Compressed air fail: One little button
A farm implement manufacturer had a system of three large 150-hp compressors that were air-cooled lubricant-injected screw compressors. To control these compressors β two of which were needed for peak duty on any given day β the compressors were set up in a cascaded pressure band arrangement, with each unit running in load/unload mode. In […]

Six simple ways to improve your compressed air system
By Ron Marshall Compressed air is one of the most expensive ways to supply energy to facility tools and equipment. This is due to the inherent inefficiencies in the process of compressing air β the biggest product is heat and the secondary output is compressed air. While this is disappointing, there are still things that […]
Why is compressor control important?
When controlling screw compressors, the goal is to try to keep all the running compressors fully loaded except one. And the one running partly loaded (called trim) is selected as the one having best part load efficiency characteristics. When there are only two or three compressors in a group, it is quite easy to set […]
