Product Description

The Avalon water cooler is a compact water cooling cabinet designed for home and small-scale Bitcoin mining, supporting 12 Avalon A1566HA 2U water-cooled miners.

It integrates rack space, pump station, CDU, and control system into one energy-efficient hydro cooling solution, minimizing footprint while maximizing coolant circulation.

Certified with CSA and CE, this home water cooler enables safe and rapid deployment in indoor mining environments. The hydro cooler supports closed cooling towers and dry cooling towers, providing flexible liquid cooling solutions. As a reliable liquid cooler, it delivers stable performance and represents a best water cooler choice for compact ASIC mining setups.

Core Advantages

01. Silent Home & Office Integration

This integrated cabinet combines all essential components into a single unit for home or office use. It effectively reduces operational noise by replacing loud fans with a quiet liquid loop to save indoor space.

02. Dedicated 2U Rack with Individual Control

Designed with dedicated 2U rails for Whatsminer units, each slot features an individual power switch. This allows for maintenance on single miners without stopping the rest of the rack to ensure stable uptime.

03. Industrial Leak-Proof Connections

The internal manifold utilizes 304 stainless steel piping and industrial leak-proof connectors. This secure setup ensures a dry environment for your hardware by preventing fluid leaks during long-term operation.

04. Standardized CDU Module Function

The integrated CDU module includes an industrial-grade pump and expansion tank. It maintains stable fluid pressure and ensures the 120kW heat load is exported efficiently to the external radiator consistently.

05. Automated PLC Management Logic

The PLC management system provides real-time monitoring of fluid temperature and pressure. It automatically adjusts pump and fan speeds to maintain thermal balance, ensuring safe and efficient performance daily.

06. Flexible Dry Cooler or Tower Options

Users can choose between a dry cooler or a closed cooling tower as the external heat dissipation device. This allows the system to adapt to local water access and climate conditions for optimal performance.

12-Slot Avalon Hydro Cooling Rack FAQs

Is this cooling rack only designed for Avalon A1566HA miners?

No. The standard configuration is designed for Avalon A1566HA 2U Hydro miners, but the system can also be customized for other compatible 2U Hydro miners.

Rack layout, cooling connections, quick connectors, coolant distribution, and system configuration can be prepared according to the miner models used in your project.

Can this rack support overclocked 2U Hydro miners?

Yes. The system supports up to 120kW of total miner load and is suitable for high-performance and overclocked Hydro mining operation.

For Avalon A1566HA miners, standard operating power leaves additional system capacity that can be used for higher-performance operation while keeping the total miner load within the rack's 120kW design limit.

Can different 2U Hydro miner models be installed in the same rack?

Yes. Mixed-model deployment can be supported through customization.

If different compatible 2U Hydro miners are used in the same rack, the cooling interfaces, quick connectors, branch layout, and operating requirements can be matched before shipment. This is useful for mining farms that already operate more than one Hydro miner model.

Why is the system rated at 120kW if 12 Avalon miners use less power at standard settings?

The additional capacity provides useful headroom for overclocking, power variation, and high-load continuous operation.

Instead of designing the cooling system exactly around the miners' standard power consumption, the 120kW capacity gives operators more flexibility to increase performance without immediately replacing the cooling infrastructure.

Is 8m³/h enough coolant flow for a fully populated 12-miner rack?

Yes. The system provides a rated circulation flow of 8m³/h, while the specified minimum coolant circulation requirement is at least 0.6m³/h per miner.

For 12 miners, the combined minimum requirement is approximately 7.2m³/h, so the circulation system is designed to support a fully populated rack.

Are the cooling connections prepared before shipment?

Yes. The cooling interfaces and quick connectors can be prepared according to the selected 2U Hydro miners before shipment.

This reduces additional fitting and piping work during installation and allows miners to connect directly to the corresponding coolant supply and return branches once the rack arrives on site.

Does this 12-slot rack still include industrial control and safety systems?

Yes. Even though this is a 12-slot compact hydro cooling rack, it is still equipped with a full industrial-grade control and safety system.

The system includes a PLC-based control unit for real-time monitoring and automated operation management, as well as leak detection sensors to ensure safe operation of the liquid cooling loop.

These features allow the rack to maintain stable and secure operation even in small-scale deployments, without relying on external control systems.

What heat-rejection solution is recommended for this 12-slot system?

For a 12-miner deployment, a dry cooler is the recommended solution because it provides a simpler and more cost-effective cooling configuration at this scale.

The system can be matched with a 122.6kW dry cooler, avoiding the additional equipment and water-system complexity that usually makes a closed cooling tower less economical for smaller deployments.

When should I choose this 12-slot rack instead of a larger 20-slot system?

Choose the 12-slot system when your planned deployment is around 12 high-power 2U Hydro miners and you want a compact professional cooling solution with support for overclocking and miner customization.

If your near-term mining plan will exceed 12 units or approach a 200kW miner load, starting with a larger 20-slot system may provide a more suitable expansion path.
