How zinc smelter Nyrstar got 800% ROI in 11 months
Continuous monitoring on the smelter's critical drivetrains caught faults early, including a 10 kV rectifier cable fault that would have caused over €1 million in equipment damage.

Six early alerts to degrading fans save up to 12 hours and €96k in unplanned downtime
Exhaust fans on a wood panel line were degrading unnoticed. Six early alerts let the plant fold every repair into a scheduled stop.
