Product Description
The 70kW 12-Slot Home Water Cooler is designed for running multiple Antminer hydro miners in a residential environment without bringing the typical heat and noise of a mining room into your living space. It supports up to 12 Antminer hydro units with dedicated liquid cooling for home mining setups.
The system is suited to garages, workshops, basements, and other spaces where power and room size matter. Its water cooling loop moves heat away from the miners while providing quiet operation, helping keep the surrounding area more comfortable during continuous mining.
For home miners, it offers a straightforward way to run more machines in the space they already have. An optional heating version is available to reuse mining heat for space heating instead of simply releasing it.
Core Advantages
01. Compact Home Integration
This integrated cabinet houses 12 Antminer hydro units in a compact footprint. Designed for home use, it keeps all miners organized and protected while fitting perfectly into residential or workshop spaces easily.
02. Independent Leak-Proof Manifold
Hand-welded 304 stainless steel manifold with manual valves. This system ensures balanced flow to all 12 miners while preventing leak risks, providing a secure setup for your home or workshop floors perfectly.
03. Industrial-Grade CDU Module
The integrated CDU includes a heavy-duty pump and expansion tank. It maintains stable pressure and flow, ensuring 70kW of heat dissipation while keeping the system running quietly and efficiently at all times.
04. Safe Residential Power Management
Engineered for home safety, the PDU features industrial-grade wiring and individual circuit breakers. This setup provides over-current protection and allows easy maintenance without shutting down the entire rack.
05. Optional Fan Speed Controller
Optional Fan Speed Controller for customized thermal management. This non-standard add-on allows manual adjustment of fan speeds to balance cooling performance with noise levels based on your home environment.
06. High-Efficiency External Cooling
The external dry cooler utilizes an integrated water curtain for auxiliary cooling. This system ensures high-performance heat rejection even in peak summer, maintaining stable hashing for all 12 miners reliably.

"The silence of this 70kW setup is its biggest advantage. I have six units running in my garage, and my neighbors can't hear a thing. It keeps the whole installation looking like a professional server room rather than a messy mining rig, which was essential for staying compliant with our local residential noise rules."

"Installing this 12-slot rack completely organized my basement setup. The build quality of the manifold is top-tier, and my Antminers finally run at a constant temperature regardless of the weather outside. It’s the most efficient way to scale a home operation without turning your living space into an industrial zone."

12-Slot Home Hydro Cooling Rack FAQs
What is the total power capacity of the H12 cooling cabinet? Can I run it on a standard residential grid?
The total design power load of the H12 cabinet ranges from 70 kW.
- Grid Requirements: Running 12 units of the latest Hydro miners (e.g., Antminer S21/S23 Hydro, which consume ~5.4–5.6 kW each) requires a total of approximately 65 kW. Standard residential single-phase outlets cannot handle this load. You must have a stable Three-Phase Industrial Electricity supply (e.g., 380V–415V). Please verify your local breaker capacity before purchasing.
Are the PDU and power cables pre-integrated into the cabinet?
Yes, the H12 comes standard with an integrated industrial power distribution enclosure and a 12-channel hydro-specific PDU system. All power cables are perfectly sized for seamless plugging.
Safety Warning: Proper grounding (earthing) is strictly mandatory for both the cabinet frame and the power inputs to ensure absolute safety against static buildup or current leakage in liquid environments.
How loud is the 12-slot cabinet in real-world operation? Can I place it in a garage or basement?
- Indoor (The Cabinet): Extremely quiet. The cabinet itself generates only ≤ 50–55 dB of sound—mostly subtle humming from the water pumps and minor auxiliary chassis fans.
- Outdoor (The Dry Cooler): The heat is dissipated via the external Dry Cooler. It utilizes large-diameter, low-RPM silent fans. This completely eliminates the deafening, high-pitched scream of traditional air-cooled fans.
- Recommendation: It is perfect for basements, detached garages, or small workshops, provided the external Dry Cooler is placed in a well-ventilated outdoor space.
What are the dimensions of the cabinet? Will it fit through a standard doorway?
The H12 is engineered specifically with a compact "server rack" footprint. It occupies less than 1.5 to 2 square meters of floor space and stands roughly 1.6 to 1.8 meters tall. It is fully capable of fitting through standard residential doorways and service elevators without disassembly.
Can I connect the water system directly to standard tap water?
- No, absolutely not. Tap water contains minerals that will quickly create scale and buildup inside the miner's cooling plates and the heat exchangers. This will cause temperatures to skyrocket and permanently fry the ASIC chips.
- Coolant Specification: The internal loop must use Deionized Water or ultra-pure distilled water.
- Cold Climates (Below 0°C / 32°F): You must blend the water with specialized antifreeze (or high-purity propylene glycol) to prevent the internal pipelines from freezing and cracking during unexpected downtime.
What are the financial advantages of upgrading to the H12 instead of building an air-cooled mining room?
- Zero Summer Throttling: Air-cooled miners automatically underclock or shut down entirely when ambient temperatures cross 35°C (95°F). The H12 maintains a rock-solid 60°C chip temperature, unlocking 365 days of maximum hashrate yield.
- Lower PUE (Power Efficiency): The combined power overhead of the water pumps and the external Dry Cooler is significantly lower than running 48 high-speed, high-wattage violent fans from 12 air-cooled rigs. This yields an instant 5% to 8% savings on your monthly electric bill.
- Maximum Resale Value: Operating in a fully sealed hydro cabinet keeps your miners completely free from dust, humidity, and atmospheric oxidation. When you decide to upgrade your hardware in 3 years, your miners will still look brand new, securing premium secondary market valuation.
