One of the defining features of the Antminer T21 190 TH/s is its strong environmental adaptability. It is adjustable from NEM to HEM mode, which means it can switch modes for optimized performance. Its tolerance to ambient temperatures up to 45°C makes it particularly suitable for high-temperature regions such as the Middle East. This miner guarantees outstanding performance even in extreme conditions, ensuring continuous, reliable operations.

Incorporating a superior cooling system, the Antminer T21 dissipates heat effectively to maintain optimal performance. This makes it one of the best choices for miners looking to invest in equipment that delivers consistent results, regardless of environmental challenges.
