About the SEALMINER A4 Ultra Hydro

The SEALMINER A4 Ultra Hydro is Bitdeer's efficiency flagship and the first SEALMINER below 10 J/TH. It runs at 886 TH/s on 8,373 W, which is 9.45 J/TH. In our catalog it is among the most efficient hydro SHA-256 machines and among those with the most hashrate per unit. It is built for hydro sites where rack density and joules per terahash decide the economics.

It needs three phase power at 380 to 480 V and draws about 201 kWh a day per unit. The flat chassis, 482 × 665 × 86 mm and 20.5 kg, is made for dense racks. The site provides the liquid cooling loop with manifold plumbing, a dry cooler or water source, plus power cords and a PDU. At about 50 dB the unit itself is quiet; the operating range is 5 to 45 °C.

Questions

What buyers ask about the SEALMINER A4 Ultra Hydro

All questions

How much power does the SEALMINER A4 Ultra Hydro use?

8,373 W at 886 TH/s, about 201 kWh a day.

How efficient is the SEALMINER A4 Ultra Hydro?

9.45 J/TH: every terahash per second costs 9.45 watts. That puts it among the most efficient hydro cooled SHA-256 miners in our catalog.

Which coins can the SEALMINER A4 Ultra Hydro mine?

Bitcoin (BTC) and other coins on the SHA-256 algorithm, through a mining pool of your choice.

What does a site need for the SEALMINER A4 Ultra Hydro?

Supply at 380 to 480 V, three phase, a liquid cooling loop, a dry cooler or water source, manifold plumbing, and power cords with a PDU. The operating range is 5 to 45 °C.

How loud is the SEALMINER A4 Ultra Hydro?

About 50 dB at the unit, because the heat leaves through the water loop rather than through fans. At the site you mostly hear the heat rejection outside, a dry cooler for example; our guide to site noise explains the options.

What warranty comes with the SEALMINER A4 Ultra Hydro?

New units carry the manufacturer warranty. Keep the stock firmware while it runs: third party or modified firmware generally voids it.

Can I order a single unit?

Yes. New models ship from a single unit, DAP or DDP to your door; the sea freight terms apply from 100 units.

How fast can you deliver?

Air freight takes 5 to 10 days door to door, sea freight 4 to 8 weeks. The lead time for your quantity is on the quote, which you get within 24 hours on business days.
