Fan Control for the Glass Industry Using Static Induction Motor Drives

The glass industry uses large fans requiring high horse- power drives in several glassmaking processes. For example, forming fans are used to manufacture fiber glass insulation and mold cooling fans are employed in the manufacture of glass containers. Substantial electrical energy savings can be achieved using adjustable speed fan control rather than damper control. Other noneconomic benefits also accrue to the user of solid-state drives for these applications.
