• Higher Power Envelope: Operating capacity is increased to a standard 1,200 kW (up to 1,300 kW), compared to the ~1,050 kW limit of older generations, providing full power headroom for high-consumption S21 and S23 Hydro units.
• Dedicated Dual Dry Tower Pairing: Standardized to deploy with two container-type dry cooling towers (1,300 kW total heat rejection) in a closed loop, eliminating the scaling and water-treatment headaches of earlier open-tower configurations.
• Upgraded Electrical & Piping: Upgraded DN100 (ISO 2852) quick manifolds delivering >85 m3/h>85 m3/h flow rate, a heavy-duty 1,200A main distribution switch, and improved automated PTC preheating controls.

Which Antminer models are compatible with the ANTSPACE HK3 V7?

The system accommodates up to 210 Antminer hydro miners in a high-density vertical layout. It delivers native, out-of-the-box compatibility with the Antminer S19, S21, and S23 Hydro series (including S19 Hyd./XP Hyd., S21 Hyd./XP Hyd., and the next-generation S23 Hyd. / U3S23H models). All 210 slots are pre-configured with standardized 3U mounting rails, quick-connect fluid couplings, and heavy-duty power harnesses precisely engineered to handle the physical dimensions and intense thermal dissipation of these generations.

How is the dry cooling system configured, and does it require water replenishment?

Each ANTSPACE HK3 V7 unit is paired with

two container-type dry cooling towers

(Dry Tower Container Type × 2), delivering a combined heat dissipation capacity of

1,300 kW

to effortlessly cool the 1,200 kW operational load. Operating as a 100% sealed, closed-circuit loop, the system has

virtually zero water evaporation loss

. Unlike open cooling towers, it requires no daily water replenishment, produces no mineral scaling, and operates cleanly in water-restricted or desert regions.

What electrical capacity and transformer sizing are required?

The HK3 V7 operates on a 400V (±5%) 3-phase industrial power supply at 50/60Hz, protected by an integrated 1,200A main switch (rated operating current: 986A). According to Bitmain’s official infrastructure guidelines, a single 2,500 kVA transformer can cleanly power two (2) ANTSPACE HK3 containers, optimizing substation capital expenditure and electrical efficiency on utility-scale mining pads.

How does the system operate in freezing winter conditions down to -35°C?

The container is officially rated for extreme climates from -35°C to 45°C. It features an intelligent PTC auxiliary electric heating system. During cold-starts when coolant temperature drops below 20°C, the system automatically runs an internal circulation mode with the PTC heaters active, warming the fluid above 20°C before the miners power on. Combined with an approved industrial glycol mixture, this protects ASIC hashboards from thermal shock and freezing damage.

What are the shipping dimensions and civil pad layout for one complete set?

One complete set consists of three standard 20ft High Cube containers (1 mining container + 2 dry cooling towers), each measuring 6,058 × 2,438 × 2,896 mm and certified by the China Classification Society (CCS) for secure international transport. On-site installation simply requires pouring three level concrete pads, positioning the units, and connecting the supplied DN100 chuck couplings (ISO 2852) and power drops—enabling full commissioning within days.

What is the operating noise level, and does it meet local industrial permitting standards?

Unlike conventional air-cooled containers that generate piercing high-frequency noise exceeding 85–95 dBA, the hydro-cooled HK3 V7 container operates extremely quietly (under 60 dBA inside the closed container). The external noise comes solely from the low-RPM, high-efficiency axial fans on the dual dry towers, maintaining sound levels at

≤75 dBA

≤

75

dBA

at 10 meters. This makes local zoning approvals, EPA/environmental permits, and urban-adjacent deployments significantly easier.

How does the routine maintenance of a dry tower compare to open evaporative cooling towers?

Maintenance is drastically reduced. Because the HK3 V7 utilizes a fully sealed, closed-circuit dry cooling loop, it eliminates the need for daily water replenishment, chemical biocide dosing, water softening treatments, and blowdown drainage typical of open evaporative towers. Routine upkeep is limited to periodically inspecting coolant conductivity and using an air/water pressure washer to rinse dust and debris from the dry tower fin coils every 3 to 6 months.
