Quad Drives Compressed Air Efficiencies at 1.7 million-square-foot Printing Plant
The Sussex plant operates no less than 22 air compressors to keep pace with demand, which ranges from 11,000 to 16,000 cfm. The water-cooled, rotary screw air compressors, which are predominately 200-horsepower (hp) machines, in addition to a select number of 100-hp and smaller units, are strategically located throughout the sprawling complex to consistently deliver clean dry air where needed. A total of 18 air compressors are fixed-speed machines while the remainder are Variable Speed Drive (VSD) machines. The plant’s system also includes 26 refrigerated dryers, as well as various receiver tanks.
