CDU32700 L2L 2700kW
CDU32700 L2L 2700kW
The 2700kW CDU is a liquid-to-liquid (L2L) Coolant Distribution Unit. It features dual plate heat exchangers for efficient heat transfer. Heat is transferred from the secondary-side coolant loop to the primary-side chilled water loop, delivering reliable cooling performance.
Key Features
| Key Feature | Details |
|---|---|
| Pump Redundancy | • The CDU features a 2+1 redundant circulating pump configuration with cyclic switchover. The system remains operational even if one pump fails. |
| Easy Maintenance | • The pumps feature a modular skid-mounted design for easy maintenance and replacement. • The filters feature a hot-swappable design, enabling tool-free maintenance without system shutdown. |
| High Cooling Capacity in a Compact Footprint | • A highly integrated piping layout reduces the footprint to just 1200×1200 mm (L×W). • The CDU delivers up to 2700 kW of cooling capacity at ATD = 4. • A single CDU supports cooling for up to 12 NVIDIA Vera Rubin NVL72 systems (220 kW each) or 18 NVIDIA GB300 systems (150 kW each). |
| Flexible Movement and Handling | • The CDU is equipped with integrated forklift slots at the base for easy handling and transportation. The base structure also enables flexible on-site positioning, simplifying installation and deployment. |
