Success story

CoolIT and Stäubli: delivering high-performance liquid cooling for next‑gen AI data centers

Powering the AI revolution: How CoolIT boosted efficiency and reliability with Stäubli connectors

The challenge

With the rise of AI and next-generation processors, data centers face unprecedented thermal loads. Traditional air cooling can no longer keep pace with these demands. To ensure performance, efficiency, and sustainability, liquid cooling has become a necessity—not an option. CoolIT recognized this shift and needed a fail-safe solution for quick, secure server integration within liquid-cooled environments.

The solution

The answer came in the form of dripless, quick-connect couplings, and Stäubli emerged as the clear choice to provide the safest and most-effective solution.

Stäubli's quick-release couplings feature a non-spill, flush-face technology that guarantees a perfect seal during use and the connection/disconnection phase.

The uncompromising tightness of Stäubli fluid connectors ensures clean, consistent performance to protect servers equipped with CoolIT’s Direct Liquid Cooling systems. Their compact design maximizes efficiency, making them ideal for high-density environments where space is at a premium.

THE PARTNER

CoolIT Systems, Inc., is the global leader in energy-efficient, liquid cooling solutions for data centers, servers and desktops with more than two million liquid cooling units worldwide.

THE END USER

GWDG is a leading scientific data and IT service organization supporting the University of Göttingen and the Max Planck Society. As a central IT competence center, it provides advanced computing, storage, and network services while conducting independent research in practical and applied computer science. Through its role operating high‑performance systems and managing key research networks, GWDG enables and strengthens research, teaching, and innovation across a wide range of scientific disciplines.

APPLICATION

Quick-release couplings for liquid cooling circuits.

The result

When GWDG needed a cooling solution that was efficient, reduced carbon footprint, and integrated seamlessly with their infrastructure, CoolIT partnered with Stäubli to make it happen. With next-generation AI processors demanding more power, liquid cooling connectors have become essential—transforming operations for the better.

By implementing Stäubli’s advanced connector technology, GWDG achieved:

 

  • Zero-leak connections to protect sensitive IT hardware
  • High flow with low pressure drop to support high-density AI workloads
  • Blind-mate capability for fast, secure, repeatable connections during maintenance
  • Proven reliability, validated by leading liquid cooling integrators and chip makers

 

This collaboration not only improved energy efficiency and reduced PUE but also made maintenance safer and easier. Today, Stäubli and CoolIT continue to deliver connector success stories across AI, HPC, and hyperscale data centers worldwide—with dedicated teams supporting projects in the United States, Europe, Taiwan, and China.

Confidence, Engineered Together

For CoolIT, uptime is non-negotiable. That’s why Stäubli’s quick-coupling technology connects their liquid-cooling systems, delivering the leak-free performance that lets CoolIT ensure reliability to every customer.

"What we value the most in Staubli’s products are the reliability, dripless performance, and low pressure drop even under demanding thermal loads."
