    Verified seller

    The S21 Immersion is designed for liquid immersion cooling setups, delivering 400 TH/s at 13 J/TH while drawing 5200W. Immersion cooling submerges the miner in dielectric fluid, improving heat transfer efficiency and potentially extending component lifespan compared to air or hydro systems. Requires specialized immersion tanks and fluid management infrastructure. Near-silent operation with excellent thermal density. Purpose-built for professional immersion facilities. Note: requires dedicated facility infrastructure beyond standard mining setups.

    Key Features

    • Industry-leading 13 J/TH energy efficiency
    • Powerful 400 TH/s hashrate for maximum profitability
    • Advanced thermal management with Immersion-cooled
    • Easy setup and management via web interface

    Shipping crate doubles as temporary stand

    Pro tip: the wooden shipping crate my Antminer S21 Immersion came in works as a temporary stand while you sort out permanent mounting. It's sturdy enough and keeps the unit off the floor for airflow. Practical packaging from MinerHaolan.

    Built for real industrial conditions

    I've seen plenty of "mining containers" that are basically shipping boxes with fans bolted on. The Antminer S21 Immersion is nothing like that. This is properly engineered industrial equipment — fire suppression, environmental controls, redundant systems. It's built like infrastructure, not a hack job.
