Product Description

The 12-Slot 66kW Antminer Hydro Cooling Rack PLUS is built for miners who want the same compact 12-slot hydro cooling setup with a higher standard of hardware quality. It supports up to 12 Antminer hydro miners and brings cooling, miner mounting, power connections, and water lines together in one dedicated rack.

The PLUS version places more emphasis on build quality and component selection, making it a better fit for users who prioritize solid construction and dependable long-term operation. The rack keeps the installation clean and accessible, with the cooling and power systems arranged around the miners for easier inspection and routine maintenance.

For miners moving from a basic home setup toward a more organized operation, the PLUS provides a practical bridge between residential mining and professional rack deployment.

Core Advantages

01. Reinforced 12-Slot Rack Frame

This 12-slot rack features a black-coated reinforced frame. It centralizes 12 Antminer hydro units in one place, providing an organized structure for cable and hose management in home or workshop environments.

02. Industrial Stainless Steel Manifold

The 304 stainless steel manifold is built for long-term durability. It features precision-welded pipes and manual shut-off valves for each slot, ensuring balanced coolant flow and reliable leak-free hashing.

03. Organized Power Distribution Hub

The power management section utilizes automatic reclosing breakers for enhanced safety. This individual switch layout provides over-current protection and allows maintenance on specific miners without total downtime.

04. Integrated CDU Circulation Module

The integrated CDU module houses an industrial pump and a stainless steel expansion tank. It maintains stable fluid pressure and ensures the 66kW heat load is exported efficiently through the whole cooling loop.

05. Automated PLC Management System

The intelligent PLC system monitors real-time fluid pressure, temperature, and flow rates. It features automated speed regulation for fans and pumps, ensuring the whole rack maintains a constant thermal balance safely.

06. V-Type Corrosion-Resistant Cooler

This V-type cooler uses a corrosion-resistant aluminum tube-fin structure. Its anti-clogging design ensures stable heat exchange in environments with impurities or corrosive media reliably for long-term mining operations.

12-Slot Home Hydro Cooling Rack FAQs

Does 12 slots mean I can run any 12 Antminer Hydro miners?

Not necessarily. The system provides 12 physical miner slots, but the actual number of miners that can operate simultaneously depends on their combined power consumption.

The total miner load should remain within the system's 66kW capacity. For higher-power Hydro models, please confirm the total power consumption before deployment.

How is coolant flow distributed across 12 miners?

The system uses a centralized circulation loop and manifold to distribute coolant to each miner.

Proper flow balancing is important in a multi-miner setup to ensure every miner receives sufficient coolant. The system has a rated circulation flow of 6m³/h, while individual miner flow requirements depend on the specific Antminer Hydro model.

If one miner needs maintenance, do all 12 miners have to be shut down?

No. Individual miner branches can be isolated for inspection or maintenance without shutting down the entire cooling system.

This makes it easier to replace or service one miner while keeping the remaining miners in operation, reducing unnecessary downtime.

Why is a dry cooler recommended for a 12-miner system?

For a 12-miner deployment, a dry cooler offers a simpler and more cost-effective heat-rejection solution.

Compared with a closed cooling tower, it requires less supporting equipment and is easier to install and maintain. Closed cooling towers are generally more suitable for larger centralized mining deployments.

Can the system maintain cooling performance in hot weather?

Cooling performance depends on total miner load, outdoor temperature, coolant temperature, airflow, and dry cooler operating conditions.

The matched cooling system should be selected according to the site's maximum summer ambient temperature. For very hot regions, we recommend confirming the actual site conditions before finalizing the cooling configuration.

How much additional power does the cooling system consume?

The cooling system consumes additional electricity beyond the miners themselves.

Power is required for the circulation pumps, control system, and dry cooler fans. These auxiliary loads should be included when calculating the total electrical capacity required for the complete 12-miner installation.

How are all 12 miners monitored and managed?

The system uses PLC-based intelligent control and supports MODBUS-RTU communication.

Operating parameters such as system status, temperature, flow, and other cooling conditions can be monitored centrally, making it easier to manage a multi-miner Hydro installation and identify abnormal operating conditions.

What coolant and routine maintenance are required?

The system uses an ethylene-glycol-based cooling solution suitable for the installation environment.

Routine maintenance includes checking coolant quality and level, system pressure, flow distribution, pumps, valves, hoses, pipe connections, leaks, and keeping the dry cooler clean with unobstructed airflow.
