Advanced Compressor Technologies Solves Oversupply Problem

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine 

A Southern Indiana office furniture plant was wasting hundreds of dollars per day because its oversized VSD air compressor could not turn down low enough to match reduced demand after a shift to metal fabrication. To avoid drive faults, the plant vented compressed air to create false load. The audit revealed 300 cfm of wasted air—about $400 per day—and led to a redesigned system using a fixed-speed compressor for base load and a VSD unit for trim. The new configuration eliminated artificial demand and cut compressed air energy use in half, setting the stage for further savings through advanced sequencing, storage, and demand control.
