BITMAIN Antminer S21 XP Immersion 300T Bitcoin Miner

Not every operation runs on air. If you’re building or scaling an immersion-cooled setup, the Antminer S21 XP Immersion is purpose-built for exactly that environment. With 300 TH/s of SHA-256 hashing power and a design optimized for liquid submersion, this is a miner that thrives where air-cooled units tap out.

No fans, no thermal throttling, no noise complaints. Just clean, stable output that you can count on when your rigs are running around the clock.

Antminer S21 XP Immersion Performance Metrics

300 TH/s isn’t the biggest number on the market, but paired with immersion cooling it punches above its weight. Operating at 4050W with an efficiency rating of approximately 13.5 J/TH, the S21 XP Immersion delivers competitive hashrate without the thermal overhead that kills air-cooled hardware over time.

It’s optimized for the SHA-256 algorithm, making it a natural fit for Bitcoin mining operations that prioritize long-term stability over short-term peak output. Understanding electricity costs becomes crucial when evaluating the true operational efficiency of this immersion-cooled unit.

Why Immersion Cooling Changes the Game

Submerging your miners isn’t just a cooling flex – it’s an infrastructure decision. The S21 XP Immersion is built to take full advantage of liquid submersion, giving you tighter thermal control, higher deployment density, and hardware that lasts longer under continuous workloads.

If you’re running a professional BTC mining facility or building one out, this unit fits cleanly into a scalable, future-ready setup. Many operators find that hosting facilities with immersion cooling infrastructure offer the best environment for maximizing these miners’ potential.
