Overview

DCX offers a full range of cost-effective but enterprise-class Coolant Distribution Units (CDUs) for hydro miners and direct liquid cooling systems that support advanced and power-hungry hydro miner models. We propose multiple CDU systems designed to fulfill specific requirements from small scale to large liquid cooling operations, including the in-rack CDU 1 & 2 models, as well as CDU 3, 6, 9, and 12 with a rated capacity from 300kW to 1200kW per single CDU system. These CDUs are designed for high-powered miners or mining servers and offer advanced features such as variable-speed pumps, full condensation control, cooling loop separation, redundant components, adaptive operation, energy-efficient cooling & intelligent controls with full remote control of the system.

DCX CDU’s, are standalone, rack-based Coolant Distribution Units (CDU), a key component in direct chip cooling (DLC) or hydro cooling systems. Those CDU’s with a rated cooling capacity from 300 to 1200 kW offer adaptive and efficient cooling of hydro miners with full condensation control. The CDU’s are designed to regulate the flow and temperature of the coolant and ensure that each component in the cooling loop receives an adequate supply of flow to maintain the desired operating temperature. It is also responsible for monitoring the temperature of the coolant and adjusting the flow rate as necessary to maintain the temperature below the dew point protecting the precious electronics from condensation. DCX CDU’s provide effective separation of the facility circuit and secondary circuit which allows controlled fluid quality and ensures that the cooling fluid in a data center environment can be kept to a minimum volume, is closely controlled for flow, pressure & temperature, and can be accurately maintained for fluid quality.

Some of the key features of a DCX CDU’s include:

  • High flow rate: designed to deliver a high flow rate of coolant to ensure that each component in the cooling loop receives an adequate supply of coolant.
  • Full remote monitoring: contains temperature, flow, and operation sensors that monitor the temperature of the coolant and adjust the flow rate as necessary to maintain a consistent temperature.
    Redundancy:  designed with redundant pumps and other components to ensure that the cooling system remains operational in the event of a failure.
  • Energy efficiency: CDU’s are designed to be energy-efficient, with features such as variable speed pumps and advanced control systems that help to minimize energy consumption.

Overall, our Coolant Distribution Units play a critical role in the operation of direct liquid cooling systems and hydro systems in data centers, helping to maintain the desired operating temperature and ensure the reliability and efficiency of the cooling system.

CDU 12 InRow Coolant Distribution Unit

Supercomputer class Coolant Distribution Unit with, 1200kW of heat transfer capacity at average 10°C – 15°C approach temperature. A supercomputer class CDU system which will support an astonishing number of over 1000 servers.
This unit is designed for high density servers cooling and offer advanced features such as variable-speed pumps, full condensation control, cooling loop separation, redundant components, adaptive operation, energy-efficient cooling & intelligent controls with full remote control of the system.
CDU 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. With the double pump redundant design, replacement and maintenance does not interfere with high availability of the system. Maintenance can be performed without downtime as all critical components are redundant.

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.
IP40 switchgear box for 10-12 3-4kW miners. Contains: 10-12 x overcurrent protection, circuit breaker, cable fittings, terminal blocks, cabling. We use top class Schneider, Eaton, Legrand or Siemens components.

ThermaSafe R™ Dielectric Engineered Fluid Best priced, 2 times better than recognized Bitcool BC-888 ASIC miner dielectric coolant. Dielectric, odorless, non-toxic, non-allergenic, long-life, eco friendly and safe HTF (Heat Transfer Fluid). Designed specifically for crypto mining operations, compatible with most ASIC, GPU and electronic equipment.
Filling kit. Flexible miners require more effort on fluid control. We want all the fluid to go through the miners not around. To enable a higher pressure drop around the miners we deliver filling kits which direct the fluid through the miners.

Sustainable high performance computing

As computing power constantly increases, liquid cooling becomes a necessary solution to replace conventional air cooling. DCX HYDRO stands out as the most powerful, compact, sustainable, and energy-efficient data center cooling technology available today.

Features & Competitive Advantages

More performance, better reliability, and more comfort. Nothing is better.

Flexible system supports all crypto mining hardware

Standard UNI Enclosure is capable of supporting crypto mining hardware such as GPU rigs and ASIC miners. Each Universal ILC Enclosure can hold 6 GPU rigs with up to 12 GPUs each, or 18 conventional S9, Z9, and A9 ASIC miners. The result is in 72 GPUs and 18 miners in a single UNI enclosure. Stacking enclosures to a 2/3 level stack produces 216 GPUs or 54 miners in less than 1 square meter. It’s the best you can get!

More performance. Less to pay.

The numbers are impressive: 30% of reduced electricity bills with a PUE of 1.05, most of the fans can be eliminated, and the system cools miners as well as power supplies. Liquid cooling systems enable overclocking and fine modifying with customized firmware, resulting in 20% higher hash rate through hardware and software optimization. Most users also benefit from stability, which increases their shares by up to 10%.

Plug and Mine

Ready to use and equipped with everything needed, the “plug and mine” option is ideal for those venturing into professional mining with 2-3-4 miners or mining rigs. The UNI Enclosure also serves as a pivotal component for scaling up solutions, accommodating 10-20-40 enclosures in our customized racks. Whether it’s a single UNI enclosure or an entire rack system, everything is provided. It performs flawlessly even in hot weather with high ambient temperatures, allowing for mining practically anywhere low-cost energy is available, with no failures or downtimes. And the best part? Setup takes minutes, not weeks.

Silent, low profile mining

One ASIC miner generates noise at 75dB continuously throughout the day and night. With a small farm of 2-4 rigs or ASIC miners, it becomes unbearable 24/7. A specific location is necessary. Miners must be spaced out and situated in a relatively cold area. Air must be filtered and vented, leading to expenditures on fans, air conditioning, location, and filters. With our immersion liquid cooling system, you will be able to mine quietly from your place or an area with the most convenient power source. Placing 48 GPUs or 10 ASIC miners in a box with dimensions less than 70x60x60 solves all these problems. Simple as that.
