The 35kW 6-Slot Hydro Cooling Rack is a compact hub specifically sized for 6 Antminer units. Its 35kW capacity matches standard domestic power limits while supporting heat recovery. Instead of wasting energy, the system repurposes mining heat to provide warmth for your garage, workshop, or small home sections during winter.
The quiet liquid loop replaces industrial fan noise, exporting heat through an organized, narrow footprint. By keeping all hoses and power cables tidy, the rack ensures a clean workspace and stable hashing performance with minimal maintenance.
For hobbyists starting with a few miners, this rack offers a practical and eco-friendly way to combine mining with domestic heating.
Core Advantages

With its compact footprint and quiet liquid cooling system, the cabinet can be installed in a bedroom, home office, or other indoor space. It keeps the miners enclosed and organized without the constant fan noise of traditional air-cooled equipment.

The stainless steel manifold uses individual manual valves for each mining slot. Precision welding and sealed connections help reduce the risk of leaks, while separate valves make it easier to isolate a single miner for inspection or maintenance.

The built-in pump maintains continuous coolant circulation between the cabinet and the external cooling system. The stainless steel expansion tank helps accommodate changes in coolant volume and keeps the system running smoothly during extended operation.

Power cables are routed neatly inside the cabinet instead of being left exposed around the miners. The integrated PDU provides independent circuit breakers, making each connection easier to identify and giving the 35kW system a cleaner and more manageable power setup.

The heating version uses a brazed plate heat exchanger to transfer mining heat into a separate heating circuit. This allows the recovered heat to be used for radiators or underfloor heating, turning a by-product of mining into useful heat.

The external dry cooler uses a corrosion-resistant aluminum tube-and-fin heat exchanger for efficient outdoor heat dissipation. Its expanded fin surface improves air-to-liquid heat transfer, while the separate outdoor design keeps heat away from the mining cabinet and indoor space.

"I live in a city apartment, so silence was my main requirement. I keep this 6-slot rack in my home office, and it is honestly quieter than a standard desk fan. Since all the heat goes through the water pipes to the outside unit, my room stays cool even when all miners are running at full power. It’s the easiest way to start mining at home."
— Tech Hobbyist, Berlin Home Site
"Setting this up in my workshop was very simple. I chose the heating version, and it now provides all the warmth I need for my workspace during the winter. It’s much more organized than my old air-cooled rigs—no messy wires or hot air blowing everywhere. The plate heat exchanger works perfectly with my existing pipes to save me a lot of money on utility bills."

How many Antminer Hydro miners can this cooling rack support?
It provides 6 miner slots and supports up to 6 compatible Antminer Hydro miners, as long as the total miner power does not exceed the system's 35kW maximum load.It provides 6 miner slots and supports up to 6 compatible Antminer Hydro miners, as long as the total miner power does not exceed the system's 35kW maximum load.
Which Antminer Hydro models are compatible?
It is designed for compatible Antminer S19 Hydro, S21 Hydro, and S23 Hydro series miners. Since power consumption varies by model, please confirm the total miner load before installation.
Can it run 6 high-power Hydro miners at the same time?
Yes, provided the combined power consumption of the 6 miners remains within the 35kW system limit. For overclocked miners or higher-power models, we recommend confirming the actual power consumption before ordering.
Why is the system paired with a 50kW dry cooler?
The mining rack supports up to 35kW of miner load, while the external dry cooler is rated at 50kW. The additional cooling capacity provides heat-dissipation margin and helps maintain more stable coolant temperatures when ambient conditions change.
What power supply is required?
The system requires a high-capacity three-phase electrical supply. The cooling cabinet is designed for 380–480V, 50/60Hz. Site voltage, available current, circuit protection, and the electrical requirements of the external dry cooler should be confirmed before installation.
What coolant should be used?
Pure water or properly treated soft water with suitable antifreeze and corrosion inhibitor can be used. The coolant should be selected according to local water quality and ambient temperature, especially in areas where freezing may occur.
Can the system be installed indoors?
The mining rack can be installed indoors in a suitable mining room, warehouse, garage, or equipment area. The external dry cooler should normally be installed outdoors or in a well-ventilated area where the heat can be discharged efficiently.
What regular maintenance is required?
Routine maintenance mainly includes checking coolant condition and level, inspecting hoses and pipe connections for leaks, checking pump operation and water flow, and keeping the dry cooler clean and free from dust or airflow blockage.
