Overview

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.
