Design & Hashing Power: The design is inspired by a classic heater and made of high-quality steel not only gives the heater a fitting appearance in the industry but also ensures robustness and durability. 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. Calculate your individual heating cost savings now with our profitability calculator or contact us directly via the contact form for a personal and individual calculation.

Installation & Assembly: The heater can be mounted on the wall in addition to the traditional floor-standing setup. Special brackets are built into the top plate for this purpose. The Shield is particularly well suited for construction containers.

Additionally, the Shield is CE-compliant and meets the highest safety standards.

Mining Pool: The built-in refurbished Antminer S9 units are compatible with various mining pools and can be freely selected by the user.

Operating System: The Shield comes pre-installed with the Braiins OS+ operating system, which provides automatic optimization and increases efficiency by up to 30 %. This autotuning feature allows for improved cash flow and a higher hash rate of up to 30 % with the same power consumption.
