Coolant Distribution Unit AL-6
A 4U, 6kW air-to-liquid CDU with redundant variable-speed pumps and PLC-based monitoring.
The AL-6 is a rack-mounted heat-exchange unit for ultra-high-density cold-plate liquid-cooled servers. Its rated cooling capacity is 6kW. Clamp connections simplify installation, while redundant pumps support reliable operation and maintenance. The system manages server cooling and cooling-capacity distribution, with comprehensive real-time parameter monitoring. Redundant RS485 and RJ45 communication interfaces use Modbus RTU and Modbus TCP/IP by default.
Key features
Intelligent flow control
Redundant pump motors use variable-speed control to adjust system flow in response to server load.
System monitoring
PLC control integrates monitoring of temperature, flow, pressure, leakage and liquid level.
Intelligent alarms
A three-level alarm mechanism helps operations staff locate system abnormalities quickly.
