Bitmain Antspace HK3 Liquid Cooling Container


Built with efficiency and hotter climates in mind, the BITMAIN ANTSPACE HK3 (known as model designation Antbox H3 V2 internally) has a maximum capacity of 210 units of Antminer S19 Pro+ Hydro with total consumption of a little over 1MW. The minimum ASIC quantity to compliment the order will be 195 S19 Hydro units per container. The AntSpace HK3 is sold as a two-piece stackable set– a cooling tower and mining container. Refer to the brochure in the downloads tab for technical details. Unlike Bitmain, we provide DDP (delivery duty paid) service for the ASIC miners, but not the container. THE UNIT IS NOW FREE WHEN PURCHASING MOQ OF 195 S19 HYDRO 250T MODEL ONLY.


Price for AntSpace does not include door-to-door ocean freight service. Freight costs will be quoted at time of loading as shipping costs vary weekly, and by location. ExWorks / FOB incoterms available. 1 year manufacturer warranty included. S19 Pro+ Hydro warranty void if used outside the AntSpace HK3 system. Coolant not included.

  • Environmental Requirements

    Environmental Requirements
    1 Cooling tower is required to be placed on flat ground, horizontal degree (±1 degree).
    2 The ground surfaced is required to be hardened and stable, able to withstand at least 14-ton load.
    3 A 10-ton crane is needed for unloading ANTSPACE  and cooling tower.
    4 Add-on items such as stairs, transformers, cables, bridge racks and cable distribution boxes are not included in the delivery of ANTSPACE. Bitmain team can provide design suggestions if needed.
    5 Client needs to confirm the opening direction of container and it needs to face air-intake. Door on left is current design by default.
    6 Keep at least 2 meters of air in-take space around the cooling tower.
    7 Altitude: ≤3000m. If the altitude is higher than 1000-meter, transformer and switch should be derated, the total power of ANTSPACE must be decreased by 1% for each elevation increment of 100 meters.
    8 Operating temperature: -25°C to 40°C. Operating humidity: 10%RH to 90%RH. When the initial coolant temperature is below 20 °C, the internal circulation should be turned on to heat up the coolant to above 20 °C before starting the mining machine.
    9 When the ambient temperature is below 5 ℃, the cooling tower can be switched to cold-dry mode.
    10 Select distilled water or suitable antifreeze solution as coolant based on local climate conditions and extremes.
    11 The suitable ambient temperature for ANTSPACE does not represent the suitable ambient temperature for the mining machines thesmelves.
