Overview
At DCX, we understand the unique needs of hydro miners and direct liquid cooling systems. That’s why we offer a comprehensive range of cost-effective yet enterprise-class Coolant Distribution Units (CDUs) that are specifically designed to support advanced and power-hungry hydro miner models.
DCX CDU’s, or Coolant Distribution Units, are an essential component in direct chip cooling (DLC) or hydro cooling systems. These standalone, rack-based units play a crucial role in efficiently and adaptively cooling hydro miners while ensuring full condensation control. Including the in-rack CDU 1 & 2 models, as well as CDU 3, 6, 9, and 12 with a rated cooling capacity ranging from 300 to 1200 kW, DCX CDU’s offer effective separation of the coolant and the electronic components. They are responsible for monitoring the temperature of the coolant and adjusting the flow rate as necessary to maintain it below the dew point. This ensures that the precious electronics remain protected from condensation.
By providing precise temperature control and condensation prevention, DCX CDU’s contribute to the overall efficiency and reliability of DLC or hydro cooling systems. Their adaptive cooling capabilities enable them to meet the specific needs of hydro miners, allowing for optimal performance while safeguarding against potential damage caused by condensation.
Investing in DCX CDU’s is a smart choice for those seeking effective coolant distribution solutions for their direct chip cooling systems. With their advanced features and ability to maintain optimal operating conditions, these units offer peace of mind and enhanced performance for your valuable electronic equipment.
The main features of a DCX CDU include:
- A high flow rate ensures enough coolant supply for all components in the cooling loop.
- Remote monitoring includes temperature, flow, and operation sensors that alter the flow rate to ensure consistent coolant temperature.
- The cooling system is constructed with redundant pumps and components to provide continuous operation in case of failure.
- Energy efficiency: CDUs use variable speed pumps and innovative control systems to reduce usage.
Experience the difference with DCX’s advanced Coolant Distribution Units – designed for high-powered miners and engineered for success in the world of cryptocurrency mining.

CDU 2 InRack Cooling Distribution Unit
InRack 4U CDU, with 170 and even 200 kW heat transfer capacity at average 10°C – 15°C approach temperature and 300kW at approach temp claimed by competitive systems. Over 2 x more efficient than comparable in rack 4U CDU’s, will effectively cool more racks than any other 4U CDU. This rack based unit is equipped with 2 redundant multistage immersion pumps and can effectively cool multiple racks or high-powered HPC systems with 2 x higher pressure and flow rate than any other solution.
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.
Steel cover to prevent contamination, with spill prevention components.
All-steel enclosure big enough to house up to 400kg of dielectric fluid and miners. Building block for the rack or scale-out container installations. Enables high-temperature mining for the best heat transfer parameters. No more plastic boxes that can crack, leak or melt anytime, no more problems with temperature limits, no more problems with grounding.
L shaped frames to mount external components – switchgear, monitoring systems or PSUs. Placement of PSU outside of the immersion bath requires more retrofitting for the miners, but enables even bigger density and higher temperature for better heat exchange.
