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

Best buying experience
Buying my Antminer S21 Immersion from MinerHaolan was the best purchasing experience I've had for mining equipment. From inquiry to delivery, everything was smooth and professional.
Fair price, excellent product
MinerHaolan offers the Antminer S21 Immersion at a fair price and delivers an excellent product. No price gouging, no hidden costs. Just honest value for money.
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.
Smart investment for my farm
Adding the Antminer S21 Immersion was a smart investment for my farm. The cost was reasonable and the output has been excellent. My accountant is happy with the numbers.
