A good exercise for any compressed air system is to find and fix compressed air leaks. And if the system compressors are well controlled, some significant energy savings can be gained by doing leak audits and repairs on a regular basis; this is generally recommended quarterly. Some excellent tools to use in the process are […]

A wood products company had an aging heatless 1,000 cfm desiccant air dryer, being used to condition the compressed air produced by two 100-hp compressors in their processing facility. After working for many years, the dryer controller failed and had to be replaced. Replacement parts could not be found, so the local electricians came up […]

From time to time, compressed air auditors find air-cooled air compressors located in small rooms where the ventilation is inadequate. Most of the time, in properly designed rooms, the heat the compressors produce is ducted out of the room through metals ducting — often, it will be directed to cool areas of the plant in […]

A mining complex was experiencing low pressure events — even though its 14 large compressors were all running. The pressure was adequate during most of the day, but during peak demand times, the pressure sagged to unacceptable levels. This, of course, caused complaints from the workers. The pressure settings of the compressors were already set […]

When doing a compressed air audit, it is always recommended to measure the important parameters of the system and analyze the data carefully. Typically, pressure and power (or amps) are monitored, but in some cases measurement of flow comes in handy. In the case of a large plumbing component manufacturer, the installation of flow meters […]

A compressed air auditor was assessing a compressor and dryer installation within a compressor room and noticed something strange. On a large air dryer, the outlet flange was of 6-in. size, yet the piping used to connect the compressors and filters to the air dryer was only 4-in. Further to this, the long piping link […]

A compressed air auditor visited a large mine and was asked to look for areas of improvement. The mine’s manager was interested in reducing the electrical consumption and had a hunch that the compressed air system was a good item to investigate. The facility was a very mature site, so there were many large compressors […]

Recently, a compressed air auditor ran across a newly rebuilt compressor at a wood products company. The unit was cleaned up nicely and had a shiny new air end due to a rebuild — but because the unit had obsolete controls, this compressor continued to run very inefficiently. Saving money by rebuilding this compressor was […]

Quite often, people are surprised when they measure an air compressor and find the motor is consuming more than rated amps. One of the unfortunate things about the industry is that it is common to see motors are being stretched into the “service factor” in order to get more cfm out of a given compressor […]
