MM-Hydro-Vault 210 (Hydro ASIC Mining Container)

The MM-Hydro-Vault 210 represents MillionMiner's entry into hydro containerized mining, built for operators who need the thermal efficiency and noise reduction of liquid cooling at 1MW facility scale. It competes directly with the Bitmain Antspace HK3 (DWT-C) at the same 210-miner capacity and 1MW power class.The core architecture is closed-loop liquid cooling. Coolant circulates from the CDU (Coolant Distribution Unit) through hydraulic pipelines to each of the 210 hydro miner positions, absorbs heat from the ASIC chips, returns to the CDU for temperature regulation, and passes through an industrial dry cooler for external heat rejection to ambient air. The closed loop means coolant recirculates continuously without consumption (except periodic makeup for evaporation loss), making this dramatically more water efficient than open-loop or evaporative cooling tower systems.Three practical advantages over MillionMiner's air cooled containers. First, operating temperatures: liquid cooling maintains chip temperatures 15 to 25 degrees lower than air cooling at equivalent ambient conditions, reducing thermal stress and extending hardware lifespan. Second, noise: hydro miners operate at 40 to 50 dB versus 75 to 85 dB for air cooled units, making the Hydro-Vault deployable in noise-sensitive locations where air cooled containers would face complaints or zoning restrictions. Third, density: removing internal fans and exhaust systems from the cooling equation allows tighter miner packing, fitting 210 hydro units in roughly the same footprint where air cooled containers hold 189 to 216.The container ships fully pre-engineered. All hydraulic pipelines connecting CDU to miner positions, all electrical cabling for the industrial grade power distribution system, and the complete cooling circuit including dry cooler integration are pre-installed. On site, the operator connects external three phase power at 380 to 415V AC 50/60Hz and a water supply for initial fill and periodic makeup of the closed-loop system. No on-site plumbing engineering, no custom pipeline fabrication, no CDU assembly.Compatible with Antminer S19 Hydro and S21 Hydro series per the listing. At 1MW with 210 S19 Hydro units at 5,000W each: approximately 1,050KW total, closely matching the 1MW capacity. S21 Hydro at 5,265W per unit: 1,106KW for 210 units, slightly above 1MW, so 190 units would be the safe deployment at full power. S23 Hydro at 5,510W: approximately 181 units within 1MW. Confirm S21 XP Hydro, S23 Hydro, and Whatsminer hydro series compatibility and adjusted unit counts with MillionMiner.The Hydro-Vault 210 versus the Bitmain Antspace HK3 comes down to brand ecosystem and support model. The HK3 is Bitmain's purpose-built solution with the DWT-C cooling tower and institutional safety certifications (NFPA 79, UL 508A, CSA C22.2). The Hydro-Vault 210 is MillionMiner's solution with a dry cooler based heat rejection system and direct MillionMiner support. Buyers should compare pricing, lead times, certifications (confirm Hydro-Vault certification status), and multi-brand miner compatibility during the ordering consultation.Reinforced ISO container structure for weather-resistant industrial deployment. Currently out of stock at MillionMiner. Made to order with lead time dependent on project scope.
