Electronics cooling Success story

Liquid Cooling Brings Big Benefits


Quick-release couplings for liquid cooling circuits.

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.


“There is no room for failure in our environment. The placement of Stäubli connectors in our overall liquid cooling design gives us the confidence we need to guarantee our solution for our customers.”
Geoff Lyon, CEO and CTO, CoolIT

The challenge: As they began architecting solutions for data centers, CoolIT recognized the myriad benefits of liquid cooling but were in need of a highly reliable, fail-safe mechanism to extract and install a server into an ecosystem that was liquid cooled.

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 unfailing tightness of Stäubli fluid connectors ensures the clean, consistent performance necessary to protect servers fitted with CoolIT’s Direct Liquid Cooling solutions, and the compact design maximizes efficiency, making them perfect for use in tight spaces.

The result: CoolIT has partnered with Poznan Supercomputing & Networking Center (PSNC), a multifunctional hub for internet networking services, research and development, and supercomputing resources in order to address heat loads within their data center, named Eagle. CoolIT now liquid cools more than 1,300 servers within Eagle, and the strength and reliability of Stäubli’s quick disconnects ensures there are no compromises. Eagle, originally ranking No. 79 on the global Top 500 Supercomputers Sites, is the second largest supercomputing installation in Poland. Because PSNC prides itself on being a leader in innovation, it is fitting that the warm water generated from the servers is transferred to their external heating system. The PSNC campus heating system is able to reuse the waste server heat and save energy.
