With a mining power of up to 24 TH/s and efficiency of up to 75 J/TH, the Shield offers impressive performance.

  • Protection & Durability: The air and dust filters of the Shield provide effective protection against dirt accumulation within the device (even in storage and production halls with high dust levels), thereby safeguarding the internal hardware and extending the lifespan of the heater. The galvanized sheet metal ensures longevity and corrosion resistance, ensuring reliable operation of the heater under various conditions.

  • Savings Potential: The savings potential of the heater depends on individual energy costs and market prices for calculations.
