The Bitmain Antminer S21e Hyd delivers 310 TH/s of SHA 256 hashrate at 5,270W through water cooling, achieving 17.0 J/TH efficiency. This is the higher spec variant of the S21e Hyd duo, sharing the same chassis as its 288 TH/s sibling but with top binned chips for more output. At 17.0 J/TH, the S21e Hyd is a mid generation machine. Current flagships like the S23 Hydro achieve 9.5 J/TH. But not every operation needs or can afford top tier hardware. The S21e Hyd fills the mid range bracket for facilities that already have hydro cooling infrastructure and want to expand hashrate at a lower acquisition cost per unit than the S23 series. 380 to 415V three phase power. This is industrial… electrical specification, standard in data centers and purpose built mining facilities. Not compatible with single phase residential or commercial power without conversion equipment. 50 dB noise through water cooling. Significantly quieter than the 75 dB air cooled S21 variants. 12.8 kg at 410 x 170 x 209mm. Ethernet management through Bitmain's established firmware interface. operates across 5 to 45C ambient with standard humidity tolerance. Mines Bitcoin, Bitcoin Cash, and all SHA 256 proof of work coins. For facilities already running Bitmain hydro infrastructure, the S21e Hyd integrates directly into existing cooling loops and management systems. No new software, no new training, no compatibility issues. This operational simplicity is a significant factor for large operations where every machine must fit the same management and maintenance workflow.
310 TH/s SHA 256 at 5,270W with hydro cooling. 17.0 J/TH efficiency. The higher spec S21e Hyd variant with top binned chips sharing the same chassis as the 288 TH/s model. Mid generation pricing for facilities expanding hydro cooled hashrate below S23 tier costs. 380 to 415V three phase, 50 dB, 12.8 kg. Bitmain firmware interface with Ethernet management. Requires existing water cooling infrastructure. Mines all SHA 256 proof of work coins. Direct integration into existing Bitmain hydro infrastructure. Same management software, same cooling… connections, same maintenance workflow as other Antminer hydro units. Operational simplicity matters at scale where every machine must fit the same management stack. 5 to 45 degrees Celsius at 5 to 95 percent humidity. Operational simplicity for large facilities: same Bitmain management software, same cooling connections, same maintenance workflow as other Antminer hydro units. No new software or training required to integrate S21e Hyd units into existing Bitmain fleets.
Our mining specialists can help you find the perfect miner for your setup and budget.
