The 20-Slot 200kW Hydro Cooling System is a specialized liquid cooling solution engineered specifically for Antminer 2U models. As dedicated 2U hydro infrastructure remains rare across the market, this standardized 42U rack delivers a purpose-built solution—housing up to 20 units of Antminer S23e U2H, L9 Hyd 2U, and L11 Hyd 2U with an ultra-low PUE below 1.05.
Pairing an indoor hydro cabinet with a high-efficiency outdoor dry cooler, the system guarantees stable thermal performance across demanding climates. The integrated CDU automatically balances fluid circulation, keeping chip temperatures optimal to eliminate heat-induced throttling and ensure full-hashrate stability.
Factory pre-wired and pre-plumbed for true plug-and-play commissioning, the system minimizes on-site deployment time. It also supports flexible custom configurations and modular multi-rack expansion, allowing operators to seamlessly scale their 2U hydro capacity as their mining operations grow.

Achieves an exceptional PUE rating under 1.05, minimizing auxiliary cooling electricity consumption so nearly all input power is directly converted into active computing hashrate, slashing operating power overhead.
Pairs with a heavy-duty outdoor dry cooler featuring dual high-volume fans and adiabatic wet curtains, guaranteeing reliable heat rejection even during severe summer heat waves with minimal water usage.
Integrates a dedicated CDU with a 17.3 m³/h circulation pump, intelligent PLC monitoring, a 20-channel breaker PDU, and a gigabit network switch for seamless, unified system management.
Purpose-built to address the rare market availability of 2U hydro infrastructure, delivering 20 custom-fitted slots in a 42U frame tailored specifically for Antminer S23e U2H, L9 Hyd 2U, and L11 Hyd 2U miners.
The cooling architecture is designed for phased deployment, allowing additional racks, CDU capacity, or heat dissipation equipment to be incorporated as mining capacity increases and site requirements evolve.

Which miners are compatible with this 20-slot hydro cooling rack?
The system is purpose-built and factory-matched for the Antminer 2U hydro series, providing 20 standardized slots engineered specifically for models including the Antminer S23e Hyd 2U, L9 Hyd 2U, and L11 Hyd 2U. The 42U cabinet's internal mounting rails, quick-connect water manifolds, and dedicated 20A circuit breakers are precision-configured to match the exact chassis dimensions, power inputs, and thermal dissipation requirements of these 2U units out of the box.
Does the outdoor dry cooler consume water, and how do the wet curtains work?
Under standard ambient temperatures, the system operates as a closed-loop dry cooler with zero water consumption, circulating coolant without evaporative loss. The integrated adiabatic wet curtains serve as an optional high-temperature booster. During peak summer heat waves (when ambient air exceeds 35°C–40°C), wetting the curtains pre-cools the incoming air through evaporation, maintaining high heat transfer efficiency and preventing miner thermal throttling with minimal water usage.
What are the electrical supply and transformer requirements for this system?
The system requires a 380V–415V AC 3-phase power supply (50/60Hz). Total power consumption is approximately 210 kW (covering 20 high-power 2U miners plus the cooling pumps and dry cooler fans). The indoor rack comes pre-wired with an integrated industrial PDU featuring twenty 20A circuit breakers (20A × 20) for individual slot protection. Operators typically require a dedicated 250 kVA to 315 kVA transformer (or equivalent facility headroom) to support continuous full-load operation.
How are the indoor 42U cabinet and outdoor dry cooler connected? What is the maximum piping distance?
The indoor rack connects to the outdoor dry cooler via two insulated fluid pipes (supply and return) powered by the CDU’s integrated 17.3 m³/h circulation pump. The standard recommended piping distance between the indoor cabinet and outdoor cooler is within 10 to 15 meters (30–50 ft) using DN50/DN65 pipes to ensure minimal pressure drop and optimal flow rates. If your site requires longer pipe runs, our engineering team can provide auxiliary booster pump guidance.
Can multiple 20-slot racks be scaled or linked together for larger warehouse deployments?
Yes, the system is fully modular and scalable. Operators can deploy individual stand-alone units (1 rack + 1 dry cooler) or parallel multiple 42U racks together in warehouse environments. For multi-rack deployments, multiple indoor cabinets can either retain dedicated dry coolers for independent redundancy or tie into a centralized high-capacity outdoor cooling loop, allowing your 2U hydro fleet to expand smoothly from 20 units to hundreds of units.
What safety protections and alarms are integrated into the CDU?
The all-in-one CDU is equipped with an automated PLC control module that monitors key hydraulic parameters in real time. It features a low-liquid-level alarm to detect coolant loss, an automated blowdown/drainage alarm for maintenance, and loop pressure/temperature tracking. If an abnormal pressure drop or critical fluid temperature is detected, the system triggers alerts to protect ASIC hashboards and electrical components from thermal and dry-run damage.
