300 kW AALC CDU

Overview The Cooler Master 300 kW AALC (Air-Assisted Liquid Cooling) CDU offers high-heat-load management for IT hardware, dissipating up to 300 kW of thermal energy. This system delivers exceptional energy efficiency through its innovative design, ensures operational reliability with robust components, and offers flexible deployment options suitable for various modern IT environments. The system architecture features two V-patterned radiators and eight hot-swappable fans per rack, enabling efficient heat exchange with an approach temperature difference from 3 to 5°C. This liquid-to-air CDU is designed for deployment in existing data centers without built-in liquid cooling infrastructure. It is fully compatible with current GB200 and GB300 GPU server racks, as well as future VR200 systems.
