Powered by the SEAL02 4nm Architecture
The heart of the A2 Pro Hydro is the SEAL02 chip, a second-generation 4nm processor optimized for the SHA-256 algorithm. This technology allows the miner to maintain a consistent 500 TH/s output while optimizing power draw. The efficiency of 14.9 J/TH ensures that even during periods of increased network difficulty, your operational margins remain robust. Compare the A2 Pro Hydro with the Antminer S21 XP Hydro
The Hydro-Cooling & 2U Advantage
Unlike traditional “tower” style miners, the A2 Pro Hydro is built for the modern mining farm:
-
Silent & Stable: The hydro-cooling system eliminates high-decibel fan noise and protects internal components from dust and oxidation, significantly extending hardware life.
-
Rack-Mountable Design: The 2U server chassis allows for high-density deployment in standard server racks, optimizing floor space and simplifying airflow management.
-
Triple Mode Performance: The unit features flexible operating modes, allowing you to switch between High Performance (up to 610 TH/s), Normal, and Low Power modes to adapt to changing electricity costs.
-
Industrial Thermal Management: Designed to operate with inlet liquid temperatures up to 60°C, providing flexibility in heat reuse and dry-cooler configurations.
