Bitmain Antspace HD5 Hydro Mining Container (1.5MW)

The Bitmain Antspace HD5 is purpose-built infrastructure for operators running hydro-cooled Antminers at industrial scale. It is a 40-foot ISO-format container that integrates miner mounting, power distribution, and liquid cooling connections into one certified, factory-tested unit, paired with a dedicated dry cooling tower for heat rejection. The design target is straightforward: take an operator from a power connection and a concrete pad to 308 operational hydro miners with the minimum possible on-site engineering. Capacity and compatible hardware. The HD5 houses up to 308 units of Bitmain's hydro-series Antminers, spanning the S19 Hydro, S21 Hydro, and the newer S23 Hydro. Miners mount on both sides of the container, with 140 to 154 units per side depending on the configured main pump frequency (41 Hz for 140-per-side, 45 Hz for 154-per-side). This flexibility lets operators tune the coolant flow rate, 67.2 m³/h or 73.9 m³/h respectively, to the specific miner model and density they are deploying. Power distribution and electrical specifications. The container's working power is 1,512 kW under normal load and up to 1,765 kW at maximum, with each miner drawing a rated 10A. The power distribution cabinet uses four main switches rated 1200A each, with a rated current of 700A×4. Input is 400V±5% at 50/60Hz, three-phase. The inlet copper cabling specification is substantial: each phase (L1, L2, L3) requires eight runs of 400kcMil (185mm²) single-core cable rated 600V or higher, with four runs each for neutral and protective earth. This is genuine utility-scale electrical infrastructure, and operators should plan transformer and switchgear provisioning accordingly. A single 3,750 kVA transformer supports two HD5 containers operating simultaneously. The EC2-DT dry cooling tower. Heat rejection is handled by a separate container-format dry cooler, the EC2-DT, matching the main container's 12,192 × 2,438 × 2,896 mm footprint. It dissipates the full 1,500 kW thermal load generated by the miners. At 30°C ambient temperature, it maintains outlet water temperature at 35°C±1°C, which is the inlet temperature the hydro miners need for stable operation. The tower consumes 80 kW or less for its own pumps and fans, uses only 2.1 m³ of coolant in the loop, and produces 75 dBA of noise measured at 15 metres. The dry-tower architecture is the defining cooling choice: unlike evaporative wet cooling towers, a dry cooler rejects heat through air-to-liquid heat exchange without consuming water through evaporation. This eliminates water sourcing, treatment, and blowdown management, which is a significant operational advantage in water-constrained or remote sites, at the trade-off of slightly higher ambient-temperature sensitivity than a wet system. Weights and logistics. The main container ships at 11 tonnes and reaches 17.2 tonnes operating weight once filled with miners and coolant. The dry cooling tower ships at 12 tonnes and operates at 13.5 tonnes. Both are standard 40-foot ISO dimensions, so they move on standard container transport, crane onto a prepared pad, and connect via DN100 (ISO 2852 PN16) coolant interfaces between the container and the cooling tower. Certification and compliance. The container structure carries China Classification Society (CCS) certification, the standard for shipping-container structural integrity. The full unit carries CE and UL marks. The electrical and control systems comply with NFPA 79:2021 (industrial machinery electrical standard), UL 508A:2018 R8.21 (industrial control panels), CSA C22.2 No.14-18 (Canadian industrial control equipment), ANSI/ISO 12100:2012 (machinery safety), and IEC 60204 Ed 5.1 2009 (electrical equipment of machines). Power distribution cabinets, PDUs, cables, switches, and network cabling are individually UL/CUL certified. Where the HD5 fits in a deployment. This is large-scale infrastructure. A fully populated HD5 running S21 Hydro miners represents over 100,000 TH/s of Bitcoin hashrate in a single container footprint. Operators choosing the HD5 over building fixed infrastructure gain speed (factory-tested unit versus months of construction), portability (the entire farm can relocate), lower per-unit land and cabling cost, and a single certified system rather than a patchwork of separately-permitted components. The container scales naturally: power one or two units per transformer, deploy multiples across a site, and expand by adding containers rather than rebuilding fixed plant. MillionMiner ships the Antspace HD5 worldwide DDP with duties and customs handled before delivery, and supports installation and commissioning. For operators who prefer not to host on their own site, MillionMiner operates hosting facilities across four US data centers.
