680kW/48U
680kW/48U
The 680 kW CDU is a liquid cooling unit that removes heat generated by equipment through the secondary-side heat exchange via a plate heat exchanger, and transfers the heat away through the primary-side chilled water loop.
Key Features
| Technical Parameter | Value / Details |
|---|---|
| Pump Redundancy | Adopts an N+1 pump configuration with cyclic switchover, ensuring continuous operation in case of single pump failure. |
| High Cooling Capacity In a Compact Footprint | Features a highly integrated piping design, with a footprintof only 1200 x 600 mm （LxW）, and is capable of removing up to 680 kW of heat. |
| Easy Maintenance Access | The electrical control cabinet adopts a tiltable structure. During maintenance, such as removing filter elements orreplacing pumps, the cabinet can be lifted via hydraulic supports, providing sufficient operating space. |
| Flexible Movement and Handling | Equipped with four heavy-duty casters at the base. The bottom structure allows for forklift handling for easy loading, and also enables flexible movement on the floor for convenient repositioning. |
