In-row 500 kW liquid-to-liquid CDU
A floor-standing plant for AI halls: 500 kW of exchange, DN65 primary, modular cabinet, parallel expansion, IP55.
Built around the heat load, not around a rack size.
This in-row CDU is a customised all-in-one liquid cooling distribution unit engineered for AI high-computing applications. It integrates a heat exchanger, circulation system and automated control system, which allows rapid on-site installation. A dual-pump redundancy architecture holds precise and stable temperature control.
Variable-frequency operation delivers high energy efficiency and lowers the data center PUE. The modular cabinet structure supports parallel expansion. A smart monitoring system and built-in multi-level leak and over-temperature protection cover the high-density heat dissipation scenarios found in AI computing and edge data centers.
