SEALMINER A4 Pro Air
Bitcoin miner from Bitdeer. Efficiency of the current generation in a standard air cooled chassis. Brings A4 joules per terahash to sites that cannot build a water loop.
About the SEALMINER A4 Pro Air
The SEALMINER A4 Pro Air brings the efficiency of Bitdeer's A4 generation to a standard air cooled chassis. It runs at 336 TH/s on 3,662 W, which is 10.9 J/TH: the most efficient air cooled SHA-256 miner in our catalog, and the one with the most hashrate per unit. It is made for sites that cannot build a water loop.
It runs on 220 to 277 V and uses about 87.9 kWh a day per unit. Like every air cooled miner it needs airflow and heat exhaust, hot and cold separation, and sound insulation near housing; it runs at about 75 dB. The rated range is 5 to 45 °C ambient. Each unit measures 197 × 365 × 292 mm and weighs 15.5 kg.

Air cooling. The simplest of the three routes and the lowest infrastructure cost. Sustained ambient above the rated range derates performance, so size the exhaust for the warmest week.
Energy only: 3,662 W rated power, 24 hours, one unit. Cooling overhead and PSU losses not included; no revenue assumptions.

What to buy at your power price: a shortlist by cents per kWh
The same catalogue produces four completely different shortlists depending on one input. Find your band and the hardware question mostly answers itself.
The best ASIC miner for a small site, one to twenty machines
Small deployments have constraints large ones do not: a fixed electrical supply, neighbours within earshot and nobody on site to fix things. The right machine follows from those, not from the efficiency table.
The breakeven power price, and why we ask for yours first
Every machine has an electricity price above which it stops making money. Work that number out and most of the hardware decision answers itself.
