Choosing the right type of master controller is essential for ensuring optimal efficiency and cost savings. Plant managers should keep a few key factors in mind when selecting a controller.
First, they should identify the proper performance indicators; these should be both measurable and impactful. Managers should also determine the energy needed for generating the required amount of compressed air. This is usually measured in kW/100 cfm, and should be measured and monitored regularly; this will allow operators to set benchmarks across systems in order to easily compare and analyze outputs. This, in turn, can aid in overall system-performance assessments, allowing operators to identify signs of trouble before serious issues occur.
Other factors — such as plans for plant expansion and the number of systems operating simultaneously — should also be carefully considered before choosing a specific master controller.
