KAYTUS, a leading IT infrastructure provider, announced its new generation V3 server family, equipped with fully optimized liquid cooling technology. These servers operate with comprehensive liquid cooling solutions for components, nodes, servers and entire data centers. The V3 servers are designed to address challenges related to cooling and increasing energy consumption, enabling users to meet the demands of the rapidly evolving AI landscape efficiently and reliably.
The increase in computing power and density in AI systems has led to a significant increase in energy consumption. According to the International Energy Agency (IEA), electricity use in data centres is expected to double by 2026 compared to 2022, with approximately 40% of this energy being used for cooling 1 . In response, governments are implementing stricter compliance requirements. Starting this year, European data centre operators will have to report key energy consumption metrics to the European Union (EU) annually 2 to support the sustainable development of data centres. Liquid cooling is considered a next-generation cooling technology and is covered extensively in the Best Practice Guidelines for the EU Code of Conduct on Data Centre Energy Efficiency 3 document , which sets out a strategy to make data centres energy efficient and sustainable.
State-of-the-art liquid cooling technology optimized for AI applications
The KAYTUS V3 server product portfolio features advanced liquid cooling solutions that utilize innovative technologies such as two-phase cold plates, vacuum systems, and special coatings for motherboard circuit boards. These advances improve safety, efficiency, and performance.
The storage cooling solution’s innovative “sleeper” architecture combined with a waterless hard drive heat exchange system supports different thicknesses of memory modules and drives. KAYTUS’s liquid-cooled rack-scale servers feature superior cooling performance, flexible node flexibility, and robust leak protection, and include standardized liquid cooling components that enable smooth integration.
Designed with energy efficiency in mind, the V3 server series incorporates global component-level temperature monitoring, with precise and fine-tuned control of high-performance fans improving fan cooling performance by 20%. Equipped with Titan power supplies as standard, the series achieves conversion efficiency of over 98%. These power supply units (PSUs) maintain their exceptionally high conversion efficiency even when server loads vary between 20% and 50%.

Consistent expertise: Robust liquid cooling solutions from R&D to delivery
Liquid cooling is a complex technology involving issues of system architecture, components, interfaces, hardware platforms, and monitoring systems, making the creation of a fully liquid-cooled data center a tremendous challenge. KAYTUS demonstrates its robust capabilities in all phases—R&D, production, testing, and delivery—enabling users to manage the complexities associated with deploying a large-scale liquid-cooled server implementation. With a commitment to strict quality control and proven reliability in a wide range of industrial applications, KAYTUS ensures outstanding system performance and durability. The company has developed and integrated core components—including cabinet and mobile coolant distribution units (CDUs), quick-disconnect couplings, manifolds, and low-flow cold plates—into innovative products such as fully liquid-cooled servers and cabinets. With these full lifecycle solutions, the company develops complete liquid cooling solutions as seamlessly integrated, turnkey projects that receive widespread approval from its customers.
R&D: Building on advances in thermodynamic theory, materials research and structural optimization, KAYTUS has developed innovative solutions for coolant distribution units (CDUs), components and cold plates. With these innovations, the company addresses key challenges such as high-efficiency component cooling with cold plates and leakage protection, ensuring robust and reliable performance.
- To reduce the risk of fluid leakage, KAYTUS has developed a liquid ring vacuum coolant distribution unit that creates a negative pressure in the secondary line. This allows the coolant to circulate through a combination of vacuum and multi-chamber switching mechanisms. Any leaked coolant is automatically ‘sucked’ back into the pipeline, effectively eliminating the risk of leakage. Compared to conventional high-pressure pumps, the innovative use of vacuum pumps for multi-chamber switching ensures a uniform coolant flow, which significantly simplifies the entire system design.
- To improve component cooling, KAYTUS has developed innovative solutions such as the “sleeper” architecture memory cooling, the direct heat exchange drive cooling and aluminum brackets for the CPU cooling plates. These innovations enable liquid cooling for all components and bring about significant improvements in cooling efficiency, a significant reduction in noise and energy consumption, and they enable a PUE value of almost 1 to be achieved. The design of the “sleeper” architecture memory cooling is based on railway sleepers and has resulted in a “sleeper” module consisting of aluminum heat sinks, heat pipes, clips and DIMMs. This module rests on “rails” in the form of cold plate channels at both ends, which achieve twice the cooling efficiency of air cooling. Its decoupled structure also allows for a streamlining of operation and maintenance processes.
- For cold plate based cooling, KAYTUS has developed a low flow resistance solution characterized by enlarged and optimized flow channels, achieved through structural innovation. Compared to traditional cold plates with corrugated straight channels, this modern design reduces flow resistance, improves coolant throughput, increases cooling efficiency and maximizes CDU utilization.
Production: KAYTUS has compiled a comprehensive set of technical specifications for production to high standards. The spectrum of these specifications ranges from material selection for components to advanced processing technologies, creating the necessary conditions for large-scale production. For component selection, the use of FEP corrugated tubes improves the cooling plates’ corrosion resistance and impact resistance, allowing the liquid cooling system to withstand temperatures of up to 200°C without deformation. Precision machining of the cooling plates achieves tooth thicknesses and pitches down to 0.1 mm with a strict tolerance of ±50 μm, ensuring the accuracy of the internal flow channels and the entire cooling plate production. Advanced welding techniques also guarantee the stability of the cooling plates, so that neither deformation nor leakage occurs even under a pressure of more than ten atmospheres.
Testing : KAYTUS ensures the high safety and reliability of its liquid cooling systems through thorough, standardized production tests on the cold plates, nodes and rack servers. These include quick connection and disconnection tests, heat exchange tests, flow rate, airtightness, pressure release, drainage, drying and other critical processes. Each liquid cooled server undergoes comprehensive quality control to facilitate high volume shipment and delivery. All testing procedures are seamlessly and in real time integrated into the Manufacturing Execution System (MES), which uses 5G networks, cloud storage and advanced technologies to digitize and store test data while enabling product quality traceability.
Delivery: KAYTUS uses modularization and prefabrication concepts so that products can be delivered as prefabricated containers or modular data centers. This approach enables liquid-cooled data centers to be manufactured like building blocks, reducing construction cycles by over 50%. For example, the closed-loop piping network uses BIM design, where all valves and fittings are prefabricated in the factory and assembled on site. This prefabrication reduces construction time for this phase from one month to just one week. In addition, by deploying a range of smart sensors in advance, digital twins of liquid-cooled data centers are created based on accurate models, enabling advanced monitoring and operational efficiency.
