Asetek Achieves 200 Million Hours of Fault-Free Pump Operation at Data Center Installations

Asetek Distributed Pumping Architecture Provides Reliable & Cost-Effective Cooling

Asetek® (ASETEK.OL) today announced that its server pump has achieved 200 million hours of reliable operation in real world use. Installed at end-user locations as diverse as Singapore and Norway, Asetek pumps have run fault-free for the equivalent of 22,000 years.

“To date, we have not had a single server pump failure at any of our data center installations around the world,” said Mette Nørmølle, Vice President of Engineering.  “Our low-pressure architecture is the key to enabling a cost-effective solution that is relied on by data centers demanding unrivaled performance and maximum uptime.”

At the heart of Asetek liquid cooling is the Direct-to-Chip (D2C) CPU Cooler. The CPU Cooler is a patented integrated pump and cold plate assembly used to cool server CPUs. Because a single pump has sufficient power to circulate cooling water in a server node, servers with more than one CPU have multiple pumps, providing built in redundancy.

With over 3.5 million units deployed worldwide in desktop PCs and servers, Asetek’s cooler pumps incorporate features designed to meet our customers’ strict demands for reliability, performance and uptime. Pumps are mechanically sealed with the impeller, the only moving part, suspended in lubricating cooling liquid. As a result, high reliability and low cost are both inherent in the pump design.

Asetek’s reliable data center solutions include RackCDU D2C™ and Server Level Sealed Loop (ServerLSL™). RackCDU D2C provides cooling energy savings greater than 50% and density increases of 2.5x-5x. ServerLSL provides liquid assisted air cooling for server nodes, replacing less efficient air coolers and enabling the servers to incorporate the highest performing CPUs and GPUs.

Asetek liquid cooling is currently available to data centers around the globe through its network of OEM partners.
