SEALMINER A4 Pro Hydro
Bitcoin miner from Bitdeer. The volume unit of the A4 hydro range. Same 2U chassis as the Ultra at a lower price per terahash, for operators scaling an existing loop.
About the SEALMINER A4 Pro Hydro
The SEALMINER A4 Pro Hydro is the volume unit of Bitdeer's A4 hydro range, in the same chassis as the A4 Ultra Hydro. It runs at 680 TH/s on 7,412 W, which is 10.9 J/TH: the efficiency of the A4 Pro Air at about twice its hashrate. It is among the most efficient hydro SHA-256 machines in our catalog and among those with the most hashrate per machine.
It needs three phase power at 380 to 480 V and draws about 177.9 kWh a day per unit. The site provides the liquid cooling loop with manifold plumbing, a dry cooler or water source, plus power cords and a PDU. The unit runs at about 50 dB, far quieter than air cooled machines, and the operating range is 5 to 45 °C. Each unit measures 482 × 665 × 86 mm and weighs 20.5 kg, the same as every SEALMINER SHA-256 hydro model in our catalog.

SEALMINER against Antminer: the flagship machines compared
Bitdeer's top hydro machine and Bitmain's sit within half a joule of each other, and the choice between them turns on things the spec sheet does not print.
Hydro miners compared, and what the loop really costs
Water cooled machines hold the efficiency frontier and they are quiet enough to put near people. They also come with a construction project attached, and that is the part to price before the hardware.
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.
