Key Features & Performance Highlights
-
Competitive $19.0 \text{ J/TH}$ Global Efficiency: The T21 utilizes Bitmain’s refined semiconductor node layout to achieve a highly efficient footprint of just $19.0 \text{ Joules per Terahash}$. This competitive energy consumption helps stabilize operations and shields net profits during shifting utility cost cycles.
-
Industry-Leading High-Temperature Resiliency: Unlike standard miners that require strict climate control, the T21 is uniquely engineered to operate in ambient temperatures reaching up to $45^{\circ}\text{C}$ ($113^{\circ}\text{F}$). This specialized thermal resilience makes it perfect for facilities utilizing ambient air-cooling without expensive industrial HVAC systems.
-
3-Phase Power Configuration: Outfitted with an integrated, enterprise-class smart power supply unit running on 380-415V input. This design drastically cuts down electrical conversion line losses while providing automated protection thresholds against voltage drops and grid imbalances.
-
Heavy-Duty Cross-Flow Ventilation: Equipped with four high-RPM heavy industrial fans configured in a parallel push-pull wind tunnel layout. Heat is swiftly drawn out across the high-density aluminum heatsinks, maintaining optimal chip junction temperatures for continuous 24/7 computation.
