Liquid-to-Air (L2A) CDU

The Liquid-to-Air CDU (Coolant Distribution Unit) is a self-contained liquid cooling solution engineered for high-density AI servers, GPU clusters, HPC systems, and next-generation data centers. By combining a closed-loop liquid cooling circuit with an integrated air-cooled heat rejection system, it eliminates the need for external chilled water infrastructure, making liquid cooling deployment faster, simpler, and more cost-effective.

Unlike conventional liquid cooling systems that rely on facility chilled water networks, the  Liquid-to-Air CDU operates independently. It requires no cooling tower, no chilled water piping, and no raised floor, making it an ideal choice for retrofitting existing air-cooled data centers, edge computing facilities, AI training clusters, and small to medium-sized HPC environments.

Technical Specifications

Key Features

No External Chilled Water Required

The CDU features an integrated air-cooled heat exchanger that dissipates heat directly to the surrounding air, eliminating dependence on building chilled water systems.

Benefits include:

• Independent cooling operation
• Lower infrastructure investment
• Simplified installation
• Flexible deployment in existing facilities

Plug-and-Play Design

The Cabinet Air-Cooled CDU is factory-assembled and fully tested before shipment. The system integrates:

• Plate heat exchanger
• High-efficiency circulation pump
• Expansion tank
• Air-cooled condenser
• Intelligent PLC control system
• Temperature, pressure, and flow sensors
• Safety protection modules

Installation only requires power connection and liquid cooling piping to the server racks, significantly reducing deployment time.

Compact Cabinet Architecture

Designed as a standard cabinet solution, the CDU minimizes equipment footprint while simplifying data center layout.

Compared with traditional liquid cooling infrastructure, it eliminates:

• Complex chilled water piping
• Raised floor construction
• Extensive on-site mechanical installation
• Additional cooling plant equipment

The result is a cleaner machine room with faster implementation and easier maintenance.

Intelligent Monitoring and Control

The integrated control system continuously monitors critical operating parameters, including:

• Supply coolant temperature
• Return coolant temperature
• Flow rate
• System pressure
• Pump operating status
• Fan operating status
• Coolant level

Optional communication protocols include:

• Modbus RTU/TCP
• RS485
• Ethernet
• BMS integration
• Remote monitoring platform

This ensures stable, reliable, and intelligent operation 24/7.
