Key Features & Performance Highlights
-
Industry-Leading 16.0 J/TH Efficiency: The S21 Immersion achieves a groundbreaking energy footprint of just $16 \text{ Joules per Terahash}$. Thanks to the stable thermal dynamics of liquid cooling, the chips do not suffer from the heat-induced resistance typical of air-cooled miners, preserving your profit margins through any market cycle.
-
100% Fanless & Whisper-Quiet Operation: Because this miner is fully submerged in a dielectric fluid tank, it requires zero roaring chassis fans. This completely removes fan noise issues and makes it ideal for operations with strict noise ordinances or commercial multi-use spaces.
-
Zero Dust & Environmental Degradation: Air-cooled miners constantly inhale airborne dust, humidity, and micro-particles that cause board corrosion and premature failure. The immersion-sealed design isolates the hashing chips completely from external air contaminants, extending the hardware lifespan by up to 2-3x.
-
Ultimate Density & Heat Recycling: Liquid cooling allows you to stack hardware closer together without fear of cascading thermal issues. Additionally, the heated dielectric fluid can be routed straight to external heat exchangers to reclaim energy for commercial heating, greenhouse climate control, or industrial hot water networks.
