Liquid Cooling Technologies Driving Data Centre Efficiency

Castrol launches new fluid management service

Castrol, a British multinational lubricants company owned by BP, known for its presence in the automotive industry, has launched a new fluid management service for data centre liquid cooling, addressing a critical gap as the industry transitions away from traditional air-cooling systems. Announced at the Datacloud Global Congress 2025 in Cannes, France, Castrol’s new service model aims to cover all four phases of the data centre operation lifecycle: system start-up, ongoing maintenance, break-fix support, and fluid disposal. The approach is designed to help remove operational barriers in the adoption of liquid cooling in data centres. "Data centre operators recognise the benefits of liquid cooling but need assurance around long-term fluid management," states Peter Huang, Global Vice President of Data Centre Thermal Management at Castrol. "Castrol has delivered fluid services for the automotive industry for decades – we're now bringing this proven expertise to data centres with a service model that supports optimal performance throughout the entire lifecycle.” The four-phase service includes:1. System start-up support with fluid installation, filtration, system flushing, and certificates of analysis.2. Ongoing maintenance, such as laboratory testing, dynamic monitoring, predictive maintenance, and smart dosing capabilities.3. ‘Break-fix’ service, including telephone assistance, virtual engineering support, on-site response, and spare fluid availability.4. Support with fluid collection and disposal. Castrol’s service launch comes at a time when the data centre industry faces mounting pressure to improve cooling efficiency. Recent industry research indicates that traditional air-cooling systems struggle to handle increased computing demands from AI and edge computing applications, with 74% of data centre experts believing immersion cooling is now essential to meet current power requirements. "Our aim with this new service model is to remove the operational and technical uncertainties that have slowed liquid cooling adoption," says Andrea Zunino, Global Offer Development Manager at Castrol. "Within liquid cooling systems, the fluid represents a single point of failure – degraded conditions can reduce cooling capacity and lead to equipment failure. We're going beyond just fluid supply to deliver structured support at every stage, giving data centre operators the confidence they need to embrace liquid cooling.” The new service model will be deployed globally through Castrol's partner network. All services will be delivered with third-party suppliers. The availability and rollout of certain services may vary by location and may be introduced at different times depending on regional factors. For more from Castrol, click here.

Driven by dramatic increases in the adoption of AI, cloud computing, and other data-intensive technologies, the global data centre liquid cooling market is predicted to grow from $5.17 billion in 2025 to approximately $15.75 billion by 2030. Simultaneously, the demanding nature of AI workloads is pushing data centre thermal management requirements even further. With hardware such as Nvidia’s B300 and GB300 soon to arrive — and subsequent generations of even more powerful iterations inevitably following thereafter — the need to future-proof cooling capacity has never been greater. These increasingly sophisticated technologies generate far greater heat densities than traditional processing units, with rack power densities already exceeding 120kW per rack, and growing to 600kW by the end of 2027. "AI will keep pushing thermal output to new extremes, and data centres need cooling systems that can be easily deployed, managed, and scaled to match heat rejection demands as they rise,” says Joe Capes, CEO of LiquidStack. “With up to 10MW of cooling capacity at N, N+1, or N+2, the GigaModular is a platform like no other — we designed it to be the only CDU our customers will ever need. It future-proofs design selections for direct-to-chip liquid cooling without traditional limits or boundaries." Key features of the LiquidStack GigaModular CDU platform include: ● Scalable cooling capacity: A modular platform supporting single-phase, direct-to-chip liquid cooling heat loads from 2.5MW to 10MW. ● Pump module: An IE5 pump and dual BPHx, alongside dual 25um strainers. ● Control module: A centralised design with separate pump and control modules. ● Instrumentation kits: Centralised pressure, temperature, and EM flow sensors. ● Simplified service access: Serviceable from the front of the unit, with no rear or end access required, allowing the system to be placed against the wall. ● Optional configuration: Skid-mounted system with rail and overhead piping pre-installed or shipped as separate cabinets for on-site assembly. LiquidStack will showcase the new GigaModular CDU at Datacloud Global Congress in Cannes, France, from 3-5 June at the Palais des Festivals.

Supermicro introduces new direct liquid-cooling innovation

Supermicro has announced several improvements to its Direct Liquid Cooling (DLC) solution that incorporate new technologies for cooling various server components, accommodate warmer liquid inflow temperatures, and introduce innovative mechanical designs that enhance AI per watt. The Supermicro DLC-2 solution reduces data centre power consumption by up to 40% compared to air-cooled installations. These advanced technologies enable faster deployment and reduced time-to-online for cutting-edge liquid-cooled AI infrastructure. Additionally, the total cost of ownership decreases by up to 20%. The comprehensive cold plate coverage of components allows for lower fan speeds and fewer required fans, significantly reducing data centre noise levels to approximately 50dB. "With the expected demand for liquid-cooled data centres rising to 30% of all installations, we realised that current technologies were insufficient to cool these new AI-optimised systems," says Charles Liang, President and CEO of Supermicro. "Supermicro continues to remain committed to innovation, green computing, and improving the future of AI, by significantly reducing data centre power and water consumption, noise, and space. Our latest liquid-cooling innovation, DLC-2, saves data centre electricity costs by up to 40%." Supermicro aims to save 20% of data centre costs and apply DLC-2 innovations as part of data centre building block solutions to make liquid-cooling more broadly available and accessible. A significant component of the new liquid-cooling architecture is a GPU-optimised Supermicro server, which includes eight NVIDIA Blackwell GPUs and two Intel Xeon 6 CPUs, all in just 4U of rack height. This system is designed to support increased supply coolant temperatures. This unique and optimised design incorporates cold plates for CPUs, GPUs, memory, PCIe switches, and voltage regulators. This design reduces the need for high-speed fans and rear-door heat exchangers, thereby lowering cooling costs for the data centre. The new Supermicro DLC-2 stack supports the new 4U front I/O NVIDIA HGX B200 8-GPU system, and the in-rack Coolant Distribution Unit (CDU) has an increased capacity of removing 250kW of heat generated per rack. The Supermicro DLC-2 solution also utilises vertical coolant distribution manifolds (CDMs) to remove hot liquid and return cooler liquid to the servers for the entire rack. The reduced rack space requirements enables more servers to be installed, increasing computing density per unit of floor space. The vertical CDM is available in various sizes, precisely matching the number of servers installed in the rack. The entire DLC-2 stack is fully integrated with Supermicro SuperCloud Composer software for data centre-level management and infrastructure orchestration. The efficient liquid circulation and nearly full liquid-cooling heat capture coverage, at up to 98% per server rack, allow for an increase in the inlet liquid temperature at up to 45°C. The higher inlet temperature eliminates the need for chilled water, chiller compressor equipment cost, and additional power usage, saving up to 40% of data centre water consumption. Combined with liquid-cooled server racks and clusters, DLC-2 also offers hybrid cooling towers as well as water towers as part of data centre building blocks. The hybrid cooling towers combine the features of standard dry and water towers into a single design. This is especially beneficial in data centre locations with strong seasonal temperature variation to reduce usage of resources and costs further. Supermicro serves as a comprehensive one-stop solution provider with global manufacturing scale, delivering data centre-level solution design, liquid-cooling technologies, networking, cabling, a full data centre management software suite, L11 and L12 solution validation, onsite deployment, and professional service and support. With production facilities across San Jose, Europe, and Asia, Supermicro offers unmatched manufacturing capacity for liquid-cooled rack systems. This ensures timely delivery, reduced total cost of ownership (TCO), and consistent quality. For more from Supermicro, click here.
