Cooling solutions for large-scale projects and mining farms

Large Mining Farm Cooling

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.



Professional cooling mining farm

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.



S21 Hydro

The Bitmain Antminer S21 Hydro impresses with its new innovative water cooling.

  • up to 335 TH/s
  • can be used with radiator (4.5 / 8 /12 KW)
  • Water-cooled
  • can be used in a rack (10/28) or hydro container

Bitmain Antminer S21 188-200 TH/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!

The Bitmain Antminer S21 is available in various air-cooled versions with 188, 195 and 200 TH/s.

  • 188-200 TH/s
