Antminer S21+ HYD 395T – Hydro-Cooled SHA-256 Mining for Professional Operations
The Antminer S21+ HYD 395T is a hydro-cooled ASIC miner designed for efficient Bitcoin mining. Built for industrial mining farms and infrastructure-heavy deployments, this model combines 395 TH/s of hashrate, 5,925 W power consumption, and 15 J/TH energy efficiency to support stable 24/7 operation and long-term mining performance.
This model is designed for Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV) and uses hydro cooling to deliver more advanced thermal management than traditional air-cooled miners. That helps maintain consistent performance, reduce thermal stress on components, and support stable operation in professional mining farms and data-center-style environments.
