CHx500 CDU x4
Built to scale, CoolIT Systems’ CHx500 is the industry’s first modular liquid-to-liquid coolant distribution unit (CDU). Customers can add up to four (4) x 500 kW CDUs to increase cooling capacity to 2 MW within a single rack. The CHx500 CDU cools multiple high-density direct liquid cooled (DLC) servers and supports energy-efficient warm water cooling.
