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.

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.

Signings for European AI DC capacity treble in 2025

Demand for data centre capacity dedicated to artificial intelligence (AI) has surged across Europe this year, as emerging AI infrastructure providers - often referred to as neoclouds - accelerate their expansion efforts amid slowing hyperscaler activity. According to new research from commercial real estate and investment firm CBRE, signings for AI-focused colocation capacity reached 414MW in the first nine months of 2025, up from 133MW compared to the same period in 2024. More than half of this capacity (57%) was signed in the Nordics. The increase reflects a market shift as hyperscaler demand has moderated temporarily and neocloud providers are securing large-scale capacity to meet the growing requirements of AI-driven applications. Neoclouds taking the lead Data centre operators are implementing measures to manage the additional risk associated with leasing to neocloud firms, including higher rental rates to offset build costs and ensure returns on AI-ready facilities. Andrew Jay, Head of Data Centre Solutions, Europe at CBRE, notes, “Neoclouds have expanded their footprint in Europe this year by absorbing vacant space that was originally intended for hyperscalers. "It is a sign that many data centre providers are growing more comfortable with the ambitions of neocloud providers and the covenants that come with it.” Kevin Restivo, Director, European Data Centre Research at CBRE, adds, “Neocloud providers are taking AI-specific capacity at scale in Europe. "We see tremendous growth of this segment especially in the Nordics, where lower-cost renewable power is often available in greater abundance than in many other European markets.” For more from CBRE, click here.

National Grid upgrading Oxfordshire substation to connect DCs

National Grid, the UK’s largest electricity distribution network, has started work to upgrade its Didcot substation in Oxfordshire, a key infrastructure development that will connect data centres and battery energy storage systems (BESS) to the electricity transmission network. Situated next to the former Didcot A coal power station and just two miles from the UK’s first AI Growth Zone at Culham, the upgraded substation is aimed at supporting Britain’s digital ambitions while boosting grid capacity for future projects to plug in. Alongside new data centres, 650MW of battery schemes will connect through the extended facility, completing a transition from ‘coal to clean’ at the site and helping to meet growing demand for flexible, zero carbon power in the region. Details of the upgrades The upgrade will see the existing 400kV outdoor air-insulated substation extended with three bays and three supergrid transformers, while a new 132kV indoor gas-insulated switchgear (GIS) facility will be built next door, minimising the footprint of the development and its impact on the environment. The new GIS facility will feature Hitachi Energy’s EconiQ switchgear technology, a sustainable alternative to sulphur hexafluoride (SF6) - a greenhouse gas commonly used as an electrical insulator - marking another step in National Grid’s commitment to reduce SF6 emissions from its network by 50% by 2030. Linxon has been appointed as principal contractor to deliver the substation upgrades, building on its collaboration with National Grid on projects such as London Power Tunnels, which will see the UK’s first SF6-free GIS substation at Bengeworth Road. Work at Didcot comes just months after construction commenced on National Grid’s new Uxbridge Moor substation in neighbouring Buckinghamshire, which is due to connect over a dozen new data centres and which will also use SF6-free switchgear. Peter Hancock, Project Director at National Grid Electricity Transmission, says, “Our Didcot substation extension marks another step forward in powering the UK’s digital future. "By enabling new data centres and battery storage systems to connect to the grid, we’re supporting both the energy transition and the growth of the digital economy regionally and nationally. “With SF6-free technology at its heart, this project reflects our commitment to building a cleaner, greener electricity network for generations to come.” Angel Guijarro, Managing Director of Linxon Europe, adds, “Linxon’s appointment to this project is a testament to our strong partnership with National Grid and our shared vision for a sustainable energy future. "We are committed to delivering a turnkey solution that will enhance the reliability and efficiency of Didcot substation, benefitting both local and national communities.” Electricity demand in Britain is expected to double by 2050, with demand from data centres alone set to triple from 3% of the country’s total in 2025 to 9% by 2035.

AI rush deemed "incompatible" with Clean Power Plan

A forecast suggests that the UK data centre boom is at odds with the UK’s clean power commitments, with the sector already overwhelming the electricity system and forcing an unavoidable reliance on gas. This is the view put forward by Simon Gallagher, Managing Director at UK Networks Services, speaking at Montel's UK Energy Day event earlier today (13 November). Simon said that only firm capacity be counted on in the context of powering data centres, as adverse weather conditions would reduce the availability of wind and solar during periods of low wind and sunlight. When asked what could realistically power tens of gigawatts worth of near constant data centre load, Simon said his “controversial opinion” was that this demand “is going to have to be met by gas.” “It’s the only technology we have that can do this on a firm basis. We don’t have storage,” Simon added. This led him to conclude that the sector’s growth was simply not compatible with the UK government’s Clean Power 2030 plans, under which 95% of energy must come from low-carbon sources by the turn of the decade. Physical limitations This comes amid an explosion in grid connection requests, jumping from around 17 GW to 97 GW over the summer, pushing the total capacity waiting for connections to the UK grid up to 125 GW. Simon continued, “About 80% of that is hyperscale data centres. It’s all AI. The impact on our grid is very real – and it just happened.” The UK was “never, ever” going to build the required transmission capacity in time, Simon added, with a new connection taking “at least five years.” He also outlined how the infrastructure available is not where data centres want to be, adding that such facilities seek sizeable connections “at transmission voltage, in urban areas near fibre.” This would typically site them away from significant power generation zones, which could help to alleviate network constraints and reduce balancing costs. Earlier today, Dhara Vyas, CEO of trade group Energy UK, told the same event that the UK’s clean energy expansion was being slowed by planning rules and grid connection queues that were “actively deterring investors”.

OPTEX introduces indoor LiDAR sensor for DC security

OPTEX, a manufacturer of intrusion detection sensors and security systems, has launched the REDSCAN Lite, a short-range indoor LiDAR sensor designed to provide precise and rapid detection for protecting critical infrastructure within data centres. Founded in Japan in 1979, OPTEX has developed a series of sensor innovations, including the use of LiDAR technology for security detection. The company says its REDSCAN range is recognised for improving the accuracy and reliability of intrusion detection in sensitive environments. Addressing physical security risks in critical environments As data centres across the UK and EU are now classified as critical infrastructure, operators face increasing pressure to meet strict security standards and mitigate both internal and external risks. Industry data indicates that nearly two thirds of data centres experienced a physical security breach in the past year. The REDSCAN Lite uses 2D LiDAR technology to detect intrusions within a 10 m x 10 m range, reportedly responding in as little as 100 milliseconds. The sensor can be positioned vertically to create invisible ‘laser walls’ around assets such as server racks, ventilation conduits, and access points, or horizontally to protect ceilings, skylights, and raised floors. Engineered for high-density environments, the REDSCAN Lite is capable of detecting small-scale activities such as the insertion of USB drives or LAN cables through server racks. It is designed to operate effectively despite temperature fluctuations, low light, or complete darkness, helping reduce false alarms common in traditional systems. Purpose-built for confined data centre spaces Mac Kokobo, Head of Global Security Business at OPTEX, says the product was developed in response to growing demand from data centre operators, noting, “In today’s modern environments, such as data centres, spaces are becoming tighter and tighter filling with racks and processors. "This latest REDSCAN Lite has been developed to meet the specific need for rapid detection in tight indoor spaces where high security is crucial. “Feedback from customers highlighted a clear need for enhanced protection in small, narrow areas and spaces, so the REDSCAN Lite sensor has been designed to fit into the narrow gaps and is engineered to provide highly accurate and fast detection in indoor spaces that other technologies simply cannot reach.” The REDSCAN Lite RS-1010L is now available for deployment.
