Liquid-to-Liquid Coolant Distribution Unit (L2L CDU), 1500 kW

Features & Benefits

Cost Effective

• Maximize energy saving: cuts power consumption, surpassing traditional air cooling
• Space optimization: compact design enables closer server placement further reducing Capex
• Flexible integration: supports direct-to-chip and Rear Door Heat Exchanger (RDHx) application, adapting to existing setups and blending air and liquid cooling for future upgrades

High Reliability

• Uninterrupted operation: dual power feed with ATS ensures continuous CDU operation
• Optimized redundancy design ensures no single point of failure in the system
• Leak detection: instant alarms with configurable response for efficient pumping action
• Durable construction: stainless steel plumbing with 50-micron filters for long-term coolant quality

Easy Management

• Intuitive interface: 10-inch color touchscreen displays real-time system status
• Efficient control: group and manual control enhance system management and reliability
