The Bitdeer Sealminer A2 232T is the centerpiece of Bitdeer’s self-developed mining hardware line. Leveraging the company’s deep industrial expertise, the A2 series was designed to solve the most common pain points of modern miners: efficiency, heat management, and long-term reliability. The 232 TH/s variant represents a high-bin, optimized model that strikes the perfect balance between raw power and electrical economy.
Next-Gen 4nm SEAL01 Technology
At the heart of the Sealminer A2 is the SEAL01 chip, manufactured using TSMC’s advanced 4nm process. This architecture allows for a significantly higher transistor density compared to 5nm or 7nm alternatives, resulting in:
-
Lower Power Leakage: Maximum hashrate with minimal wasted energy.
-
Thermal Efficiency: The chips operate at lower relative temperatures, reducing the strain on the cooling system.
-
Superior Stability: Designed for 24/7 industrial loads with a focus on consistent uptime.
Optimized for ROI: 16.5 J/TH Efficiency
With a power consumption of approximately 3828W, the Sealminer A2 232T maintains a competitive efficiency ratio of 16.5 J/TH. This places it firmly in the elite category of SHA-256 miners, allowing operators to remain profitable even as network difficulty increases. Its refined power supply unit (PSU) supports a wide voltage range (220V-277V), making it compatible with both international industrial grids and residential high-voltage setups.
Industrial Build Quality
Bitdeer has prioritized a “low-noise signature” and high-static pressure cooling. The four high-speed fans are orchestrated by an intelligent control board that adjusts RPM based on real-time sensor data, preventing thermal throttling and extending the lifespan of the hash boards.
