In-rack 16 kW liquid-to-air CDU
A 19-inch air-to-liquid CDU for single-rack GPUs and small workstations. Dual pumps, built-in leak and over-temperature protection, variable-frequency savings.
Built around the heat load, not around a rack size.
Engineered for edge micro-computing, this rack-mounted air-to-liquid CDU uses a standard 19-inch rack installation and a hybrid cooling system that combines air and liquid cooling. The unit integrates a circulation heat exchange module and uses a dual-pump redundancy design for stable operation and precise temperature control.
With its compact size and easy installation, it includes built-in leak and over-temperature protection and smart variable-frequency energy saving. Local touch control and remote monitoring are both supported, which makes it a natural fit for cold plate cooling in single-rack GPU and small workstation scenarios.
