Coolant Distribution Unit AL-8
A 4U air-to-liquid CDU rated at 8kW for cold-plate liquid-cooled servers.
The AL-8 is a rack-mounted heat-exchange unit for ultra-high-density cold-plate liquid-cooled servers, with a rated cooling capacity of 8kW. Clamp-style connections simplify installation. Redundant pumps support reliable operation and straightforward replacement and maintenance. The system manages and distributes cooling capacity and includes comprehensive real-time operating-parameter monitoring with TCP/Modbus communication.
Key features
Intelligent flow control
Redundant pump motors use variable-speed control to adjust system flow in response to server load.
Real-time monitoring
Tracks exhaust-air temperature, supply-coolant temperature, supply and return pressure, and coolant flow.
Local operating display
A 7-inch touchscreen displays operating status, system alarms and self-test information and supports local operation.
