CU423W1

The KAYTUS Coolant Distribution Unit (CDU) model CU423W1 is a core device in the liquid cooling system of data centers. It is responsible for coolant distribution, flow regulation and status monitoring. It connects the cold source and heat-generating equipment through components such as pipes, pump sets and valves to achieve precise cooling, energy consumption optimization and system safety management. Its key components adopt a redundant design to enhance system control and key parameter monitoring. Meanwhile, it supports top/bottom pipe outlet installation, featuring high reliability, intelligence and easy quick deployment, and is suitable for various cold plate liquid cooling data center scenarios.
