The Antminer T21 (180T) is Bitmain’s answer to the needs of large-scale data centers. While the S21 focuses on absolute efficiency, the T21 focuses on electrical resilience and thermal endurance. It is specifically designed to thrive in high-ambient temperature regions, such as the Middle East or Southern USA, where operating at up to 45°C is a requirement.
The Three-Phase Power Advantage
Unlike standard residential miners, the T21 utilizes a P33-P33 power interface and requires a 380V–415V input. This three-phase architecture offers several critical benefits for professional miners:
-
Phase Balancing: Automatically balances electrical load across phases, reducing the risk of circuit overloads and equipment damage.
-
Higher Voltage Resilience: The system is inherently more stable against voltage spikes and grid fluctuations, ensuring your 180T hashrate stays online longer.
-
Reduced Cable Loss: Higher voltage means lower current for the same power draw, leading to less heat generation in your facility’s wiring.
Optimized for High-Heat Environments
The T21 is engineered for “NEM” (Normal Energy Mode) and “HEM” (High Energy Mode) flexibility:
-
Thermal Endurance: Built to operate safely at ambient temperatures up to 45°C (113°F), making it one of the most rugged air-cooled units in Bitmain’s 2026 catalog.
-
Efficient Airflow: The chassis is wider than the S19 series, allowing for massive quad-fan airflow that keeps the internal ASIC chips within optimal ranges even under heavy load.
-
Market Fluctuation Protection: As part of Bitmain’s T-series lineage, this unit offers a competitive entry price, allowing for a faster ROI when Bitcoin difficulty or price fluctuates.
