Industry-Leading Efficiency (17.5 J/TH)

Efficiency is the key to mining profitability. The S21 Imm operates at an optimized 17.5 J/TH, making it one of the most cost-effective miners globally. This low energy consumption per Terahash allows you to maintain high margins even when network difficulty rises or energy prices fluctuate. Lower hashrate S21 Immersion options

The Power of Immersion Cooling

By removing high-speed fans and submerging the hardware in specialized dielectric oil, the Antminer S21 Imm 300T offers several critical advantages:

  • Silent Mining: Zero fans mean the unit operates in near-total silence, perfect for noise-restricted zones.

  • Extended Life Cycle: Immersion protects sensitive chips from dust, humidity, and oxidation, drastically reducing maintenance costs.

  • Superior Heat Management: Liquid cooling is significantly more efficient than air, preventing thermal throttling and ensuring 24/7 stability.
