Antminer S21 Hyd Description

The Bitmain Antminer S21 Hyd is a purpose-built hydro-cooling BTC miner designed for industrial-scale operations. Unlike conventional air-cooled machines, the S21 Hyd circulates liquid through a sealed system, keeping thermal levels stable and extending overall hardware lifespan. This allows mining farms to run higher densities with fewer cooling challenges.

Delivering 335TH/s at approximately 5360W, the S21 Hyd reaches an energy efficiency of 16 J/TH, making it a dependable choice for long-term SHA-256 mining. Whether you operate a large hydro-cooled facility or are upgrading from an older S19 or S17 generation, this model offers a significant improvement in performance, thermal consistency, and uptime.

The miner is engineered for 380–415V three-phase electrical systems, which ensures steady power delivery under continuous load. It pairs best with a professionally installed hydro-cooling loop that maintains adequate flow rate, pressure stability, and clean coolant quality.

Best Use-Case	Professional large-scale mining, high-efficiency BTC output, maximum ROI operations Medium-sized farms, water-cooling entry setups, cost-balanced operations
Main Advantages	Highest hashrate and best efficiency; significantly higher BTC production; ideal for industrial sites Lower upfront cost; easier hydro deployment; stable performance with moderate hashrate
Considerations	Higher initial investment; requires strong cooling and power infrastructure Lower hashrate and efficiency; slower ROI in high-electricity regions

Notes

(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.
