Antminer S21j XP Hyd Description

The Bitmain Antminer S21j XP Hyd is a high-efficiency ASIC miner for SHA-256 Bitcoin mining, delivering up to 495 TH/s with 12 J/TH efficiency.

Designed for next-generation hydro cooling mining infrastructure, this model focuses on higher energy efficiency and stable long-term performance for large-scale BTC mining farms.

Unlike traditional air-cooled mining machines, the S21j XP Hyd uses a liquid cooling loop that transfers heat directly from the ASIC chips, allowing the miner to maintain consistent temperatures and stable hashrate under continuous workloads.

Water cooling also enables higher rack density and container deployment, making it ideal for data-center-style mining farms and hydro cooling containers where space, efficiency, and uptime are critical.
