Business Challenge
Operators struggled to consistently achieve ultra-high purity levels (10 ppb) required for semiconductor-grade products. Due to concerns over potential purity loss, they were reluctant to adjust ASU loads, especially during fluctuating demand. This led to frequent product venting and yield loss, as manual control lacked the precision and confidence needed for real-time optimization
