Compressed Air Challenge: Avoid VSD-Compressor Control Gap

By Ron Marshall, CET, CEM for the Compressed Air Challenge (CAC) One of the hottest topics in the compressed-air energy-efficiency field is the variable-speed-drive (VSD) screw compressor. Since this unit’s acceptance in the industry several years ago, all major manufacturers have developed a line of compressors that control compressor output pressure by varying the speed of the compression element. […]

Compressed Air Challenge: Show Me the Money

By Ron Marshall, CET, CEM for the Compressed Air Challenge (CAC) With compressed air system efficiency, ignorance is not bliss. Conditions can slowly develop over time that erode system efficiency. And because most compressed air systems have little in the way of monitoring instrumentation, key performance indicators that are important to keeping systems running in a cost-effective manner can’t be […]

Compressed Air Challenge: Put Your Compressed Air System to Sleep

By Ron Marshall, CET, CEM for the Compressed Air Challenge (CAC) Just like turning out the lights when you leave a room, a good energy-efficiency strategy for compressed air is to turn the equipment off when not required. Leaving the equipment running will waste energy, increase maintenance costs and shorten its life cycle. Industrial compressed […]

Compressed Air Challenge: Maintaining Peak Compressed Air Efficiency

By Ron Marshall, CET, CEM, for the Compressed Air Challenge (CAC) The compressed air system is often ignored when it comes to maintenance. Under normal conditions, the system’s compressors, dryers, filters and pipes draw little attention, in part because they are often located in a far corner of the plant. Yet when there is trouble, […]

Compressed Air Challenge: Why Is Your Pressure So High?

By Ron Marshall, CET, CEM for the Compressed Air Challenge (CAC) There was a day when most air compressors were rated at 100 psi: Rarely did general plant compressed air systems exceed this threshold. Over the years, however, plant pressures have climbed—and this has cost industrial customers a bundle. A good exercise for anyone involved […]

Overcoming Your Challenges: Efficient Compressed Air Piping

By Ron Marshall, for the Compressed Air Challenge (CAC) Getting your compressed air to flow where it needs to go requires a transmission system—a network of piping that connects your compressors to the end-uses. This piping system can have a big effect on the overall efficiency of your equipment. Around the 100 psi range, for every […]
