. Colin Rowlands, European Technical Support at USystems, notes, “Installing the basic infrastructure for our cooling solutions in a data centre, whether in the entire data centre or just part of it, makes upgrading easy. "The joint solution, which we are very proud of, provides NorthC with future-proof and flexible infrastructure.” For more from NorthC, click here.

Secure I.T. constructs modular DC for NHS Trust

Secure I.T. Environments (SITE), a UK design and build company for modular, containerised, and micro data centres, has today announced the handover of its latest external modular data centre project with Somerset NHS Foundation Trust. The new 125m² data centre has now been completed and provides an energy-efficient disaster recovery facility for the Trust, ensuring it can continue to deliver resilient services across Somerset and for the 1.7 million patient contacts that take place. A data centre for all challenges Whilst the Trust initially considered cloud solutions for its data requirements, these could not meet the requirements for existing clinical software, nor the cost constraints in place. In response, SITE proposed its external modular data centre, which is intended to provide a cost-effective and secure way to build new data centres or extend existing infrastructure to meet the growing demands of on-site IT needs. SITE says its modular system can be built rapidly and that this particular project was designed, built, and live within 8 months. The company also says its modular rooms are a pre-engineered solution, offering a clean and fast construction process, making it appropriate for locations where an existing room is not available or where a new building is impractical. The modular system reportedly has high protection, including protecting against physical security threats by meeting industry standards BS476 / EN1047 and LPS1175 security ratings. Design and delivery The design was divided into three areas: the main IT racks, an electrical plant area, and build area. Working with the Trust, SITE’s design incorporated 20 19” 48U cabinets, configured in two rows of 10 with cold aisle containment, energy-efficient UPS systems in N+1 format, as well as GEA Multi-DENCO Energy Efficient DX Freecool air conditioning units, also in N+1 configuration. SITE managed the delivery of all groundworks and mechanical and electrical infrastructure. The delivery of the new facility included a new concrete pad, drainage, power distribution, FK 5-1-12 fire suppression, VESDA detection systems, environmental monitoring, backup generator, and fuel tank. Furthermore, the design and specification hardened the data centre against burglary (LPS 1175 SR2 specifications), fire, fire-fighting water, heat, humidity, gases, dust, debris, and unauthorised access. The facility's external perimeter security has been protected with CCTV, prison mesh anti-climb fencing, security gates, and Amcor barriers. Chris Wellfair, Projects Director at Secure I.T. Environments, comments, “At a time when many organisations are trying to balance the needs of their IT infrastructure with challenging budgets, our modular data centres are making it easier for them to achieve their goals without compromising on performance. "Having previously built a data centre for the Trust at another hospital location, we were pleased to work with Somerset NHS Foundation Trust to deliver this new data centre to meet their specific requirements.” Adam Morgan, Deputy Chief Technology Officer at Somerset NHS Foundation Trust, adds, “Secure I.T. have delivered a significant upgrade to the Trust’s data centre infrastructure. "We were very specific about the design brief and requirements, and it has been a positive project delivering this facility with Secure I.T. Environments. "The Trust now has additional capacity for growth for years to come, which will bring benefits to clinical care by enabling resilient delivery of clinical systems across the county of Somerset.” For more from Secure I.T.

"Our goal is to ensure that British enterprise, researchers, and public institutions have access to world-class compute capacity without relying on foreign-controlled infrastructure. "The Government recognises the urgency; that is why they have said we need 6GW of sovereign AI capacity by 2030. Together, we can get there, securing a foundation for innovation, investment, and long-term national advantage.” Carbon3.ai asserts that these developments support the UK Government’s AI and digital infrastructure agenda of strengthening national resilience, creating regional opportunity, and ensuring the benefits of technological progress are rooted in British infrastructure and communities. By converting brownfield and legacy energy sites into renewable-powered compute hubs, the company says it aligns directly with the Government’s priorities for AI growth zones and the designation of data centres as critical national infrastructure.

R&M introduces radio-based access control for racks

R&M, a Swiss developer and provider of infrastructure for data and communications networks, is introducing radio-based access control for data centres. The core product is an electromechanical door handle for the racks of the BladeShelter and Freenet families from R&M. Technicians can only open the door handles with authorised transponder cards, while administrators can control them remotely via encrypted radio connections and data networks. R&M says it is thus integrating high-security digital protection into its "holistic infrastructure solutions" for data centres. Package details One installation comprises up to 1,200 door handles for server and network racks, as well as radio and control modules for computer rooms. The door handles do not require any wiring in the racks. Their electronics are powered by batteries whose power is sufficient for three years of operation or 30,000 locking cycles. The personalised transponder cards communicate with the door handles via RFID antennas. In addition, there is software to manage users, access rights, the transponder cards, and racks. The software creates protocols, visualises alarm states, and supports other functions. It can be operated remotely and integrated into superordinate systems such as data centre infrastructure management (DCIM). The new offer is the result of the collaboration with German manufacturer EMKA, being based on the company's 'Agent E', an intelligent locking system. The R&M offering aims to integrate complementary systems from selected manufacturers into infrastructure for data centres. In Europe, R&M notes it is already working with several independent partner companies that pursue comparable medium-sized business models and sustainability goals. For more from R&M, click here.

Why cooling design is critical to the cloud

In this article for DCNN, Ross Waite, Export Sales Manager at Balmoral Tanks, examines how design decisions today will shape sustainable and resilient cooling infrastructure for decades to come: Running hot and running dry? Driven by the surge in AI and cloud computing, new data centres are appearing at pace across Europe, North America, and beyond. Much of the debate has focused on how we power sites, yet there is another side to the story, one that determines whether those billions invested in servers actually deliver: cooling. Servers run hot, 24/7, and without reliable water systems to manage that heat, even the best-connected facilities cannot operate as intended. In fact, cooling is fast becoming the next frontier in data centre design and the decisions made today will echo for decades. A growing thirst Data centres are rapidly emerging as one of the most significant commercial water consumers worldwide. Current global estimates suggest that facilities already use over 560 billion litres of water annually, with that figure set to more than double to 1,200 billion litres by 2030 as AI workloads intensify. The numbers at an individual site are equally stark. A single 100 MW hyperscale centre can use up to 2.5 billion litres per year - enough to supply a city of 80,000 people. Google has reported daily use of more than 2.1 million litres at some sites, while Microsoft’s 2023 global consumption rose 34% year-on-year to reach 6.4 million cubic metres. Meta reported 95% of its 2023 water use - some 3.1 billion litres - came from data centres. The majority of this is consumed in evaporative cooling systems, where 80% of drawn water is lost to evaporation and just 20% returns for treatment. While some operators are trialling reclaimed or non-potable sources, these currently make up less than 5% of total supply. The headline numbers can sound bleak, but water use is not inherently unsustainable. Increasingly, facilities are moving towards closed-loop cooling systems that recycle water for six to eight months at a time, reducing continuous draw from mains supply. These systems require bulk storage capacity, both for the initial fill and for holding treated water ready for reuse. Designing resilience into water systems This is where design choices made early in a project pay dividends. Consultants working on new builds are specifying not only the volume of water storage or the type of system that should be used but also the standards to which they are built. Tanks that support fire suppression, potable water, and process cooling need to meet stringent criteria, often set by insurers as well as regulators. Selecting materials and coatings that deliver 30-50 years of service life can prevent expensive retrofits and reassure both clients and communities that these systems are designed to last. Smart water management, in other words, begins not onsite, but on the drawing board. For consultants who are designing the build specifications for data centres, water is more than a technical input; it is a reputational risk. Once a specification is signed off and issued to tender, it is rarely altered. Getting it right first time is essential. That means selecting partners who can provide not just tanks, but expertise: helping ensure that water systems meet performance, safety, and sustainability criteria across decades of operation. The payback is twofold. First, consultants safeguard their client’s investment by embedding resilience from the start. Second, they position themselves as trusted advisors in one of the most scrutinised aspects of data centre development. In a sector where projects often run to tens or hundreds of millions of pounds, this credibility matters. Power may dominate the headlines, but cooling - and by extension water - is the silent foundation of the digital economy. Without it, AI models do not train, cloud services do not scale, and data stops flowing. The future of data centres will be judged not only on how much power they consume, but on how intelligently they use water - and that judgement begins with design. If data centres are the beating heart of the modern economy, then water is the life force that keeps them alive. Cooling the cloud is not an afterthought; it is the future.

ABB supplies power tech for Applied Digital's AI factory

BAC releases upgraded immersion cooling tanks

Baltimore Aircoil Company (BAC), a provider of data centre cooling equipment, has introduced an updated immersion cooling tank for high-performance data centres, incorporating its CorTex technology to improve reliability, efficiency, and support for high-density computing environments. The company says the latest tank has been engineered to provide consistent performance with minimal maintenance, noting its sealed design has no penetrations below the fluid level, helping maintain fluid integrity and reduce leakage risks. Dual pumps are included for redundancy and the filter-free configuration removes the need for routine filter replacement. Design improvements for reliability and ease of operation The tanks are available in four sizes - 16RU, 32RU, 38RU, and 48RU - allowing operators to accommodate a range of immersion-ready servers. Air-cooled servers can also be adapted for immersion use. Each unit supports server widths of 19 and 21 inches (~48 cm and ~53 cm) and depths up to 1,200 mm, enabling higher rack densities within a smaller footprint than traditional air-cooled systems. BAC states that the design can support power usage effectiveness levels of up to 1.05, depending on the wider installation. The system uses dielectric fluid to transfer heat from servers to the internal heat exchanger, while external circuits can run on water or water-glycol mixtures. Cable entry points, the lid, and heat-exchanger connections are fluid-tight to help prevent contamination. The immersion tank forms the indoor component of BAC’s Cobalt system, which combines indoor and outdoor cooling technologies for high-density computing. The system can be paired with BAC’s evaporative, hybrid, adiabatic, or dry outdoor equipment to create a complete cooling configuration for data centres managing higher-powered servers and AI-driven workloads.
