The Sealminer A3 Hydro marks a major shift in the SHA-256 landscape. By leveraging Bitdeer’s self-developed 4nm SEAL03 architecture, this miner achieves performance levels that rival the industry’s top-tier water-cooled hardware. Designed for 19-inch rack mounting, it offers a seamless path to scaling for industrial-scale deployments.
Proprietary SEAL03 Chip Technology
The A3 Hydro is built around Bitdeer’s second-generation SEAL03 chips, which are specifically optimized for the post-halving mining environment. With an efficiency of 13.5 J/TH, the A3 Hydro significantly reduces operational costs compared to older 20-30 J/TH units, ensuring long-term profitability even during market volatility.
Industrial Hydro-Cooling & Silent Operation
Unlike air-cooled miners that produce significant noise and heat exhaust, the A3 Hydro utilizes a advanced water-cooling loop:
-
Heat Dissipation: The liquid-cooling system allows for 24/7 operation with nearly zero thermal throttling, extending the lifespan of the ASIC chips.
-
Silent Mining: Operating at approximately 50 dB, the A3 Hydro is virtually silent compared to air-cooled equivalents, making it suitable for noise-sensitive environments.
-
High-Density Deployment: The 2U server-style design is optimized for rack-mounting, allowing miners to pack more hashrate into a smaller footprint.
