The Antminer S21+ Hyd is a hydro-cooling miner from Bitmain, known for its high performance and energy efficiency. Here are its key features:
1. Hashrate: The S21+ Hyd boasts a typical hashrate of up to 319 TH/s, making it one of the most powerful miners in its class.
2. Energy Efficiency: With a power efficiency of just 15.0 J/T at 35°C, the S21+ Hyd is extremely energy-efficient, which is crucial for mining profitability.
3. Advanced Cooling System: The hydro-cooling system of the S21+ Hyd includes two water pumps and a tank, which effectively reduces the working temperature and noise of the miner.
4. Environmental Adaptability: The S21+ Hyd is designed to operate in environments with a maximum ambient temperature of 45 degrees Celsius, allowing for global operation without worries about overheating.
5. Networking Connection: It features an RJ45 Ethernet 10/100M connection mode for reliable network connectivity.
6. Coolant Requirements: The miner requires an inlet coolant temperature between 20 to 50°C, a coolant flow rate of 8.0 to 10.0 L/min, and a coolant pressure of ≤3.5 bar.
7. Working Coolant: It is compatible with antifreeze, pure water, and deionized water, with specific pH value ranges for each type of coolant.
8. Power Supply: The S21+ Hyd requires a 3-phase power supply with an input voltage of 380~415 Volts and an input frequency range of 50~60 Hz.
These features make the Antminer S21+ Hyd a competitive choice for miners seeking high-performance and energy-efficient mining equipment that can operate in a wide range of environmental conditions.
