Datacenter United signs multi-megawatt capacity agreement

Datacenter United, an independent Belgian data centre operator, has signed a binding agreement to provide multi-megawatt data centre capacity for AI workloads at DC Machelen in Belgium. The environment will use liquid cooling to support the power densities and heat loads associated with high-density AI systems. The customer's identity and commercial terms of the agreement will remain confidential. AI systems concentrate increasing amounts of computing power within a limited footprint, raising both the power required per rack and the amount of heat that must be removed. Power supply, cooling, connectivity, redundancy, and operations must, therefore, be engineered as an integrated environment. Liquid cooling removes heat closer to its source and can enable high-density configurations that are increasingly difficult to support with air cooling alone. The system at DC Machelen will be engineered around the customer's confirmed architecture and operational requirements. The agreement reflects demand for specialised AI infrastructure in Belgium, with the project moving from planning to deployment. Liquid cooling for high-density AI Friso Haringsma, CEO of Datacenter United, comments, “Demand for specialised AI infrastructure in Belgium is moving from ambition to actual deployment. "This binding agreement translates a specific customer requirement into a concrete, multi-megawatt project in Machelen. It demonstrates that a Belgian operator can support high-density AI workloads at this scale.” The liquid-cooling design is intended to support higher computing densities whilst improving cooling and energy efficiency. Datacenter United says the project also demonstrates the importance of access to power, connectivity, suitable locations, and predictable permitting for AI infrastructure development in Belgium. DC Machelen is designed for organisations with high power and capacity requirements. The site combines power, space, carrier-neutral connectivity, and the flexibility required for large-scale, high-density infrastructure. Technical implementation will proceed according to the agreed system configuration and deployment plan. Further information on the commissioning schedule is set to be provided at a later stage.

Schneider Electric expands prefabricated power portfolio

Global energy technology company Schneider Electric has launched a range of standardised Prefabricated Power Modules and Power Skids for hyperscale, neocloud, and colocation data centres supporting AI and high-performance computing workloads. Powered by the company’s Galaxy VXL UPS technology, the prefabricated power modules provide up to 2.5MW of capacity per module. Standard configurations are available at 2MW, 2.25MW, and 2.5MW, allowing multiple units to be deployed as repeatable power blocks across larger data centre campuses. The systems are based on Schneider Electric’s reference designs with NVIDIA, including integrated power management and liquid cooling controls for the GB300 NVL72 platform. They are intended to support AI training clusters and other GPU-intensive workloads. Standardised systems target faster deployment Schneider Electric says traditional customised prefabricated power systems can require lead times of 12–14 months. Its standardised approach is intended to simplify specification, design, and manufacturing, with production possible in as little as six months. The modules combine UPS, switchgear, cooling systems, lithium-ion batteries, busway, and power distribution within a factory-tested enclosure. The power skids provide similar electrical infrastructure in an open format for indoor deployment. Tarunjeet Sarao, SVP Data Center Systems at Schneider Electric, says, “Today’s data centre operators are under immense pressure to deploy AI-ready infrastructure faster, more efficiently, and at greater scale. “By standardising our prefabricated power systems and incorporating our leading Galaxy VXL UPS technology, we are enabling hyperscale, neocloud, and colocation providers to deploy scalable, high-density power infrastructure in months rather than years.” The modules and skids are engineered, manufactured, and tested at Schneider Electric’s facility in Sant Boi de Llobregat, Barcelona. The products are available immediately in Europe, with North American availability planned later this year, followed by other international markets and APAC.

ESA funds €1.5m automated satellite backup for subsea cables

The European Space Agency (ESA) has selected multi-orbit satellite communications specialist neXat to lead a €1.5 million (£1.2 million) project developing automated satellite backup for submarine fibre networks. neXat will work with satellite operator Telesat and telecoms infrastructure provider Colt Technology Services Belgium to develop and demonstrate CableShield, a system designed to detect submarine cable interruptions and automatically reroute affected traffic through satellite connectivity. Submarine cables carry an estimated 99% of intercontinental data traffic, whilst around 30% of tracked cables experience at least one fault each year. Repairs can take 10 to 20 days, potentially leaving critical services without their normal connectivity. CableShield automates traffic failover CableShield will use multiple satellite providers through a ‘Pooling and Sharing’ model. When a cable interruption is detected, the platform will select the required satellite capacity and reroute a controllable proportion of traffic, with routing and prioritisation protocols used to establish an end-to-end connection. The system will combine detection and decision-making with terrestrial and satellite control layers through a common orchestration framework. These layers will communicate using APIs defined through ESA’s Pooling and Sharing Interface Definitions, enabling multi-vendor, multi-orbit systems to exchange data and manage shared capacity. Caroline De Vos, COO of neXat, explains, “Submarine cables carry an estimated 99% of global connectivity, so when they go down, entire regions can lose access instantly, disrupting business, public services, and other critical communications. “Satellite provides the lifeline that keeps essential services online when their primary connectivity is gone.” The project will run for 18 months of development and validation, with commercial launch targeted for 2028 alongside the planned entry into service of Telesat’s Lightspeed constellation.

AVK launches capital business for on-site data centre power

AVK, a provider of power systems and electrical infrastructure for data centres, has launched AVK Capital, a funding entity that will finance and own on-site power infrastructure for data centres, with customers accessing the capacity through long-term power purchase agreements (PPAs). The business houses investment secured by AVK from Partners Group in August 2026. The model is intended to give data centre developers access to on-site power without carrying the infrastructure costs on their own balance sheets. Under the model, AVK selects and engineers the power infrastructure for each site, whilst AVK Capital funds and owns the assets. The customer then pays for the power as an operating cost rather than making the upfront capital investment. The infrastructure can incorporate microgrids, AVK PowerPods, fuel cells, renewable energy, and standby generation. AVK will remain responsible for the delivery, commissioning, operation, and maintenance throughout the asset’s operating life. Funding aims to accelerate power delivery AVK says the model addresses two barriers facing data centre development: constrained grid capacity and the capital cost of providing on-site generation. Ben Pritchard, Chief Executive Officer at AVK, explains, “Access to power is the single biggest constraint on data centre development in Europe, and the cost of solving it is the second. AVK Capital takes both off the table. “We already design, build, operate, and maintain on-site power at commercial scale, and being able to fund and own it as well means a developer can contract for power in the same way they contract for any other service.” AVK Capital will sit alongside AVK’s existing business, which will continue to deliver standby, prime, and modular power infrastructure for customers that choose to fund projects themselves. Bob Downing, VP of Sales, Energy Solutions at AVK, suggests that bringing financing and engineering together can reduce the number of handovers during a project. He notes, “We can sit down with a developer, agree what the site needs, agree how it is paid for, and then go and build it, without a chain of handovers in between.” AVK Capital is set to be introduced to the market this month.

Aggreko achieves grid code compliance across Europe

Aggreko, a British multinational temporary power generation company, has achieved grid code compliance for its 1.5MW generator fleet across 11 European countries, allowing the company to support data centres and other large power projects facing grid capacity constraints. The certification covers the UK, Ireland, Germany, France, Italy, Spain, the Netherlands, Belgium, Poland, Romania, and Czechia. It allows Aggreko’s generators to integrate with public electricity networks for applications including additional generation capacity, peak demand management, exporting power to the grid, and grid balancing. Aggreko says the certification can also help accelerate large-scale power projects, with gas-powered generation of more than 50MW potentially deployed within months while longer-term grid infrastructure is developed. Generation supports grid capacity The company says decentralised generation can help address capacity shortfalls, support renewable energy integration, and reduce pressure on electricity networks. Aggreko has previously supplied 43MW of power to Romania’s national grid over four years, using a combined heat and power system while providing grid balancing services. Connor Docherty, Head of Product for Gas at Aggreko, suggests, “Decentralised energy will have a critical role to play during this critical period, which is where grid code compliance comes into play. “With the ability to integrate with grid infrastructure, we can support grid operators and high energy users alike through decentralised energy generation. This will help to balance the grid, make up capacity shortfalls to ensure that large power projects can go ahead, assist increased renewable integration, and avoid blackouts.” Aggreko says that its fleet also incorporates remote monitoring and control systems for equipment diagnostics and plant-level analytics.

Circular thinking: A new imperative for data centre cooling

In this article for DCNN, Todd Scheving, Business Development Director – Global Data Center at A-Gas, outlines why a circular approach to refrigerant management is becoming increasingly important as data centre operators balance cooling requirements with sustainability and supply considerations: The AI revolution has sparked heated debate about data centre cooling. Refrigerant decisions are emerging earlier in the value chain, spurring pressing procurement and sustainability conversations. This is for good reason: the choices operators make today will shape emission footprints for the next decade. Maintaining a circular approach to data centre cooling is more important than ever. The industry is feeling the effects. Firms are engaging with refrigerant suppliers far earlier in the planning process, integrating their sustainability teams. Questions about supply security and reclaim options are now a fixture in project conversations. In short, sustainability targets are turning refrigerants into strategic assets that must be managed. This reclassification from commodity to asset matters. Managing refrigerants holistically reveals hidden problems. Often, the solutions involve maintaining a circular approach to cooling: recover, reclaim, and destroy only what cannot be restored to spec. Reclaimed refrigerants have a significantly lower carbon footprint than virgin alternatives because the molecules already exist. Rather than venting (which is illegal across North America and the European Union) or leaving them in storage, the goal is to keep refrigerants in circulation. Circular thinking is the environmentally responsible path and, increasingly, the economically rational one. End-of-life handling is responsible for much of the industry's emission problem. Unfortunately, despite it being illegal, venting is often a by-product of strict time constraints during decommissioning or servicing. The solution is to engage dedicated, high-speed refrigerant recovery teams to recover refrigerants and deliver them to reclaimers for reprocessing for future reuse. Recovery is the future of cooling. There are enough HFCs (hydrofluorocarbons) already installed today to meet industry needs for the foreseeable future, provided they are managed responsibly. The infrastructure exists; operators must now partner with recovery teams to treat refrigerants like the strategic assets they were always meant to be. For more from A-Gas, click here.

STULZ introduces fourth-generation cooling units

STULZ, a manufacturer of mission-critical air conditioning technology, has introduced the fourth generation of its TelAir and WallAir cooling series for edge, 5G, and critical infrastructure applications. The TelAir 4 and WallAir 4 units use R454C refrigerant, integrated free cooling, and an EN 378-compliant safety architecture. They are designed for edge data centres, telecommunications containers, shelters, and radio stations. The units are available with two installation concepts: TelAir 4 is designed for indoor installation, whilst WallAir 4 can be mounted externally on a container wall. Anika Do, Global Product Manager at STULZ, explains that, "Both are available in two standard enclosure sizes and four cooling capacity classes, ranging from 6–17kW." The units are designed to address increasing thermal densities and the requirements of the amended European F-Gas Regulation (EU) 2024/573. Free cooling cuts energy use STULZ says the units can reduce operating costs by up to 80% when using combined free cooling and mixed-mode operation. The electronically commutated (EC) fans also comply with the requirements of the upcoming ErP 2027 Ecodesign Directive. Both models operate from -20°C to +54°C, while an optional winter kit can extend operation down to -40°C. Customers can choose between on/off systems with a thermostatic expansion valve, or continuously modulating EC inverter compressors paired with an electronic expansion valve. Both configurations have hermetically sealed refrigeration circuits. The units also feature a multi-stage safety architecture designed for A2L refrigerants such as R454C. In the event of a refrigerant leak, the evaporator fan can increase to maximum speed to dilute and extract refrigerant gases. A two-stage sensor system activates maximum fan speed and shuts down other power consumers at 10% of the lower flammability limit (LFL). At 20% LFL, the unit is fully disconnected from the power supply. Meanwhile, an enclosed IP54 control cabinet is designed to eliminate potential ignition sources. TelAir 4 supports downflow and displacement airflow concepts, with optional adjustable outlet grilles for horizontal or vertical air distribution. WallAir 4 uses displacement cooling to provide direct cold air stratification within the room. Additionally, TelAir 4 specifically can be installed within a wall, providing protection against weather and vandalism, whilst also reducing noise emissions for use in residential and mixed-use areas. Both units use the E² BASIC controller, which includes an ethernet interface, Modbus, and multiple inputs and outputs for integration with building management and data centre infrastructure management (DCIM) systems. Password-protected access levels are included, alongside inputs for monitoring fire, smoke, and intrusion alarms. Anika continues, "For the fourth generation of the TelAir and WallAir cooling series, we set out to create two distinct cooling solutions that deliver outstanding flexibility across a wide range of edge, 5G, and critical infrastructure applications. "By combining cutting edge technology with modern design, ease of use, energy efficiency and reliability, we have achieved that goal. The new units are available to order immediately, with STULZ account managers able to provide further information and tailored advice." For more from STULZ, click here.

aquatherm blue powers cooling at Novva’s data centre

At the hyperscale Novva data centre near Salt Lake City, USA, the operator’s cooling strategy is designed for maximum reliability and future orientation. The core of the waterless cooling concept is the PP‑RCT piping system aquatherm blue, which circulates the cooling medium in a closed loop and makes traditional evaporation cooling – and its high water consumption – unnecessary. Corrosion- and incrustation-free pipes ensure stable flow rates over the long term and significantly reduce leakage risks – a key factor for protecting critical IT infrastructure. Thanks to their low weight and welded joints, aquatherm blue could be integrated into the extensive underfloor construction. To learn more about the project at Novva data centre, click here.
