EnSave, an energy auditing company based in Richmond, Vermont, recently performed compressed air audits at two facilities of a leading U.S. steel manufacturer. Both plants are mills that melt, cast, and roll steel to produce a variety of products, including: rebar, merchant bar, steel flats, rounds, fence posts, channel bar, steel channels, steel angles, structural angles and structural channels. These products are used in a diverse group of markets, including: construction, energy, transportation and agriculture. Compressed air is provided at 100 psig in both plants for a variety of applications — from optical sensor cooling to pneumatic cylinders for stacking finished products.
Nissan North America operates on a massive scale. The company’s powertrain assembly plant in Decherd, Tennessee, alone encompasses 1.1 million square feet, and manufactures engines for 14 different vehicles. The facility also handles crankshaft forgings, cylinder block castings, and other machining applications. Over the course of one year, the powertrain plant churns out approximately 1.4 million engines, an equal number of crankshaft forgings, and 456,000 cylinder block castings.
A major Midwestern aluminum plant was experiencing dwindling compressed air capacity, primarily due to air leaks. If those capacity issues went unresolved, the facility would have needed rental compressors to keep up with demand. Instead, they turned to flow metering to identify and fix the leaks. In this article, they share their solutions with others who may be having similar difficulties.
