Bitmain Antminer S21 Imm 300 TH/s – Enterprise-Grade 300 Terahash Immersion Power
Achieve ultimate thermodynamic stability and extend your equipment’s operating lifespan to the absolute maximum with the state-of-the-art Bitmain Antminer S21 Imm 300 TH/s. Specifically engineered to operate completely submerged inside dielectric fluids, this flagship SHA-256 server strips away traditional high-RPM cooling fans. It provides enterprise data centers and multi-megawatt installations with an exceptionally quiet, ultra-dense scaling solution that completely eliminates the physical hazards of traditional air-cooled configurations.
By operating inside a controlled liquid immersion tank, the S21 Imm 300 TH/s avoids air-based thermal spikes, ensuring perfectly balanced chip junction limits. This yields extreme 24/7 processing stability to aggressively harvest block rewards across Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV).

Key Features & Performance Highlights
-
Massive 300 TH/s Dense Footprint: Packing a full 300 Terahashes into a standard server layout enables industrial operators to dramatically amplify their data center block yield. By running at peak capacity inside fluid beds, it maximizes computing density per square foot.
-
Elite $16.0 \text{ J/TH}$ Operational Efficiency: Leveraging Bitmain’s state-of-the-art custom semiconductor architecture, the S21 Imm turns its power draw into incredible processing density. Operating directly within a dielectric liquid environment drastically curbs leakage currents, defending your net margins against difficulty variations.
-
Total Environmental Isolation (Dustproof & Fanless): Because the chassis requires no high-RPM air intake fans, it is 100% immune to common facility killers like airborne dust, humidity, salt fog, and micro-debris. This eliminates core cleanroom filter maintenance costs and drives hashboard failure rates down close to zero.
-
Whisper-Quiet Data Center Ecosystem: Submerging the hardware inside industrial oil cooling arrays completely eliminates the deafening roar of traditional air ventilation grids. This gives operators the flexibility to deploy mega-watt scales without breaking localized residential acoustic zoning rules.
-
Rugged 3-Phase Power Architecture: Outfitted with an integrated enterprise power supply unit wired for 380V-415V standard input networks. This heavy-duty design minimizes overall line transformation losses while offering automated circuit safety cutoffs against localized phase grid drops.
