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. | Technical Parameters Product Specifications Complete technical data for the 680kW/48U L2L In-Row CDU. | Parameter | Result | |---|---| | **TECHNICAL PARAMETERS: 680KW / 48U / L2L CDU** | - | | Technical parameters | 680kW / 48U / L2L CDU | | Rated cooling capacity | 680 kW @ 4.0°C ATD | | Maximum flow rate – single pump operation | 700L/min, external pressure difference 2.0bar | | Maximum flow rate – dual pump operation for N+ redundancy | 1050L/min, external pressure difference 3.4bar | | Secondary coolant type | Pure Water or PG25 | | Pump redundancy | Single pump (N) / dual pump (N+N) / dual pump switchover | | Primary pressure drop | 0.8 bar (PG25) under typical conditions (650 L/min) | | Secondary coolant temperature range | 10–55°C, with dew point control standard | | Maximum power consumption | 4.5 kW (Single Pump) 7.3 kW (Dual Pump) | | Dimensions (H × W × D) and weight | 1900 × 600 × 1050 mm, 550 kg | | Noise level at 3m (10ft) | < 54 dBA | | Power supply (Europe, Asia and Taiwan) | 3P 380-480 V 50/60 Hz | | Dual power supply (ATS) | Optional features | | Primary connections | Top or bottom, 2½-inch sanitary flange | | Secondary connections | Top or bottom, 2½-inch sanitary flange | | Secondary filtration | Optional 50um/20um | | Communication | RS485 RTU modbus, TCP/IP SNMP | Scroll to view all parameters ### Related Content #### Related Products - [150kW/4U](https://www.gerchamp.com/en-US/products/150kw-4u-2-2-2) ([Agent MD](https://www.gerchamp.com/en-US/products/150kw-4u-2-2-2/raw.md)) - The 150 kW 4U CDU is a compact liquid cooling core unit installed in a standard 19-inch server rack, with a height of 4U.
