50 Years of Earth Day – Happy Earth Day!

Today marks the 50th anniversary of Earth Day and it will be observed in over 190 countries. For EXAIR, this year marks our 37th year helping compressed air users save compressed air energy and electrical resources. And the 37th year for improving our own efficiencies and processes in order to reduce waste. Because your volunteer opportunities may not be available this year, Earthday.org has gone digital for 2020 and is providing ways to participate via your computer.

EXAIR remains committed to a minimal footprint and continues to focus on manufacturing our products with little impact and doing our part to help protect our planet. We are proud to manufacture efficient products, implement processes and programs throughout our facility to help use our resources wisely and recycle everything we possibly can.

We manufacture and sell Intelligent Compressed Air Products that are specifically designed to reduce the use of compressed air throughout facilities.  On top of that, when you purchase an EXAIR product it will arrive in fully recyclable packaging and, in most cases, is made from a material that will be recyclable should it reach a point it is no longer useful.

Over the past years we continually look for improvement opportunities within our systems and processes. Recently we have…

  • Over the past year, EXAIR recycled 1300 yards of paper and cardboard.
  • Recycled 100% of our cardboard and mixed paper products. Of the waste we place into our trash dumpsters – 80% is recycled and 20% is sent to the landfill.
  • Recycled 100% of the metal scrap from our machining processes. Improvements in these processes has reduced scrap rates, which equates to 5.5 tons of recycled metal.
  • Used our very own Chip Trapper Systems in our manufacturing areas to extend the water-soluble coolant life from 6 weeks per changeover to 6 months per changeover. Keeping our coolant clean allows us to minimize the total amount of wastewater we recycle each year.
  • Further reduced our wastewater for reclamation by another 25% compared to last year.
  • Minimized our own compressed air use by 1 million cubic feet per year
  • Made improvements to the efficiency of our computers and computer servers which require fewer Kilowatt hours (KWH) per day

Another waste reducing factor that has proven to work out well for EXAIR is asking every customer if they accept digital invoices rather than requiring them to be printed and mailed.  We have been able to eliminate over 91% of all printed and mailed invoices. This helps to reduce our resources used as well as the amount of materials that are possibly turned into solid wastes at customer facilities. This also prevents the gas and vehicles necessary to deliver all of these invoices by mail.

Adding to the efforts above, we continue to maintain RoHS compliance on all electronic products, as well as actively track our supply chains to ensure no Conflict Minerals are being sourced and used in our products.

If you have any questions on how we can help your facility reduce their volume of compressed air or why we continue to reduce our wastes and increase our recycling efforts, contact us.

Happy Earth Day from EXAIR!

Webinar by EXAIR: Use This, Not That – Four Common Ways to Save Compressed Air in Your Plant

UThisThat_LIVEOD_600x150

Not much in life is free anymore. So, make sure and take advantage of EXAIR’s upcoming FREE webinar at 2:00 PM ET on 10/17/2019. Not only are we providing it for free, but in this webinar we’ll be discussing how you can save money by reducing your compressed air consumption. Something for free, that will help save you money? Almost unheard of these days!!! Hosted by one of our highly-trained Application Engineers, Jordan Shouse, you’ll learn about four common ways that you can easily save air in your facility.

Compressed air is often referred to as the fourth utility in industry. When used improperly, compressed air is extremely expensive. Homemade devices such as open-ended and drilled pipes, inefficient air nozzles, leaks, etc. all contribute to increased energy costs. In addition to being wasteful, these devices are not safe and compliant with OSHA standards and regulations. By using an Intelligent Compressed Air Product, you’ll be both saving money and creating a safer environment for your operators.

In this webinar, you’ll gain an understanding of the places in your facility that are wasting the most compressed air. We’ll educate you on the various engineered solutions available from EXAIR to help eliminate unnecessary compressed air usage. You’ll gain the knowledge necessary to determine the best solution based on the application, sound level, compressed air usage, and compliance with OSHA safety requirements. You’ll also learn about the various solutions available to help understand and optimize your compressed air system. You can’t begin implementing a plan to reduce air consumption until you fully understand the usage in your own facility and processes. EXAIR’s line of Optimization products are ideal to help you gain a baseline measurement and begin implementing new products and processes that’ll only help add to your bottom line.

After the conclusion of the webinar will be a brief Q&A session where you can ask any questions you have about any of the topics covered. Unable to attend the webinar live? Don’t let that stop you from registering! Afterwards, each registrant will receive a link via e-mail where they’ll be able to access the full webinar at any time. Make sure and take advantage of this opportunity to gain some knowledge about the usage of your compressed air. You’ll be glad you did!

Supply Side Review: Deliquescent Type Dryers

As mentioned in my post last week.  The supply side of compressed air systems within a facility is critical to production.  The quality of air produced by your compressor and sent to the demand side of the system needs to be filtered for both moisture and particulate.  One method to dry the air, that is the topic for this blog, is deliquescent type dryers.

These dryers operate like an adsorbent dryer such as a desiccant medium dryer.  The main variance is that the drying medium (desiccant) actually undergoes a phase change from solids to liquids.  Because of this the material is used up and cannot be returned to its original state for reuse.   The liquids formed by the desiccant dissolving in the removed water vapor are then filtered out of the air stream before it is passed on to the demand side of the air system.

There are many compounds that are used to absorb the moisture in the wet compressed air.  A few options are potassium, calcium, or sodium salts and many that contain a urea base.  The desiccant compound must be maintained at a minimum level for the dryer to contain enough media to successfully dry the air.

These dryers are generally a single tank system that is fed with compressed air from a side port near the bottom of the tank.  The air then travels up past drip trays where the desiccant and water mixture fall and ultimately ends up in the bottom of the tank.  The air then goes through a material bed that must be kept at a given level in order to correctly absorb the moisture in the air.  The dry air is then pushed out the top of the tank.

As the desiccant material absorbs the liquid from the compressed air flowing through the tank it falls onto the drip trays and then into the bottom of the tank where it is drained out of the system.  This process can be seen in the image below.

The dew point that this style dryer is able to achieve is dependent on several variables:

  • Compressed air temperature
  • Compressed air pressure / velocity
  • Size and configuration of the tank
  • Compression of the absorption media
  • Type of absorption media and age of media

These dryers are simplistic in their design because there are no moving parts as well as easy to install and carry a low startup cost.

Some disadvantages include:

  • Dewpoint range 20°F – 30°F (Again this is according to the media used.)
  • Dissolved absorption material can pose a disposal issue as it may not be able to be simply put down a drain
  • Replacement of the absorption material

Even with disadvantages the ability to supply the demand side of a compressed air system for a production facility is key to maintaining successful operations.  If you would like to discuss any type of compressed air dryer, please contact us.

Happy Earth Day 2019!

Today marks the 49th annual Earth Day and it will be observed in over 193 countries.  For EXAIR, this year marks our 36th year helping compressed air users save compressed air energy and electrical resources.

It is also another year that we continue to focus on manufacturing our products with minimal impact and doing our part to help protect our planet. We are proud to manufacture efficient products, implement processes and programs throughout our facility to help use our resources wisely and recycle everything we possibly can. 

First and foremost, we manufacture and sell Intelligent Compressed Air Products that are specifically designed to reduce the use of compressed air throughout facilities.  On top of that, when you purchase an EXAIR product it will arrive in fully recyclable packaging and, in most cases, is made from a material that will be recyclable should it reach a point it is no longer useful.

Over the past years we continually look for improvement opportunities within our systems and processes. Recently we have made improvements to the efficiency of our computers and computer servers which require fewer Kilowatt hours (KWH) per day. We have further reduced our wastewater for reclamation by another 17%, and minimized our own compressed air use by 1 million cubic feet.

We use our very own Chip Trapper Systems in our manufacturing areas to extend the water soluble coolant life from 6 weeks per changeover to 6 months per changeover. Keeping our coolant clean allows us to minimize the total amount of wastewater we recycle each year. 

EXAIR recycles 100% of the metal scrap from our machining processes, which equates to 6.5 tons. Our cardboard and mixed paper products are also recycled 100%. Of the waste we place into our trash dumpsters – 80% is recycled and 20% is sent to the landfill.     

In total over the past year, EXAIR recycled 36.6 tons of paper and cardboard which equates to 80% of the solid waste we produce is recycled.  We focus on more ways to improve this percentage every year.

Another waste reducing factor that has proven to work out well for EXAIR is asking every customer if they accept digital invoices rather than requiring them to be printed and mailed.   Thanks to our wonderful customers we have been able to eliminate 91% of all printed and mailed invoices which helps to reduce our resources used as well as the amount of materials that are possibly turned into solid wastes at their facilities. This also prevents the gas and vehicles necessary to deliver all of these invoices by mail. 

On top of all the efforts above, we also continue to maintain RoHS compliance on all electronic products, as well as actively track our supply chains to ensure no Conflict Minerals are being sourced from the Democratic Republic of Congo.

If you have any questions on how we can help your facility reduce their volume of compressed air or why we continue to reduce our wastes and increase our recycling efforts, contact us.

Happy Earth Day from EXAIR!
