Product Description
The Bitdeer SealMiner A4 Ultra Hydro is the flagship hydro-cooled ASIC miner in the A4 series, designed for high-performance Bitcoin mining. Delivering up to 886 TH/s at 8,372.7 W with a rated efficiency of 9.45 J/TH, it sets a new standard for energy-efficient, large-scale mining.The 2U form factor allows easy integration into modern data center racks, maximizing space utilization and operational efficiency.
Key Features
Strategic Efficiency – Breaks the 10 J/TH barrier with 9.45 J/TH, providing strong energy efficiency and long-term profitability.
High Hashrate Performance – Consistent 870–900 TH/s ensures reliable mining even as difficulty rises.
Silent Hydro-Cooling – Advanced liquid-cooling system minimizes fan noise for a quieter, stable mining environment.
Optimized Rack Density – 2U form factor (482 × 665 × 86 mm) maximizes deployment density and lowers operational costs per TH.
Efficient Power Management – Supports 380–480 V three-phase AC input with up to 97% power supply efficiency, reducing energy loss and boosting performance.

| Liquid Operating Parameters | |
| Liquid Pressure, bar | ≤3.5 |
| Liquid Medium | Pure water (or distilled water) + special corrosion inhibitor or antifreeze (select the ratio according to the freezing Point) |
| Liquid Flow, L/min | Pure Water ≥ 10.2L/min for pure water; if the antifreeze needs to be changed, the flow rate needs to be increased, such as 30% ethylene glycol aqueous solution antifreeze requiring ≥11L/min. <br>*Remarks:10.2L/min corresponds to the temperature difference between inlet and outlet water close to 10.5°C at normal mode. |
