Product Description
Designed for flexible Avalon 2U hydro mining deployments, this 20-slot 200kW split-type hydro cooling rack provides a scalable foundation for customized mining infrastructure.
The separated rack and heat dissipation configuration allows the cooling system to be arranged according to available space, site conditions, and project requirements. Its modular architecture supports customized CDU capacity, pump configuration, and heat rejection equipment, making it easier to match different cooling loads and deployment plans. The system can also be expanded with additional cooling or supporting equipment as mining capacity grows.
Suitable for warehouses, indoor facilities, and phased mining projects, it provides a flexible approach to building and upgrading hydro-cooled mining infrastructure.
Core Advantages
01. Integrated All-in-One Design
The rack, CDU, power cabinet, and controller are all built into one single cabinet. Once delivered, simply connect the water pipes and power cables to start running—no complex assembly required.
02. Leak-Proof Valve System
High-seal manifolds and reinforced pipes prevent coolant leaks at the source. Red and blue valves control hot and cold water; simply turn them off to isolate lines during maintenance with zero spills.
03. PDU Individual Breakers
The PDU power panel features a 1-to-1 breaker design, giving every single miner its own dedicated switch. If one unit needs servicing, just trip its specific breaker without affecting the rest of the rack.
04. Bottom Water Leak Detection
A water-sensing rope is installed along the bottom edge of the cabinet. If coolant leaks to the floor, it triggers an instant alarm so onsite staff can fix it before any miners get damaged.
05. Durable Fittings & Solid Build
Features 304 stainless steel manifolds, industry-standard aviation plugs, and reinforced high-pressure tubing with manual ball valves. Solidly sealed and durable for long-term use.
06. Customizable & Expandable CDU
The CDU shown is fully customizable and expandable. We can adjust its cooling capacity, pump specs, and expansion ports based on your specific site conditions, miner count, and heat rejection equipment.
Modular 1-to-N Infrastructure Scalability
The 1-to-N modular design enables flexible power expansion from 200kW up to 1,000kW, allowing mining sites to scale based on evolving demand. Featuring a customized high-flow pump system and a dedicated power control cabinet, this solution ensures reliable management across multiple racks—eliminating the need for major infrastructure overhauls as your hashrate grows.

"Deploying two separate 1-to-1 systems was a practical choice for our site. Since each 20-slot rack has its own dedicated CDU and radiator, we have complete redundancy. If we need to perform maintenance on one loop, the other rack continues to hash without any interruption. It’s a very reliable way to manage our 2U hardware."
— Infrastructure Lead, Oman Mining Site
"The 1-to-5 configuration allowed us to scale our hashrate quickly while keeping the warehouse organized. The customized high-flow CDU maintains perfect water pressure across all 100 miners. Having a dedicated power cabinet for the whole cluster makes electrical monitoring much easier and safer for our technicians."

20-Slot Avalon 2U Modular Hydro Cooling Rack FAQs
Can this rack run 20 Avalon A1566HA Hydro miners at the same time?
Yes. The rack is designed for up to 20 Avalon A1566HA Hydro miners and provides up to 200kW of installed miner capacity.
For example, the A1566HA 500T is rated at approximately 8.064kW per miner, so 20 units require about 161kW at rated power. This keeps a fully populated rack comfortably within the 200kW system capacity.
Why is the rack rated at 200kW when 20 A1566HA miners use less than 200kW?
The additional capacity provides operating headroom rather than sizing the cooling infrastructure exactly to the miners' nominal power.
This gives the system more flexibility for different A1566HA versions, normal power variation, and continuous high-load operation while avoiding a design that operates permanently at its maximum capacity.
Can different A1566HA versions be installed in the same rack?
Yes. Compatible A1566HA Hydro versions can be installed together in the same 20-slot rack.
For example, the 500T and 460T versions use the same 2U-sized chassis dimensions, while their rated power differs slightly. This allows operators to replace or add miners without requiring every slot to use exactly the same hashrate version.
Is 11m³/h enough coolant circulation for all 20 miners?
Yes. The CDU provides a rated flow of 11m³/h, while the cooling system specifies a minimum circulation requirement of 0.5m³/h per miner.
Twenty miners therefore require a minimum combined branch flow of approximately 10m³/h, and the system is designed around this full-rack circulation requirement.
How does the system keep coolant flow stable across 20 parallel miner branches?
The CDU uses PLC-based constant-flow control together with centralized circulation and pressure management.
Rather than relying only on a fixed pump output, the control system monitors operating conditions such as coolant flow, temperature, and pressure to support stable circulation as the rack operates under changing load conditions.
Does every 20-miner rack need its own CDU?
No. The split-type architecture supports both standalone and multi-cabinet configurations.
For larger projects, CDU capacity can be customized so multiple Avalon cooling racks share centralized cooling infrastructure. This reduces duplicated equipment and makes it easier to expand from a single 200kW rack toward a larger mining system.
Can I start with one Avalon rack and expand the cooling system later?
Yes. The system is designed for modular expansion from approximately 200kW up to 1000kW.
If future growth is planned from the beginning, the CDU, main piping, heat-rejection equipment, and monitoring infrastructure can be sized for additional racks, allowing mining capacity to be added without redesigning the entire cooling architecture.
When is this rack a better choice than building a custom cooling loop for Avalon miners?
This rack is a strong choice when you want a standardized 20-miner deployment instead of separately designing the manifold, circulation system, controls, electrical cabinet, and external heat-rejection system.
The rack, intelligent CDU, PLC control, and optional dry cooler or closed-loop cooling tower are designed as one coordinated cooling architecture, reducing the amount of engineering that must be completed separately on site.
