The Bitcoin Miner S21+ Hyd. is engineered for miners seeking dependable hashrate output with advanced hydro-cooling technology. With a typical hashrate of 358 TH/s and power consumption of 5,370W, this unit is optimized for continuous operation in professional mining farms, hosting facilities, and data-center-style deployments.
Its hydro-cooling system enables consistent temperature regulation under sustained workloads, helping reduce thermal stress and maintain operational stability. Liquid cooling also allows for quieter operation and improved thermal efficiency compared to air-cooled miners when paired with appropriate cooling infrastructure.
Optimized for the SHA-256 algorithm, the S21+ Hyd. supports BTC, BCH, and BSV, offering flexibility across multiple proof-of-work networks. Designed for three-phase electrical systems, it integrates smoothly into industrial-grade power environments where reliability and scalability are critical.
Actual mining performance may vary based on power quality, cooling setup, ambient conditions, and network difficulty.
