Overview
DCX provides a complete selection of cost-effective but enterprise-class Coolant Distribution Units (CDUs) designed specifically for hydro miners and direct liquid cooling systems, including complex and power-hungry hydro mining models. We provide a variety of CDU systems that are precisely engineered to fulfill individual needs, catering to both small-scale and large-liquid cooling applications.
Our options include the in-rack CDU 1 and 2 types, as well as CDU 3, 6, 9, and 12, with rated capacities ranging from 300kW to 1200kW per CDU system. These CDUs are designed mainly to support high-powered miners or mining servers. They have sophisticated features such as variable-speed pumps, thorough condensation control, cooling loop separation, redundant components, adaptive operation, energy-efficient cooling, and intelligent controls, which enable full system remote control.
DCX CDUs are freestanding, rack-based Coolant Distribution Units that serve a crucial role in both direct chip cooling (DLC) and hydro-cooling systems. These CDUs, with rated cooling capacities ranging from 300 to 1200 kW, provide adaptive and efficient cooling for hydro miners while maintaining complete condensation control.
Designed to regulate the flow and temperature of coolant, DCX CDUs guarantee that every component in the cooling loop receives an ample supply of flow to maintain the desired operating temperature. They also play a pivotal role in monitoring the coolant temperature, adjusting the flow rate as needed to keep the temperature below the dew point, and safeguarding precious electronics from condensation. DCX CDUs excel at effectively separating the facility circuit and secondary circuit. This feature enables regulated fluid quality, ensuring that cooling fluid volumes in a data center setting are maintained to a minimum. The fluid’s flow, pressure, and temperature are continuously monitored to ensure proper fluid quality maintenance.
Some of the key features of a DCX CDU include:
• High Flow Rate: Engineered to deliver a substantial coolant flow rate, ensuring that every component in the cooling loop receives a sufficient supply of coolant.
• Full Remote Monitoring: Equipped with temperature, flow, and operation sensors, it monitors coolant temperature and adjusts the flow rate as needed to maintain consistency.
• Redundancy: Designed with redundant pumps and other components, guaranteeing the cooling system’s continuous operation in the event of a failure.
• Energy Efficiency: CDUs are crafted for energy efficiency, incorporating features like variable-speed pumps and advanced control systems that work to minimize energy consumption.
Our Coolant Distribution Units are essential elements in the functioning of direct liquid cooling and hydro systems in data centers. They allow to maintenance of the optimum operating temperature, ensure dependability, and improve the cooling system’s efficiency.

System Build
CDU 1 InRack Cooling Distribution Unit
The In-Cabinet Coolant Distribution Unit (CDU) boasts a rated cooling capacity of 120kW. This system is capable of handling up to 80 servers, with adaptive energy usage of up to 2kW for two server racks. From 120 to over 150 kW of heat transfer capacity, allowing heat reuse at up to 60°C of return temperature. Designed to satisfy today’s most demanding requirements. It is a best high-efficiency heat exchanger on the market to regulate processor and component heat.
The system has a clamp connection for easy and quick installation. With the double pump redundancy design, replacement and maintenance are simple, ensuring great dependability. Maintenance can be performed without a shutdown in the case of a pump or power outage, or if the filter gets clogged. Furthermore, the system has a complete real-time monitoring feature for operating parameters. Its top computer connection interface includes two redundant RS485 ports and two redundant RJ45 ports, which use the default communication protocols Modbus RTU and Modbus TCP/IP.
