Import Bitmain Antminer S21 Xp Hyd (473th) Sha-256 Btc (Bitcoin)Asic Miner — Buy in wholesale FOB from Supplier in China

The Bitmain Antminer S21 XP Hyd (473Th) is a liquid-cooled ASIC miner engineered specifically for SHA-256 algorithm mining, delivering a hash rate of 473 Th/s. This unit employs hydro-cooling technology, replacing traditional air-cooled fans with a water circulation system that dissipates heat more efficiently than convection-based designs. The machine requires connection to an external cooling tower or water chiller infrastructure, which the buyer must source separately or confirm with the supplier. Power efficiency and thermal management are the defining engineering priorities of this generation, with the XP Hyd variant positioned at the premium end of Bitmain's S21 product line.

The hash rate of 473 Th/s represents the current flagship specification for this model series, achieved through a 5nm or smaller process node chip architecture typical for this generation of Bitmain equipment. The hydro-cooling system operates with a coolant mixture of water and glycol, with flow rates and inlet temperatures that must be maintained within specified ranges to prevent thermal throttling or hardware damage. The unit ships in an enclosed chassis designed for rack mounting in data centre environments, with fluid connections requiring standard plumbing fittings. The build quality centres on sustained operation at maximum computational load, with mean time between failures dependent on coolant quality, flow consistency, and ambient conditions.

This miner targets industrial-scale Bitcoin mining operations, hosting facilities, and large private farms with existing liquid cooling infrastructure or capital allocated to build it. Individual miners entering the sector should calculate total cost of ownership carefully, incorporating the cooling system capital expenditure alongside the unit purchase. Buyers should confirm with Guangdong Technologies Ltd the exact power supply requirements, including voltage and amperage per rail, as these determine compatibility with local electrical infrastructure. Warranty terms, repair depot locations, and firmware update policies should be verified directly with the supplier before order placement.
