A compact distribution unit engineered for high-density computing, delivering high-efficiency heat exchange via the primary liquid loop.
Liquid-to-Liquid (L2L) CDU
- Introduction
- The Liquid-to-Liquid (L2L) CDU series offers a comprehensive range of standard capacities from 100kW to 1400kW. Designed with highly integrated piping and pump redundancy (single pump, N+1, or N+N configurations), the system fully supports automatic failover. Utilizing 25wt% Propylene Glycol (PG) as the secondary coolant, it serves as the critical infrastructure for data centers transitioning from traditional air cooling to advanced liquid cooling.

High-Reliability Pump Design: Equipped with dual or N+1 pumps for continuous circulation, supporting automatic failover in the event of a single pump failure. The system allows both local and remote configuration of operational parameters, featuring automatic data retention during power outages.
Compact & Flexible Footprint: The 150kW model features a standard 4U rack-mount design, maximizing rack space. The 680kW model has a highly compact footprint of just 1200 x 600 mm and is equipped with heavy-duty casters at the base, enabling flexible transportation via forklift or manual handling.
Easy Maintenance: The electrical control cabinet features a tiltable structure that can be easily lifted via hydraulic supports, providing ample operating space for quick and safe maintenance.
Cooling Capacity Range: Covers capacities from 100kW to 1400kW.
Operating Temp & Coolant: The operating temperature range for the secondary coolant is 10°C to 55°C.
Power & Communication: Supports 380–415V, 50/60Hz three-phase power supply. Communication interfaces include RS485 RTU Modbus and TCP/IP SNMP for seamless integration.
Ideal Environments: Perfectly suited for high-computing environments, including AI liquid-cooled computing pods, supercomputing facilities, and High-Performance Computing (HPC) centers.
