Liquid-to-Liquid CDU, SuperCDU-500

Liquid-to-Liquid Coolant Distribution Unit (L2L CDU)

The increasing demand for high-performance computing and advanced GPUs highlights the limitations of aircooling. Delta's SuperCDU offers a superior alternative, providing effective separation of facility and secondary circuits as well as precise control over flow, pressure, temperature, and coolant quality. It excels in managing high-density thermal load, maximizing computing power while minimizing data center PUE. The SuperCDU ensures operational reliability by preventing condensation and guarantees quality with its stainless steel plumbing and coolant filtration. Embrace the future of high-performance computing with Delta’s SuperCDU!
