The Bitmain Antminer S21 Hydro (319 TH) — the strongest Bitcoin miner of all time

The Antminer S21 Hydro is the latest water-cooled Bitcoin miner from Bitmain. This incredible miner is the strongest Bitcoin miner of all time and combines the latest technology with an innovative water-cooled solution, making it particularly suitable for mining. With an impressive hashing power of 319 terahashes per second (TH/s) at just 5,360 watts, the Antminer S21 Hydro is a real powerhouse with maximum efficiency.

An outstanding feature of this miner is its water-cooled architecture, which optimizes heat dissipation and cooling. This not only results in a long hardware life, but also reduces energy consumption, significantly reducing your operating costs. The Antminer S21 Hydro is therefore not only powerful, but also more environmentally friendly than other devices.

In addition, this Bitmain miner has a user-friendly interface that allows you to conveniently monitor and control your mining activities. The clear user interface provides real-time information on hashrate, temperature and energy consumption so you always have an overview.

Overall, the Bitmain Antminer S21 Hydro offers an unbeatable combination of performance, efficiency, and ease of use. A device that we can really highly recommend.

In addition to the S21 Hydro, you can also obtain the appropriate cooling unit from us. For example, you can find an external cooling unit for a single device here or a server rack for up to 4 hydro miners here. We also offer hydro containers in various sizes for larger projects, including the Bitmain Antspace HK3 V6 for up to 210 hydro miners.
