Bitmain Antminer S21 Hyd (335Th)SHA-256 BTC (Bitcoin)ASIC miner
The Bitmain Antminer S21 Hyd (335Th) is a hydro-cooled ASIC miner built for SHA-256 Bitcoin mining, delivering a hash rate of 335 TH/s with a power efficiency designed to reduce electricity costs. This model integrates Bitmain’s latest hydro-cooling system, which lowers operating temperatures and extends hardware longevity compared to air-cooled units. The miner’s firmware supports overclocking and underclocking, allowing operators to balance performance against power draw based on local energy pricing.
Constructed with industrial-grade aluminium and corrosion-resistant components, the S21 Hyd meets the durability demands of large-scale mining farms. It operates within a typical ambient temperature range of 5 to 35°C, with the hydro system maintaining internal temperatures below 60°C under full load. Standard connectivity includes Ethernet for network access and a dedicated power supply unit rated for 3000W, typical for high-end ASIC miners in this class.
This miner suits professional mining operations, from mid-sized farms to enterprise-scale deployments, where energy efficiency and thermal management are critical. Buyers typically source these units for bulk deployment, with common trade terms including FOB Shenzhen or CIF to major ports. The unit’s modular design allows for rapid replacement of hash boards, minimising downtime in high-availability environments.

Sourcing Bitmain Antminer S21 Hyd (335Th) SHA-256 BTC ASIC miner from Guangdong Technologies Ltd - China Import Guide
Before placing an order, verify the supplier’s ability to provide the exact Antminer S21 Hyd (335Th) model with hydro-cooling, as some listings may advertise air-cooled variants under similar names. Request confirmation of the hash rate, power consumption, and cooling method in writing, along with any available certifications for the hardware. Ensure the supplier can provide proof of authenticity, as counterfeit mining equipment is a known issue in this market.
Confirm logistics details such as lead time, which can vary significantly based on demand and production schedules. Typical lead times for ASIC miners range from 4 to 12 weeks, depending on the supplier’s inventory. Discuss Incoterms like FOB Shenzhen or CIF to your nearest port, and clarify whether the quoted price includes hydro-cooling accessories or if these are billed separately. Payment terms should also be agreed upon, with common options including TT (Telegraphic Transfer) or LC (Letter of Credit).
Quality checks should include a pre-shipment inspection to verify the miner’s hash rate, power draw, and cooling system functionality. Request test reports or videos of the unit in operation to confirm it meets the specified performance metrics. Documentation should include a detailed invoice, packing list, and any relevant certifications. For added security, consider arranging a third-party inspection before shipment to ensure the equipment matches the agreed specifications.
