The Antminer S21 Imm is Bitmain’s premier solution for miners who demand the highest possible ROI through advanced cooling technology. Designed for the SHA-256 algorithm, it is fully optimized for Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV).2 Unlike air-cooled units, the S21 Immersion is built to be submerged in dielectric fluid, significantly extending the life of its 5nm chips while maintaining stable performance in any climate.

Revolutionary Energy Efficiency (16.0 J/TH)

In the competitive landscape of Bitcoin mining, efficiency is everything. The Antminer S21 Imm 215 TH/s operates at a typical power consumption of 3440W, achieving an industry-leading efficiency of 16.0 J/TH. This allows professional miners to maximize their margins even during market volatility and network difficulty increases.

Immersion Cooling Advantages

The S21 Immersion model is the gold standard for large-scale mining farms:

  • Ultra-Silent Operation: With zero internal fans, the unit is nearly silent, making it ideal for deployments where noise regulations are strict.

  • Enhanced Longevity: Immersion cooling prevents dust buildup and oxidation, reducing maintenance costs and downtime.

  • Stable Overclocking: The superior heat transfer of oil allows for more stable operation even in High Energy Mode (HEM), reaching up to 301 TH/s in specific configurations.
