The A4 series isn't just an update; it's a generational leap. Led by the A4 Ultra Hydro, we've pushed power efficiency down to 9.45 J/TH*, shattering the 10-point ceiling. The A4 Pro series also maintains a stable 10.9 J/TH*. It's not just a lower number—it's a higher wall of protection for your long-term profitability.
From up to 900 TH/s* on the A4 Ultra Hydro, to 730 TH/s* at the upper end of the A4 Pro Hydro range, and 360 TH/s* for the A4 Pro Air, the A4 series defines a clear hashrate tier. Optimized thermal balance enables stronger computational performance, while built-in hashrate headroom supports consistent operation as mining difficulty rises.
The SEALMINER A4 series redefines environmental adaptability. Leveraging advanced hydro cooling, the A4 Ultra Hydro and A4 Pro Hydro ensure stable operations across a broad spectrum of 20°C to 55°C, effectively mitigating chip thermal fatigue.
Meanwhile, the A4 Pro Air features a refined thermal architecture capable of thriving in extreme conditions from -20°C to 50°C. Regardless of the environment, core components remain in their "optimal comfort zone" for peak efficiency.
Compact dimensions (W*D*H)
The SEALMINER A4 Hydro series features a standard 2U form factor (482 × 665 × 86 mm), designed to integrate seamlessly into professional server racks. Meanwhile, the A4 Pro Air maintains the signature compact footprint of our air-cooled lineup, enabling high-density deployment and allowing operators to achieve higher hashrate per square foot while significantly reducing the total cost of ownership (TCO) per terahash.
Meanwhile, the A4 Pro Air operates with low noise, while the A4 Ultra Hydro and A4 Pro Hydro run at near-silent levels—further enhancing the overall operational experience in high-density deployment environments.
The A4 series continues the legacy of up to 97% power supply efficiency from the previous generation. In particular, the hydro-cooled models, powered by 380–480V three-phase AC input, are designed to minimize transmission loss and internal energy waste. We focus on improving the conversion of input power into computational output, reducing unnecessary energy loss.
