20-Slot 200kW liquid cooling system for Antminer 2U

The system is purpose-built for Antminer 2U hydro models :

• Antminer S23e U2H – Latest generation 2U hydro miner

• Antminer L9 Hyd 2U – High-performance Scrypt 2U miner

• Antminer L11 Hyd 2U – Next-gen Scrypt 2U miner

Dedicated 2U hydro infrastructure remains rare across the market. This standardized 42U rack is engineered specifically for 2U hydro miners, filling a gap that general-purpose hydro containers and cabinets do not address. Operators running S23e U2H, L9 Hyd 2U, or L11 Hyd 2U units now have a purpose-built, plug-and-play cooling solution.

The system achieves an ultra-low PUE below 1.05 . This means nearly all input power is converted into active computing:

• Minimal auxiliary cooling overhead

• Lower operating costs per hashrate

• Sustainable mining through optimized energy utilization

For context, air-cooled facilities typically operate at PUE 1.10-1.20, meaning 10-20% of power is wasted on cooling. The <1.05 PUE represents a significant efficiency advantage.

The integrated CDU (Cooling Distribution Unit) automatically balances fluid circulation :

• Optimal chip temperatures maintained continuously

• Eliminates heat-induced throttling

• Full-hashrate stability 24/7

The CDU circulation pump delivers 17.3 m³/h flow rate, ensuring adequate coolant distribution across all 20 miner slots.

Yes. The system pairs an indoor hydro cabinet with a high-efficiency outdoor dry cooler equipped with adiabatic wet curtains . This ensures :

• Reliable heat rejection even during summer heat waves

• Minimal water usage – sustainable in water-conscious regions

• Stable performance across diverse environmental conditions

The adiabatic wet curtain system provides additional cooling capacity during peak ambient temperatures, maintaining performance when dry cooling alone would be insufficient.
