Liquid-to-Liquid Coolant Distribution Unit
SmartSense CDU is a high-performance, rack-mounted liquid-to-liquid Coolant Distribution Unit designed to meet the rigorous demands of GPU-dense, high-power racks. Capable of cooling up to 300kW per rack or across neighboring racks, and over 2MW at the row-level, it effectively manages heat in power-intensive environments, ensuring your data center infrastructure remains optimized for next-generation workloads.
SmartSense CDU Features
- Ultra-efficient, redundant pumps operate at low speeds (2,900 RPM nominal, 3,600RPM max) for quiet, efficient, and reliable performance.
- Versatile rack design compatible with 42-inch+ (1070 mm) deep racks in the 19-inch or ORV3 form factors, enabling seamless integration into modern data centers.
- Automatic pump switching ensures uninterrupted operation in case of pump failure or error.
- Advanced cross-connected filtration delivers low-loss, ultra-clean fluid distribution for enhanced system efficiency.
- Ultra-low thermal loading for flow ensures more uniform device temperatures and extended device lifetimes (>1 LPM/kW). ASHRAE W4 and W+ compatible.
