Customer Applications

Fujitsu: Precision at Scale

Chosen by Fujitsu for the record-breaking Fugaku supercomputer, Stäubli’s CGD quick-release couplings deliver leak-free, high-flow cooling performance at massive scale. With over 150,000 processors operating continuously, Fugaku relies on Stäubli’s proven reliability and global expertise to maintain uptime and efficiency across 400 racks and 384 connection points each.

CoolIT: Reliable and Efficient

When CoolIT designed critical liquid-cooled servers, reliability was nonnegotiable. Stäubli’s dripless, quick-connect couplings provided the leak-free seal and high performance they needed. Today, more than 1,300 servers at Poland’s PSNC Eagle supercomputer run on CoolIT and Stäubli technology, delivering safe, efficient cooling that’s easy to implement and maintain.
