Data You Should Be Collecting

The best method for ensuring proper maintenance is keeping a record of your compressed air system’s performance. Checking regularly for important aspects of the system and then keeping a log of those factors will give you an idea of when a system is running properly and when it’s not. It can also give you insights into operation that could end up saving you some money. Many modern systems come with sensors that connect to computers and log the important data automatically making record-keeping a breeze. Pressure and flow are important aspects of the system that need to be measured but there are others as well.

Dew Point

Moisture can be an issue for any type of compressed air system so knowing when and where moisture is most likely to occur can be very important depending on the processes involved. As the dew point can change depending on season it’s important to measure and log this data regularly to make sure that any changes that need to be made can be done so before it becomes a problem.


Proper monitoring of system performance – specifically compressors, coolers, and dryers – should include the measurement and recording of temperature. Areas that should have their temperature checked include: Inlets and outlets for cooled compressors and dryers, dryer and condensate, lubricants, air going into the compressor and the air discharged from it, bearings, and many other areas. Overheating or cooling can create significant problems so keeping an eye on temperature is critical.


This is the most important measurement when it comes to cost savings. Knowing how much power your plant is using means you’ll be able to see spikes or trends that you can to use to make modifications to increase reliability and decrease consumption. Proper electrical measurement will enable you to determine the cost of the system as a whole as well as any specific components enabling you to replace energy hogs with higher-efficiency models on the most cost-effective basis. As a rule, measure electrical use weekly – or after any new component is installed – and compare the results with previous tests. If there’s any fluctuations or problems you’ll be able to detect them quickly.

Collecting data is something every good plant manager should do to make sure everything is running as smoothly as possible without unnecessary costs. If you’d like to have someone take a look at your data or you feel a full energy audit with across-the-board measurements is called for contact the experts at CED today.
