Helping Within Our Community

Throughout my tenure here at EXAIR I have seen the company give to many different organizations and to the team members here.   Recently we implemented a program where employees are allowed to choose a charity of their choice to go and volunteer for a day each year.  This year for my volunteer day a group of seven members from EXAIR went to help a non-profit organization that focuses on helping students and teachers in 16 local counties.

The organization, Crayons to Computers is a free store for teachers in these counties that surround Cincinnati.  The store is stocked with donations from corporate and private entities and staffed by volunteers.  Their inventory can be anywhere from classroom supplies, books, decorations, technology equipment, even stocked book bags to give to students.  The store is the largest of its kind here in the United States and has been serving the Cincinnati area for 20 years. Their belief is that a teacher should not have to spend money out of their pocket to supply students in need with school supplies and to ensure that schools in need have access to supplies that aren’t always easily available.

They have a sales floor where the teachers shop and then a large warehouse where the donations are all sorted and stocked for easy pull to the sales floor when needed.  This is where our team spent the day.  We did jobs like sorting books by reading level, organizing / packaging chair mats, unloading trucks, and finally, consolidating over 30,000 boxes of 24 count crayons so that their valuable warehouse space was being used more efficiently.  These crayons were all donated by financial institutions here locally that had challenged each other to see who could donate more.  It still isn’t the amount of crayons that they will supply to teachers within this school year, but it helps tremendously.

By volunteering our time we were also able to give 10 teachers who’s school would not normally qualify for shopping at Crayons To Computers the ability to go and shop for a day.  This was an added bonus that we were made aware of after the fact.  This is yet another way that Crayons to Computers gives to our community.

One of the best takeaways I have from this year is that I got to give back to an organization that my amazing wife would shop at when she was teaching students in need.  It was organized by someone here on our team that had no knowledge of my personal connection. We ended up getting more done than they had ever hoped to get out of 7 volunteers.  This was all made possible by a company that doesn’t just focus on making excellent products and providing top notch customer service.  EXAIR is also focusing on making sure our team members interests are embraced by letting them choose how to give their time and the companies time to a cause they believe will give back to our local community.

If you would like to inquire about donations or how you could help Crayons to Computers, please check out their site directly.

Utility Rebates for Energy Savings

Since the establishment of EXAIR in 1983, customer satisfaction has always been the cornerstone of our business model.   This may seem like a common practice, but here at EXAIR, we like to go the extra mile.  We have over a 99.9% on-time delivery with thousands of products in stock.  We offer free expert technical help from our Application Engineers, as well as within EXAIR Blog writings and application search library.  We have an Efficiency Lab to report on comparison results with safety and compressed air saving.  We also offer a 30-day unconditional guarantee on our cataloged products for you to try.   So, what more can EXAIR do for you?

Free testing. Verifiable data. EXAIR Efficiency Lab.

Compressors use large amounts of electricity to produce compressed air and are considered the fourth utility in most manufacturing plants.  EXAIR manufactures engineered products that can save compressed air and increase energy savings.  With that, EXAIR was able to partner with Energy Star.  “Energy Star is a government-backed symbol for energy efficiency helping to save money and to protect the environment through energy-efficient products and practices.” This commitment by EXAIR for reducing energy, increase safety for workers, and protecting the environment for future generations are effective ways to sustain a business value.

When large amounts of energy can be saved, electricity producing companies take notice.  Electrical suppliers started a rebate program for using engineered nozzles in their facility.  Similar to other energy-saving rebates, like LED light bulbs and high-efficiency furnaces, EXAIR engineered nozzles now fall into that same category.  If your electrical provider supports this program, the total cost to purchase and implement the EXAIR Super Air Nozzles are greatly reduced.  Even if a rebate program has not yet been implemented in your area, the idea of saving energy makes it very practical and environmentally sound.

The NC Clean Energy Technology Center created a website to consolidate all the electrical companies that offer rebates for efficient products and programs.  The website is www.dsireusa.org.  “DSIRE is the most comprehensive source of information on incentives and policies that support renewable and energy efficiency in the United States.”  EXAIR engineered products fall into this category, so if a rebate can be applied to our products, it will be located on that site.

Back to the question above, what more can EXAIR do for you?  We all live busy lives at work and at home.  It may be difficult to find the proper programs from your local power companies.  Let EXAIR do most of the legwork for you.  Per your request, we can help find the proper forms for rebates when switching to EXAIR engineered nozzles.  With a rebate program, it makes it very cost effective to upgrade your pneumatic system to an energy efficient system.

Being backed by Energy Star, EPA, and rebate programs, together, we can save energy, improve the environment, and reduce compressed air usage.  If you would like to discuss how EXAIR can work for you, you can contact an EXAIR Application Engineer to get the most out of that extra mile.

Standards, Compliance, And You. And EXAIR.

I’m pretty impressed with the number of safety features my car has. Aside from the literal lifesaving functions like seat belts and air bags, it’s got anti-lock brakes…if you’ve ever had to counter-steer out of a skid on an icy road, you will appreciate the value of this for sure.  Those are just some of the ones I’m keenly aware of – the Federal Motor Vehicle Safety Standards comprise dozens of regulations in three categories: crash avoidance, crashworthiness, and post-crash survivability.  None of these prevent me from operating my vehicle at an unsafe rate of speed…an expensive reality that an Ohio State Highway Patrolman dutifully reminded me of last Sunday afternoon.

Likewise, there are many regulations to ensure safety and prevent hazards of all kinds in industry, administered by a host of agencies that are either subordinates of, or accountable to, the federal government.  When you manufacture products that are used with high energy sources (compressed air or high voltage electricity,) a strong commitment to safety is not negotiable.  So, at EXAIR, we commit considerable resources towards the best engineering and manufacturing practices to make our products as safe as possible.  That includes compliance with a number of standards and certifications:

The Occupational Safety and Health Administration (OSHA) is an agency of the U.S. Department of Labor.  Their mission is to “assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.”  They are a regulatory body in the truest sense, in that they don’t offer certification or approval of products, processes, etc.; they publish guidelines and standards for manufacturers and users to comply with.  OSHA Standard 1910.242(b), for instance, limits the downstream pressure of a compressed air operated device used for cleaning purposes to 30psi. Now, you can regulate the supply pressure to meet this, but that also limits the effectiveness of the air flow generated.  EXAIR Intelligent Compressed Air Products are all designed and manufactured to be in compliance with this standard, at any supply pressure.  Take, for example, our Super Air Nozzles:

Because none of our products can be dead-ended, there’s always a relief path preventing the downstream pressure from exceeding that level.

OSHA also has Standard 1910.95(a), that sets limits for maximum allowable noise exposure.  All EXAIR Intelligent Compressed Air Products, with the exception of some our largest and most power Super Air Nozzles (which aren’t normally used in areas that don’t already require hearing protection anyway) meet the 8-hour exposure limits of this standard.

Hearing loss is the best known, but not the only, ill effect of harmful noise exposure. It can also cause physical and psychological stress, impair concentration, and contribute to workplace accidents or injuries.

CE marking indicates conformity with health, safety, and environmental protection standards for products sold withing the European Economic Area.  Unlike OSHA standards, responsibility for CE marking falls solely with the seller of the product – a CE marked product has been tested and certified to have been made in such a way to meet safety & quality benchmarks specified for that type of product.  All EXAIR products that are defined under applicable directives have been tested according to these standards, and carry the CE mark.

The Restriction of Hazardous Substances Directive, or RoHS, is another standard borne from the European Union, and is geared towards public & workplace safety by restricting the use of hazardous materials in the manufacture of electronic & electrical equipment.  Since its inception in 2006, similar standards have been vigorously adopted around the globe.  Electrical portions of EXAIR’s Static Eliminators, EFC Electronic Flow Controls, ETC Electronic Temperature Controls, Digital Flowmeters, Solenoid Valves, and Thermostats all comply with the RoHS Directive.

Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act doesn’t address a concern for product users, but rather a particularly troubling human rights issue – Conflict Minerals.  For almost two decades, trade in tin, tantalum, tungsten and gold in the Democratic Republic of the Congo (DRC) has been used by some very bad people to finance violent campaigns against their neighbors.  EXAIR thoroughly and systematically documents our supply chain compliance with this act.  We are proudly committed to our support for this effort to the world a better place for everyone…especially those in desperate circumstances beyond their control.

EXAIR Intelligent Compressed Air Products have been successfully implemented into a variety of uses where application- or industry-specific standards are in force.  We’re happy to work with you to determine if our products meet those standards…or can be made to meet them.  If you’ve got such an application, give me a call.

Memorial Day 2018

Across the United States, we are gearing up for our traditional observance of Memorial Day, on Monday. A good many of us will be fortunate to enjoy an extra day off…EXAIR employees included; we’re closed Monday, May 28, for the holiday.

In the temperate climate of the mid-Atlantic region where I live, there’s going to be a LOT of landscaping and gardening going on. Those with swimming pools will be starting the chemical balancing game that, with any luck, they’ll win before Labor Day. As for me, my rest & relaxation game will be strong for most of the weekend.

Monday, though, my family and I will join many others from our community at our township’s Memorial Day parade. My son plays in the local High School Marching Band, and they will be leading it out with a grand display of brass and winds and drums and color guard and patriotic musical selections. Volunteers from a vintage military aviation museum at our local airport will conduct a “fly-over” that never disappoints. Members of other civic-minded groups will likewise join the parade. And we’ll all take time to remember those who gave their lives in service to our nation.

Whatever your plans are for this weekend, I join the rest of the EXAIR team in wishing for you a perfect blend of rest, relaxation, productivity…and remembrance.

Real Heroes Of Science: James Clerk Maxwell

People who watch way too much TV (like me) will certainly remember the “Real Men of Genius” commercials.  Here’s one of my personal favorites:

Local radio stations all over the country made parodies of these, as did sketch comics.  While trying to come up with something for my weekly blog, I saw that today was the anniversary of the passing of 19th century physicist James Clerk Maxwell.  So, if you’ll try to keep the background music from the video above playing in your head while you read this, let’s see if I can pay proper tribute:

James Clerk Maxwell…even though Albert Einstein is famous for the Special Theory of Relativity, he credited YOU for laying the groundwork.  You not only theorized the relationship between electricity, magnetism, and light, but you also proved it mathematically…so Albert didn’t have to.  He said your work was “the most profound and the most fruitful that physics has experienced since the time of Newton.”

Singer: Albert Einstein pretty much called you an “Einstein” the way we call geniuses “Einsteins.”

Professor Maxwell…you devoted your life to learning.  About EVERYTHING.  As if solving Einstein’s problem with the Theory of Relativity (40 years before he knew he had a problem with it) wasn’t enough, you decided to find out what the rings of Saturn were made of.  Over 100 years before we could send the Voyager spacecraft to find out for sure.  And you were right.

Then you discovered how to take color photographs by experimenting with light filters.

Singer: Not only did you tell us what Saturn’s rings were made of, we have color photographs of them thanks to you….

James Clerk Maxwell…your theory that a “friendly little demon” could somehow separate gases into hot and cold flows, while unproven in your lifetime, did actually come to fruition by the development of the Vortex Tube.  Which does just that.

Singer: That’s right, I just drew a straight line from Maxwell’s Demon to EXAIR’s Vortex Tube & Spot Cooling Products!

So here’s to you, James Clerk Maxwell…may we continue to recognize your brilliance, and be inspired by your drive to push forward in scientific developments.

Singer (building to final crescendo): James Clerk Maxwell, a Real Hero Of Sci-i-i-i-i-ence!

If you’d like to hear the musical parts of this actually get sung, or if you’d like to find out more about Vortex Tube products and their uses (it might be best to stick with that second part actually,) give me a call.

Intelligent Compressed Air: Deliquescent Dryers – What are They and How do They Work?

EXAIR has written blogs about the different types of dryers that are used to remove liquid from compressed air systems. In this blog, I will be discussing the deliquescent dryer. This dryer falls under the desiccant dryer category, and unlike the regenerative cousins, it is the least commonly used type of dryer. The regenerative desiccant dryers use a medium that will adsorb the water vapor, and the deliquescent dryers use a hygroscopic material that will absorb the water vapor. This salt-like medium has a strong affinity for water, and it comes in a tablet or briquette form. Placed inside a single unit pressure vessel, the “wet” compressed air passes through the bed to become dry. The size of the pressure vessel is determined by the compressed air usage which allows for the proper amount of contact time with the hygroscopic bed. Generally, the dew point will be between 20 to 50 deg. F (11 – 28 deg. C) less than the compressed air inlet temperature. Unlike most dryers, the dew point after deliquescent dryers will vary with the inlet air temperatures.

Vessel Design

The design of vessel is very important for the function of a deliquescent dryer. A grate is required to hold the medium off the bottom. The compressed air will flow from the bottom, up through the bed, and out from the top. The predetermined space between the bed and the bottom of the vessel is used for the liquid that is generated. When “wet” compressed air passes through the bed, the hygroscopic material will absorb the water and change the tablets from a solid into a liquid. Deliquescent dryers got the name from the definition of the verb, “deliquesce” which is “becomes liquid by absorbing moisture from the air”. Once the material is turned into a liquid, it cannot be regenerated. The liquid must be discarded periodically from the vessel and new solid material must be added. With the single tower design, the deliquescent dryers are relatively inexpensive.

Some advantages in using the deliquescent dryers are that they do not require any electricity or have any moving parts. So, they can be used in remote locations, rugged areas, or hazardous locations. They are commonly used to reduce the dew point in compressed air, natural gas, landfill gas and biogas systems. Without the ability for regeneration, no additional compressed air will be lost or used. In comparing the power requirement to other compressed air dryers, the deliquescent dryers have the lowest power requirement at 0.2Kw/100 cfm of air. (This energy rating is only due to the additional power required for the air compressor to overcome the pressure drop in the dryer).

Some disadvantages in using the deliquescent dryers is that the hygroscopic material degrades. The deliquesced liquid does have to be drained and disposed, and new material does have to be added. Even though they do not have any moving parts, they still require periodic maintenance. The deliquescent material can be corrosive. So, after-filters are required to capture any liquid or dust material that may carry over and damage downstream piping and pneumatic components. Also, the variation in the dew point suppression can limit locations and areas where it can be used.

If you have questions about getting the most from your compressed air system, or would like to talk about any EXAIR Intelligent Compressed Air® Products, you can contact an Application Engineer at EXAIR. We would be happy to hear from you.
