Bitdeer Sealminer A2 228TH

The Sealminer A2 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 unitdelivers 228TH/s in its default “Normal” profile (and up to ≈ 240 TH/s in High-Performance mode) while holding energy consumption to 16.5 J/TH at 25 °C.

Where previous-generation rigs struggle outside tightly-controlled server rooms, the A2 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.
