COOLANT DISTRIBUTION UNIT
In-Row Liquid-to-Liquid CDU
A liquid-to-liquid Coolant Distribution Unit (CDU) in a data center is a specialized system crafted to oversee the distribution of liquid coolant within a closed-loop liquid cooling infrastructure. Unlike liquid-to-air CDUs, which utilize heat exchangers to transfer heat from IT equipment to the air, liquid-to-liquid CDUs facilitate direct heat transfer between liquid coolant circuits.
DeepCoolAI offers in-row L2L CDUs up to 2.5MW capacity.
