Stulz has launched a new coolant management and distribution unit (CDU).

The air conditioning specialist this week announced the launch of CyberCool CMU – a CDU designed to maximize heat exchange efficiency in liquid cooling solutions.

The company said CyberCool CMU offers “industry-leading levels of energy efficiency, flexibility, and reliability” within a small footprint, while providing precise control over an entire liquid cooling system.

The company is offering four models in two sizes. The system’s rated heat exchange is 345 – 1,380 kW. The rated water supply temperature for the facility water system is 32°C (89.6°F), while the rated liquid supply temperature for the technology cooling system is 36°C (96.8°F).

Comprising water pumps, plate heat exchangers, water valves, and controllers, the new CMU isolates the facility's water system (FWS) and technology cooling system (TCS) elements of a liquid cooling system to maximize heat exchange. Stulz said this also reduces the risk of cross-contamination and leaks, improving reliability.

“The rapid advancement of high-performance computing, artificial intelligence (AI), and machine learning (ML) has led to a massive increase in data center rack and server power density,’ said Joerg Desler, global director for technology at STULZ. “CPUs and GPUs are expected to exceed 1,000W per processor or higher in the next few years. These processing requirements are placing tremendous demands on data center cooling systems, and where liquid cooling was once an option, it is rapidly becoming essential.”

Stulz said the new CyberCool CMU is designed to integrate with ancillary STULZ A/C products, and helps support ASHRAE’s guidelines for water cooling specifications.

Stulz this week also announced it was partnering with Dutch immersion cooling firm Asperitas to develop a modular data center solution with integrated immersion cooling for indoor and outdoor installation. The result of the collaboration is a module offering IT loads up to 200kW in combination with immersion cooling technology from Asperitas.
