The Sealminer A2 Pro is Bitdeer’s latest statement piece for SHA-256 mining, striking a pragmatic balance between raw performance and real-world efficiency. Powered by the in-house SEAL02 chip, the air-cooled unit delivers 258TH/s in its default “Normal” profile. while holding energy consumption to 15 J/TH at 25 °C.
Where previous-generation rigs struggle outside tightly-controlled server rooms, the A2 Pro thrives: Bitdeer’s thermal design keeps the unit stable from -20 °C right up to 50 °C, with a custom fan blade and flow field layout that registers 3-4 dB less noise than most industry miners in the same class.
The SEAL02 architecture sustains hashrate even as ambient conditions swing, making it an ideal choice for warehouse deployments, container farms, or edge locations with tougher climates.
