TH\/s with 12 J\/TH efficiency.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<p>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.<\/p>\n<\/div>\n<\/div>\n<div class=\"elementor-element elementor-element-f984a8f color-scheme-inherit
