ANTRACK AR21

ANTRACK AR21 is a compact hydro-cooling mining cabinet from Bitmain, made to run its liquid-cooled Antminers. It holds four standard Antminer Hydro units, or two U2 Hydro or U3 Hydro units, up to a 24 kW load. A pump in the cabinet circulates coolant to a separate fan cooler that is placed outdoors in a well-ventilated spot.

Notes

• Replace the coolant once its conductivity reaches 100 µS/cm; at first start-up it should be below 20 µS/cm.
• Wrong input voltage can damage the equipment.
• Installation must be carried out by a qualified electrician to local code.
