Matching the Supply and Demand in a Compressed Air System

By Bob Wilson, PEMCO Services for the Compressed Air Challenge®

Production processes get their energy from the air stored at higher pressure in the piping distribution system. The air compressors simply replenish the air that is consumed. It is an important distinction to make. The energy input in compressing the air is supplied to the connecting pipes for delivery to the various demands throughout the facility.

A View From Europe. Challenge Convention: Compressor Management Systems Applied in the Automotive Industry

By Nicolas De Deken, EnergAir

“First there are the old conventions. The majority of compressor houses still employ fixed speed compressors and a cascaded pressure switch control system. This arrangement will be familiar to many, but it is outdated and inefficient, and needs to be changed. There is a comfort factor with familiar technology, which is exacerbated by constant time pressure due to other day-today responsibilities and a lack of information and good advice on what can be achieved.”

Tier 1 Automotive Plant Saves $218,000 in Energy Costs

By Hank Van Ormer, Air Power USA

A Tier 1 automotive plant was spending \$364,259 annually on electricity to operate their compressed air system. This figure was expected to increase as electric rates were forecasted to rise from their current average of 7.16 cents per kWh. Our firm, Air Power USA, conducted a full supply and demand-side compressed air system assessment. The set of projects recommended by the assessment, would reduce these energy costs by \$218,670 or 60%.

The “Dirty Thirty” – Discovering Pressure Differential at the Far End

By Ron Marshall for the Compressed Air Challenge®

Much attention and expense is often directed towards optimizing compressor control, clean-up equipment, system pressure / flow control and main system piping in an attempt to maintain adequate and stable pressure at the end use. Often forgotten are the components of the distribution system between the main system header and the end use.
