The Sealminer A3 Pro Hydro represents the pinnacle of vertical integration in the mining industry. By pairing Bitdeer’s second-generation SEAL03 chips with a high-performance 2U rack-mounted liquid cooling system, this miner provides a level of power density and efficiency that was previously impossible for air-cooled hardware.
SEAL03 Chip: A Breakthrough in Energy Efficiency
The A3 Pro Hydro utilizes high-bin SEAL03 4nm chips, optimized for high-voltage performance. While achieving a massive 660T output, it maintains a surgical 12.5 J/TH efficiency. This allows large-scale operations to maximize their Bitcoin yield per square foot while significantly lowering the cost per terahash ($/TH).
Engineered for High-Density Hydro Facilities
The A3 Pro Hydro is designed for the modern industrial farm:
-
Silent Hashing: Operating at approximately ~50 dB, the water-cooled loop eliminates the deafening noise of high-RPM fans, allowing for more flexible site locations.
-
Thermal Precision: Liquid cooling prevents the “hot spots” common in air-cooled miners, ensuring that the 660T hashrate remains stable even during 24/7 peak operation.
-
Space Optimization: The 2U server form factor allows for standard 19-inch rack mounting, making it easier to manage hundreds of units within a single container or data center.
