Bitdeer SealMiner A2 Pro Air 255TH Top Air Cooled SHA-256 Bitcoin Miner at 14.9 J/TH

The Bitdeer SealMiner A2 Pro Air produces 255 TH/s at 3,790W with air cooling, matching the 14.9 J/TH efficiency of its hydro cooled siblings in the A2 family. For facilities that cannot or choose not to install water cooling infrastructure, this is Bitdeer's strongest air cooled option in the second generation SealMiner lineup. The A2 Pro Air runs on the same SEAL01 custom silicon as the hydro variants. Identical chip, identical efficiency, different cooling method. The trade off is straightforward: you avoid the capital cost of hydro infrastructure (cooling loops, pumps, manifolds, fluid) in exchange for higher noise at 75 dB and lower hashrate per unit compared to the 500 TH/s hydro model. At 197 x 365 x 292mm and 15.5 kg, it is a standard standalone ASIC form factor. Voltage range of 220 to 277V covers most single phase industrial and commercial circuits worldwide. Not designed for 110V residential outlets. Operating conditions run from 5 to 40 degrees Celsius at 10 to 90 percent humidity. Adequate ventilation and exhaust are essential at this power and noise level. Ethernet connectivity for pool setup. For fleet operators evaluating the A2 series, the Pro Air and Pro Hydro models share the same efficiency, so the decision comes down to facility infrastructure and total cost of ownership modeling. The A2 Pro Air is the previous generation to the A3 Pro Air (290 TH/s at 12.5 J/TH on SEAL02). The A3 delivers 14 percent more hashrate at significantly better efficiency. Like the hydro models, the generational trade off comes down to acquisition cost versus electricity cost. Operators with cheap power may find the A2 Pro Air's lower purchase price compensates for the higher per terahash power draw over the hardware's useful life.

SealMiner A2 Pro Air 255TH Air Cooled Bitcoin Miner

255 TH/s at 14.9 J/TH on SEAL01 custom silicon with air cooling. Identical efficiency to the A2 Pro Hydro without requiring water cooling infrastructure. 3,790W on 220 to 277V single phase.

The key advantage is infrastructure simplicity. No cooling loops, no pumps, no manifolds, no fluid management. The trade off is 75 dB noise (versus 50 dB hydro) and lower per unit hashrate (255 versus 500 TH/s). For facilities without hydro capability, the A2 Pro Air delivers the same J/TH efficiency without the capital expenditure on liquid cooling systems. 15.5 kg standalone format at 197 x 365 x 292mm with Ethernet.

Previous generation to the A3 Pro Air (290 TH/s at 12.5 J/TH on SEAL02). The A3 is more efficient, but the A2 offers lower acquisition cost. For fleet buyers, the decision depends on your electricity rate and deployment timeline. At cheap power, older generation hardware with lower upfront cost can still return well. At expensive power, efficiency wins and the A3 is the better long term choice.

SealMiner A2 Pro Air 255TH BTC Miner

255 TH/s SHA 256 at 3,790W and 14.9 J/TH. Bitdeer's top air cooled A2 SealMiner on SEAL01 chip. Same efficiency as the hydro variants without liquid cooling infrastructure. 220 to 277V at 75 dB. Standalone 15.5 kg chassis for facilities that prioritize simplicity over rack density. Previous generation to the A3 Pro Air (290 TH/s, 12.5 J/TH on SEAL02). Lower upfront cost with higher per terahash electricity expense.
