Built for Efficient Hydro-Cooled Deployment

A self-contained mining cabinet and external cooler pairing, engineered for professional hydro-cooled ASIC hosting with energy recapture.

🌡️

32 kW Capacity

Houses up to 4 hydro-cooled Antminer units (or up to 2 U3 hydro units), paired with an integrated heat pump rated for up to 32 kW of heating capacity.

♻️

80°C Heat Recovery

The integrated heat pump captures waste heat and outputs water at up to 80°C, suitable for reuse in heating applications - turning a cost center into a value stream.

❄️

Closed-Loop Hydro Cooling

A dedicated water pump and 30kW plate heat exchanger keep hosted miners at a stable, optimal temperature for maximum uptime.

🛡️

12-Month Warranty

Full manufacturer warranty covering hardware issues and defects.

🔌

Three-Phase Power Ready

Operates on 380-415V AC three-phase power, with the mining cabinet rated up to 63A and the external cooler up to 21A.

📦

Modular Design

Ships as a mining cabinet plus a separate external cooler unit with integrated heat pump, simplifying transport and on-site installation.

Bitmain AR1902 Hosting Capacity

Revenue from an AR1902 deployment comes from the 4 hydro-cooled Antminer units it hosts (e.g. S19 XP+ Hyd at 293 TH/s, or newer S21/S23 Hyd series), plus any value recovered from its 80°C heat output.

AR1902 FAQ

Everything you need to know about the Bitmain AR1902.

The AR1902 houses up to 4 hydro-cooled Antminer units (or 4 U2 Hydro units, or 2 U3 Hydro units), paired with an integrated heat pump rated for up to 32 kW of heating capacity.
The AR1902 includes an integrated heat pump that recovers waste heat and outputs water at up to 80°C, suitable for reuse in heating applications, whereas the standard AR1901 model only dissipates heat.
A closed-loop water pump and 30kW plate heat exchanger circulate coolant through the hosted miners, then reject heat via an external cooler with an integrated R290 heat pump.
The Bitmain AR1902 comes with a standard 12-month manufacturer warranty covering hardware issues and manufacturing defects.
Designed for Bitmain's hydro-cooled Antminer lineup, including the S19 XP+ Hyd (293 TH/s), S21 Hyd, S21+ Hyd, S21e Hyd, S23 Hyd, and related U2/U3 hydro variants.
