This past weekend I cleaned out some storage tubs that have been in my basement since I moved in. Within these tubs and boxes were all of my notes from college, along with all of my text books. Being any form of an engineering major means you keep all notes and books from college (I think). Among them was the manual for my graphing calculator. Even though I don’t graph anything on my calculator from college anymore, it still sits on my desk here and I use it to tell me how much money I am saving customers when they install our products. Along with calculating which Cabinet Cooler System they need.
The truth is, I don’t even need the calculator on my desk when I am looking at how much money an EXAIR Electronic Flow Control can save a customer. That’s because there is a free easy to use calculator right on our website. This calculator is going to allow you to put in how much air you are using, the percent of time the unit is on, how much you paid for the EFC and the compressed air, then it gives you how much air and money you save. The EFC Calculator will even tell you how many days it will take to recoup the price of the EFC.
Let’s look at an example of a 60″ Super Ion Air Knife that was installed to clean off bumper covers before a paint line. Not only did the customer save money by using the Super Ion Air Knife rather than the drilled pipes, they saved additional air and money by turning the compressed air off when a bumper wasn’t present. The following figures show the amount of money and air saved by implementing the EFC.
The Super Ion Air Knife was operated at 40 psig inlet pressure, this utilizes 102 SCFM of compressed air.
The process ran for 24 hours a day which equates to 1,440 minutes. There is a six second gap between each bumper, this means that you can reduce the on time by 37.5% just by turning the air off between bumpers.
The average cost to produce 1,000 SCF of compressed air is $0.25. The calculator shows the results below which include the pay back time for the EFC purchase. (CLICK it for a larger image)
As you can see, it will take a mere 84 days to reach a return on the investment of the EFC. The chart below (CLICK to enlarge) shows the math and cost savings when you also account for the amount of air saved by using the Super Ion Air Knife.
So if you have an intermittent compressed air application, by all means give us a call. We’ll help you figure out how much you’ll save by installing the EFC.
