Product Details

Bitdeer SealMiner A2 226TH Standard Air Cooled SHA-256 Bitcoin Miner

The Bitdeer SealMiner A2 is the air cooled standard bin on SEAL01 silicon. 226 TH/s at 3,729W. Previous generation to the A3 Air (260 TH/s, 14.0 J/TH) and A3 Pro Air (290 TH/s, 12.5 J/TH) on SEAL02. One specification difference between A2 and A3 matters beyond efficiency: operating temperature. The A3 series operates from minus 20 to 45 degrees Celsius, enabling sub zero container deployments without intake heating. The A2 operates from 5 to 40 degrees. For cold climate mining in Canada, Russia, Nordic countries, or high altitude locations, the A3's cold tolerance is a practical infrastructure advantage the A2 cannot match. For temperature controlled facilities (warehouses, data centers, converted buildings), the narrower range is irrelevant. If your mining environment stays between 5 and 40 degrees year round, the only comparison point is price versus efficiency. 226 TH/s at 16.5 J/TH versus the A3 Pro Air at 290 TH/s and 12.5 J/TH. The A3 Pro is 28 percent faster and 24 percent more efficient. The A2's value is entirely in its discount. How much cheaper per unit, and how cheap is your electricity? Those two numbers determine whether the A2 or A3 produces more Bitcoin per dollar invested. 220 to 277V at 75 dB. 15.5 kg at 197 x 365 x 292mm. Ethernet connectivity. The A2 Pro Air (255 TH/s, 3,790W) is the top bin SEAL01 option. Bitdeer (NASDAQ: BTDR) designs chips and operates farms. Bitcoin, Bitcoin Cash, all SHA 256.

SealMiner A2 226TH Standard Air Cooled Bitcoin Miner

Bitdeer A2 standard bin. 226 TH/s at 3,729W and 16.5 J/TH on SEAL01. Previous gen below the A3 series. Critical difference: no minus 20 degree cold floor (5 to 40 degrees versus the A3's minus 20 to 45). Temperature controlled facilities: only price matters. Cold climate containers: the A3's cold tolerance is a real infrastructure advantage. The A2 requires intake heating in sub zero environments. A3 Pro Air (290 TH/s, 12.5 J/TH) is 28 percent faster and 24 percent more efficient. A2 competes on discount pricing. 220 to 277V at 75 dB. 15.5 kg. A2 Pro Air (255 TH/s) also available as top bin. Bitdeer NASDAQ BTDR. Ethernet. For fleet planning, model the A2 against the A3 at your specific electricity rate. Create a spreadsheet comparing: acquisition cost per unit times fleet size versus total daily electricity cost times deployment days. The lower total cost of ownership wins. At cheap electricity, A2 fleet volume typically wins. At expensive electricity, A3 efficiency typically wins. Bitdeer NASDAQ BTDR. Established company with real infrastructure. A2 generation firmware is mature and well tested.
