About the SEALMINER A2 Pro Air
The SEALMINER A2 Pro Air is the air cooled counterpart of the A2 Pro Hydro, from Bitdeer's previous generation, widely deployed and well understood in the field. In this factory version it runs at 255 TH/s on 3,790 W, which is 14.9 J/TH; the 260 TH/s version draws 3,874 W at the same efficiency, which is also that of the A2 Pro Hydro. Against the A2 it delivers more hashrate at better efficiency, and the A3 and A4 air models in the same chassis are more efficient still.
It runs on single phase supply at 220 to 277 V and uses about 91 kWh a day per unit; the units sit on conventional shelves, with no liquid infrastructure. The site provides airflow and heat exhaust, hot and cold separation, and sound insulation near housing, since 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, the chassis of every SEALMINER air model in our catalog.

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: 3,790 W rated power, 24 hours, one unit. Cooling overhead and PSU losses not included; no revenue assumptions.

Read before you buy the SEALMINER A2 Pro Air
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.
Air, hydro or immersion: matching cooling to your site
The cooling route you pick decides which machines you can even consider, how loud your site is, and how much you spend before the first miner is switched on.
How loud is a mining site, and what to do about it
Noise is the most common reason a running site gets shut down, and the least often budgeted for. What the numbers mean, and what actually works.
