The web interface of the Antminer S21 series impresses with a new modern design, a good overview of the current hash rate, the network connection and the status of the fans. Login to the interface is possible via any normal web browser. The default user name and password are "root", i.e. you can log in with the user "root" and the password "root". If you ever need technical support, our support team will of course be happy to help you after your purchase.

The new Bitmain Antminer S21 series offers a high hash rate of up to 335 TH/s for efficient mining. The Hydro variant enables optimal temperature control through water cooling, while the Classic variants with 188, 195 and 200 TH/s are available in air-cooled versions to meet individual needs. The optimized energy efficiency ensures higher profitability and the advanced technology improves mining performance. The reliable hardware is designed for long-term use and the robust design enables 24/7 operation. Support for the SHA-256 mining algorithm for Bitcoin makes the devices versatile. The simple setup and installation, compatibility with common mining pools and remote monitoring and control options make them particularly user-friendly. The low energy consumption compared to other mining devices ensures cost savings and the guaranteed longevity and stability make them a worthwhile investment.

Cooling solutions for mining farms

We offer various cooling solutions for mining farms and other large-scale projects. Individual containers or stackable containers in various sizes are possible. We also offer the option of choosing between dry and liquid cooling towers. A conventional water-based cooling liquid or a special oil can be used. Our solutions are also scalable for the future. Our trained staff will be happy to advise you on choosing the right solution.

Cooling solutions for large-scale projects

We also offer cooling solutions for medium-sized mining projects. Various containers and smaller containers are also possible here. The cooling itself takes place via dry or liquid coolers. With dry coolers, the cooling liquid is fed through the cooling fins and reduced by fans. With cooling towers, significantly more liquid is used, which leads to greater heat absorption but a higher weight - cooling is also carried out here with fans.

Bitmain Antminer S21 Hydro (335TH/s)

Using an Antminer S21 to mine Bitcoin, Bitcoin Cash or Bitcoin SV offers a high return on investment. Setup and maintenance are simple and the efficient cooling ensures cost-efficient continuous operation. The Antminer S21 offers stable and reliable hardware that can be easily scaled in racks or containers. Integration into an existing mining infrastructure is just as easy as setting up a completely new farm.

The Antminer Hydro models offer a wide range of heat dissipation options thanks to water cooling. With an advanced cooling concept, it is also possible to dissipate waste heat over a longer distance. In particular, this makes it possible to realize setups in which the actual S21 miners are housed inside a building but the actual radiators are located in the (covered) outdoor area. This ensures even better heat dissipation.

We will be happy to advise you on suitable cooling concepts for large-scale projects!
