EXAIR Products Qualify for Energy Rebates

Published on by Jordan T ShouseLeave a comment

The use of compressed air can be found in almost any industry and is often referred to as a “fourth utility” next to water, gas and electric. The generation of compressed air accounts for approximately 1/3 of all energy costs in an industrial facility, in many cases, it’s the largest energy user in an industrial plant. With an average cost of $ 0.25 per every 1,000 SCF used, compressed air can be expensive to produce so it is very important to use this utility as efficiently as possible.

Many utility companies recognize the benefit of using engineered products to reduce compressed air usage, like the ones manufactured by EXAIR, and offers rebate incentives for making a switch. Duke Energy, who supplies power to sections of North Carolina, South Carolina, Ohio, Kentucky, Indiana and Florida offers several “Smart $aver Rebates” that focus around the generation and use of compressed air.

Duke Energy’s Smart Saver Program

However the best place to look at your states available programs is the DSIRE database. DSIRE is the most comprehensive source of information on incentives and policies that support renewable energy and energy efficiency in the United States. Established in 1995, DSIRE is operated by the N.C. Clean Energy Technology Center at N.C. State University. Follow the link above to read about the history of DSIRE, the partners on the project, and the research staff that maintains the policy and incentive data in DSIRE.

The Process is pretty easy! Visit https://www.dsireusa.org/ and type in your Zip Code!

https://www.dsireusa.org/

After you get your results, search some key words, Like “Industrial” “Energy” “Commercial” “Energy Efficiency” “Compressed air”

https://www.dsireusa.org/

Here you can see the two Programs that came up for 46077, you can then click the program name and it will take you a information page with the programs website and information!

Here at EXAIR, much of our focus is to improve the overall efficiency of industrial compressed air operating processes and point of use compressed air operated products. If you’d like to contact one of our application engineers, we can help recommend the proper engineered solution to not only save on your compressed air usage but also assist with possible energy rebates available in your area.

EXAIR’s Efficiency Lab Shows How Much Compressed Air You Can Save

Published on by Jordan T ShouseLeave a comment
The EXAIR Efficiency Lab

EXAIR has been manufacturing compressed air products since 1983, and we created a culture of making high quality products that are safe, effective, and very efficient.  Since we stand by our products, we created a program called the Efficiency Lab.  This program is to compare your current pneumatic blow-off device with an EXAIR engineered product.  The values we compare are air consumption, noise level and force. We generate a detailed report to send to you for review.  It is a free service that EXAIR provides for U.S. and Canadian companies to know more details about solutions you are currently using in your processes.

Why do we offer this?  Air Compressors demand significant electrical power and compressed air is considered to be a fourth utility within plants and industries.  Many people do not realize the cost and safety concerns when using improper blow-off devices.  As an example, if you look at a single 1/8” open pipe for blowing compressed air, it can cost you over $2,000 a year to operate.  This will add to your overhead and cut profits.  Another reason to consider your blow-off device is that compressed air can be dangerous.  With that same 1/8” open pipe, it can violate OSHA standards for noise exposure and dead-end pressure.  In deciding your “vehicle” for blowing compressed air, cheap is not typically best option.  To put it in other terms, a cheap nozzle is like a cheap old car, it’s cheap because it gets 3 MPG with faulty brakes.

With our Efficiency Lab, a comparison it is quite simple to do.  For starters, you can go to our Product Efficiency Survey on our website to give the conditions for testing.  If you wish for a side by side analysis, you can place your pneumatic device (nozzle, open tube, modified fitting, etc.) in a box and send it to EXAIR.  We will run the tests at the specified conditions or in a range of settings.  We will then return your pneumatic device back to you at our cost with a detailed report of the comparison.  Your information will be confidential, and we will not share it without your permission.  We will also provide a simple ROI – many customers like to use this report to show managers, executives, HSE, etc. on the improvements that EXAIR can provide in cost savings and safety.

How do we do the Efficiency Lab?  We use calibrated equipment and standardized procedures to test for noise levels, flow usage, and force measurements.  We will recommend an EXAIR engineered solution as a replacement to your current device to do the comparison.  With the analytical information, we can also figure the total amount of air savings, return on investment, payback period and safety improvements.

Don’t be fooled; not all blow off devices are the same.  You do not want to sacrifice safety, time, and money with a sub-standard product.  Let EXAIR solve this dilemma with our free service; the Efficiency Lab.  Take advantage of our expertise by using the Efficiency Lab service, we will provide you a detailed report with a comparison analysis to make a great choice.

How to Calculate ROI (Return on Investment)

Published on by Jordan T ShouseLeave a comment

You may have asked…why should I switch over to an engineered compressed air product if my system already works? Or…How can your products be much different?

Manufacturing has always been an advocate for cost savings, where they even have job positions solely focused on cost savings. Return on Investment (ROI) is a metric they look toward to help make good decisions for cost savings.  The term is used to determine the financial benefits associated with the use of more efficient products or processes compared to what you are currently using. This is like looking at your homes heating costs and then changing out to energy efficient windows and better insulation. The upfront cost might be high but the amount of money you will save over time is worth it.

ROI Calculation

How is ROI calculated? It is very simple to calculate out the potential savings of using an EXAIR Intelligent Compressed Air® Product. We have easy to use calculators on our websites Resources where filling in a few blanks will result in an ROI when switching to a EXAIR product! Here they Are, Calculators.

I’ll go ahead and break down the simple ROI calculations for replacing open blow offs with an EXAIR Super Air Nozzle:

  • ¼” Copper Pipe consumes 33 SCFM at 80 psig (denoted below as CP)
  • A Model 1100 ¼” Super Air Nozzle can be used to replace and only uses 14 SCFM at 80 psig (denoted below as EP)

Calculation:

(CP air consumption) * (60 min/hr) * (8 hr/day) * (5 days/week) * (52 weeks/year) = SCF used per year for Copper Pipe  

(33) * (60) * (8) * (5) * (52) = 4,118,400 SCF

(EP air consumption) * (60 min/hr) * (8 hr/day) * (5 days/week) * (52 weeks/year) = SCF used per year for EXAIR Product  

               (14) * (60) * (8) * (5) * (52) = 1,747,200 SCF

Air Savings:

SCF used per year for Copper Pipe – SCF used per year for EXAIR Product = SCF Savings

               4,118,400 SCF – 1,747,200 SCF = 2,371,200 SCF in savings

If you know the facilities cost to generate 1,000 SCF of compressed air you can calculate out how much this will save. If not, you can use $0.25 to generate 1,000 SCF which is the value used by the U.S. Department of Energy to estimate costs.

Yearly Savings:

                (SCF Saved) * (Cost / 1000 SCF) = Yearly Savings

                                (2,371,200 SCF) * ($0.25 / 1000 SCF) = $592.80 annual Savings

With the simple investment of $42 (as of date published) you can calculate out the time it will take to pay off the unit.

Time Until payoff:

                (Yearly Savings) / (5 days/week * 52 weeks/year) = Daily Savings

                                ($592.80/year) / (5 days/week * 52 weeks/year) = $2.28 per day

                (Cost of EXAIR Unit) / (Daily Savings) = Days until product has been paid off

                                ($42) / ($2.28/day) = 17.9 days  

As you can see it doesn’t have to take long for the nozzle to pay for itself, and then continue to contribute toward your bottom line.
