By catching early warning signs of fan motor faults, Elkem avoided costly downtime and environmental risks, while reducing alarm overload for the team.
in lost revenue avoided by catching one fan fault early
critical exhaust fans monitored for environmental control
sensors, reviewed in weekly checks by HD's team
Elkem’s ferrosilicon plant in Iceland partnered with HD and Viking Analytics to monitor nine critical exhaust fans—vital for environmental control and production continuity. Previously overwhelmed by alarms and raw sensor data, HD adopted Viking’s AI-powered vibration analysis platform to focus only on high-priority issues. With 42 sensors and weekly checks, the team now detects faults earlier and avoids unnecessary stops. In one case, Viking Analytics helped prevent a failure that could have cost Elkem up to €100,000 in lost revenue.
Fan failures triggered environmental risk and costly downtime; too many alarms overwhelmed HD’s team.
Installed sensors and used MultiViz to focus only on the top 2–5% of risky assets.
Prevented critical failure — avoiding up to €100K in losses.
With Viking Analytics, we can quickly spot which assets need attention—no more digging through endless charts. It’s made our work with Elkem much more focused and effective.
