STULZ unveils CyberCool CMU for efficient data centre cooling

STULZ, a global specialist in mission-critical air conditioning solutions, has introduced its latest innovation, the CyberCool CMU, designed to enhance the efficiency of liquid cooling systems. Set to make its debut at Data Centre World Frankfurt 2024, CyberCool CMU is poised to offer unprecedented levels of energy efficiency, flexibility, and reliability, all while maintaining a compact design and delivering precise control across an entire liquid cooling system.

Joerg Desler, Global Director Technology at STULZ, highlighted the increasing demands on data centre cooling systems driven by advancements in high-performance computing, artificial intelligence (AI), and machine learning (ML). Desler noted that CPUs and GPUs are expected to exceed 1000W per processor in the near future, making efficient cooling solutions increasingly critical.

CyberCool CMU seeks to address these demands by optimising heat exchange within liquid cooling systems. It achieves this by isolating the facilities water system (FWS) from the technology cooling system (TCS), which significantly mitigates the risk of cross-contamination and leaks, thus enhancing overall system reliability.

STULZ's new product also provides precise control over variables such as coolant flow rates, temperatures, and pressure, thereby improving system efficiency. The unit is engineered to accurately manage the supply temperature and flow rate of the coolant with minimal power consumption. Its robust construction includes premium grade water pumps, plate heat exchangers, water valves, and controllers, all contributing to a reliable and efficient liquid coolant supply.

The quality of the liquid coolant is maintained through the use of sanitary grade stainless-steel pipelines. The CyberCool CMU also offers a range of structural, electrical, and control options, ensuring compatibility with specific customer configurations and power loads. Moreover, the unit can be customised to meet various needs within the dynamic liquid cooling (DLC) market.

In response to growing sustainability pressures, STULZ designed CyberCool CMU to integrate with ancillary STULZ A/C products, supporting ASHRAE's guidelines for water cooling specifications. The unit's software and hardware are harmonised for optimal reliability and usability, featuring an intuitive touchscreen display for straightforward menu navigation. Multiple variable speed pumps are included to adjust to required liquid flow rates, contributing to energy efficiency and providing built-in redundancy.

Joerg Desler expressed confidence in the product's potential to meet the expanding heat transfer demands of data centres. He emphasised that the transition to liquid cooling is well underway and that CyberCool CMU can deliver sustainable, efficient, reliable, and flexible solutions. Attendees of Data Centre World Frankfurt 2024 will have the opportunity to experience the CyberCool CMU firsthand and interact with STULZ experts.
