Bitmain Antminer S21 Hyd Bitcoin Miner 335TH/s | BT-MINERS

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.
