It consists of water pumps, heat exchangers, fans, filters, expansion tanks and control modules. The built-in circulating pump provides power for water circulation, carrying away heat from liquid-cooled servers, which is then dissipated into the environment by the fans.","working_principle":"","features":["Standard 10U rack-mount chassis","All stainless steel piping","High-efficiency centrifugal pumps with automatic flow adjustment","Redundant pump drivers with 1+1 cold standby","Active anti-condensation function","4.3-inch LCD control screen","Built-in leakage detection and automatic liquid replenishment","Constant differential-pressure or constant-flow output","Integrated monitoring","Dual power supply","Modbus RTU and TCP\/IP support"],"applications":["High-density data centers","Retrofit and new-build data centers","Intelligent computing centers","Large-scale computer rooms","AI training clusters","High-power industrial equipment cooling","Scientific research laboratories"],"notes":["Slide 4 labels the product Air-to-Liquid, but its CDU-35LJ \/ CDU-80LJ \/ CDU-100LJ reference table specifies both primary and secondary liquid circuits, while the description specifies fan heat rejection.
