Case Study: Preventing coolant backflow in supercomputers

Supercomputer

Equipment used	Spring-Disc Check Valves CK3 Series

Problem

As data center construction continues to expand worldwide, cooling systems are transitioning from air cooling to liquid cooling due to its high efficiency and energy-saving performance. This trend is especially pronounced in high-performance computing systems such as supercomputers, where large amounts of heat must be effectively removed to maintain stable performance.

However, if problems occur in the coolant circulation loop, heat cannot be sufficiently dissipated. This may cause processors and other components to overheat, potentially leading to low performance or even a system-wide shutdown.

“Supercomputers” Supercomputer

Solutions

Compact check valves with a simple structure, excellent durability, and high sealing performance help prevent coolant stagnation and backflow and can be installed vertically or horizontally.
This allows for a more compact piping design, making it possible to install the piping within the computer chassis.

Preventing cooling water backflow in supercomputers

Key Improvements

Prevents coolant stagnation and backflow, helping avoid performance issues and system-wide shutdowns caused by overheating due to circulation problems.
Helps reduce the installation space required for computer systems in data centers, where hundreds of units may be deployed.

Case Study: Incorporating into equipment for simple, compact configuration

Water purification system, SIP processes

Equipment used	Spring loaded disc-type check valves CK3 series

Problem

In addition to water piping, water purification equipment requires piping for steam used for sterilization, which is complex to handle and requires space. The site would like to maintain the equipment/plant size, even if a steam sterilization process is added to the equipment.

Solutions

Utilization of check valves with high sealing performance, compact size, and flexible vertical and horizontal installation.
This allows the piping to be designed compactly, and the size of the equipment and plant can be maintained.

Key improvements

CK3 is made of stainless steel and suitable for pure water applications
CK3 has excellent sealing performance and can eliminate the need for a manual valve for disconnection.
CK3 is compact and can be installed horizontally or vertically, allowing for greater flexibility in piping routing
