The 154kW 28-Slot Hydro Cooling Cabinet is a professional unit designed for small-to-medium mining setups. It provides stable cooling for up to 28 Antminer hydro series units in a compact frame that keeps hoses and cables organized.
This model offers excellent thermal flexibility. Depending on your local climate and water access, you can pair the cabinet with either a dry cooler for waterless operation or a closed cooling tower for better performance in hot regions. This ensures your system remains efficient whether you are in an arid environment or a high-temperature area.
Built for practical use, this cabinet fits easily into garages or small workshops. It is a quiet, reliable, and low-maintenance liquid cooling solution for miners who need professional performance with a smaller, more adaptable footprint.
Core Advantages

Crafted with 304 stainless steel and meticulous hand-welded connections. Each joint is pressure-tested to ensure a leak-free system and superior structural integrity for long-term industrial mining.

Features organized industrial wiring and multi-level electrical protection. This structured layout prevents cable overheating and ensures stable power delivery to all slots for high-load 154kW operations.

Each slot has a dedicated, labeled circuit breaker. This "one-miner, one-control" design allows maintenance on individual units without disrupting the entire rack, significantly reducing system downtime.

The integrated CDU features a heavy-duty pump and specialized expansion tank. It maintains consistent fluid pressure and high flow rates to keep all 28 miners at optimal temperatures 24/7.

A moisture-sensing immersion rope is installed along the base to detect fluid presence. This essential safety layer prevents hardware damage by providing instant alerts if a leak is detected.

The intelligent system provides real-time monitoring of temperature, pressure, and flow rates. It features automated speed regulation for pumps and fans, ensuring peak energy efficiency and thermal stability.

Which miner models are compatible with this 28-slot rack?
This rack is specifically optimized for the Antminer Hydro series (such as S19 Hyd., S21 Hyd., and S23 Hyd.) and other standard hydro-cooled servers. Its compact frame is designed to keep hoses and power cables organized for a clean, professional setup.
Should I choose a dry cooler or a closed cooling tower for this system?
It depends on your environment. A dry cooler is ideal for arid regions as it requires no water. However, if you are in a high-temperature area, a closed cooling tower provides superior heat dissipation. We can help you select the best option based on your local climate.
What are the electrical and voltage requirements for the rack?
The system typically requires a 380V-415V three-phase power supply. Given the 154kW total cooling and mining load, we recommend ensuring your site’s transformer and main cables are rated for at least 170kW-180kW to provide a safe operating margin for continuous 24/7 operation.
Can I monitor the status of the rack remotely?
Yes. The intelligent management system supports data communication, allowing you to upload real-time parameters like temperature, flow rate, and pressure to a remote control center. This enables you to track the system's performance via PC or mobile device without being on-site.
Is this system suitable for installation in a home garage or small workshop?
Yes. The 28-slot rack is designed for a small-to-medium footprint and operates much quieter than air-cooled setups. Its organized internal layout and flexible external cooling options make it a practical choice for residential or small professional spaces.
