About this model

The Antminer U3S21EXPH is Bitmain's most powerful container system: 860 TH/s at 11180W. It combines three next-gen units on the BM1370 chip with a shared liquid circuit. At 13 J/TH efficiency, it's an industrial solution for maximum productivity.

U3S21EXPH repair is top-tier complexity work. Each unit contains BM1370 hashboards, and the shared hydraulic system requires precise balancing and maintenance. We have experience with container systems from both generations.

Common issues

One unit running at reduced hashrate — BM1370 chip degradation or water block contamination

Total hashrate below 800 TH/s — issue at individual hashboard or hydraulic level

Coolant leak in distribution manifold — seal wear under high pressure

Uneven temperature between units — flow imbalance or clogged filter

One unit's control board not responding — firmware or network controller crash
