The Flexibility of Vortex Tubes

Vortex Tubes have the ability to solve many heat related problems within industry by creating a focused stream of cold air. Generally referred to as a spot cooling product, we often get the question “what can you do with them?” 

Beyond some of the application I will highlight here, you may also register in our Knowledge Base where you can browse through 800+ applications within the Application Database for our products. The easiest way to look through only Vortex Tube applications  is to enter “Vortex Tube” in the bottom, blank field of the application search box.

You will see that the Vortex Tubes are used thoughout industry. In my first example our customer forms tubes from steel strip. The strip is washed in a 140F solution then move over a series of rollers. The initial roller was building up heat transferred from the steel strip and had cracked due to longterm exposure to heat. With a Vortex Tube they  have cooled the 4″ dia. x 2″ wide roller to prevent heat transfer from strip steel.

Another customer, who manufactures weed control chemicals, is filling 5 mililiter vials with a warm chemical gel. The gel is at 40C when poured into the vial and sets up at 38C. Their Vortex Tube was used to blow into the vial and create a skin on the chemical gel to seal the gel in the vials.

We have also sold a Vortex Tube to a  manufacturer of dietary supplements who uses gelatin in their process. They convey the gelatin into a bulk hopper with a slide gate on the bottom. On the other side of the slide gate is a steam heating process which melts the gelatin for processing. The heat was building up in the slide gate and melting the gelatin at the bottom of the bulk hopper, causing more maintenance upon the slide gate than desired. They used the cold air from a Vortex Tube through a flexible line to wrap the slide gate and cool it from the outside to prevent heat buildup.  

A heat activated adhesive was giving a veneer manufacturer problems beacause they ran the adhesive through a 4″ pipe to deliver it from the source to the veneer line. Part of this pipe ran up high in the rafters and was picking up too much environmental heat during the simmer and causing the adhesiv eto thicken up and preventing it from being applied properly. This customer used a Vortex Tube to push air through a 5″ pipe x 10′ long around the 4″ section of pipe. This has prevented the adhesive from picking up the heat and causing problems.

Vortex Tubes are also the fundamental product used in our Cold Guns, which are preset, non-adjustable cooling products built for maximum Btu/Hr. They make up our Adjustable Spot Coolers which can acheive very cold temperatures at low volume or high Btu/Hr values. And of course, they are used to manufcature our Cabinet Cooler systems used to cool electronic enclosures.

Vortex Tubes are ideal for hot, dirty, hard to reach or maintain areas. They have no moving parts and require no maintenance beyond changing out a compressed air filter element once or twice a year. If you are experiencing a heat related problem in your production, consider a Vortex Tube.

Your Day Job Versus Your Passion

An ancient sage once said “make your hobby your job and you will never have to work another day in your life“. You say, that would be nice but some of us have to earn a living to support our families. True, what we like to do and what we can earn a living doing may be conflicting, at least at first. Try taking an interest in the product that you are producing. Learn who your companies competitors are; how does your company stack up against them, who your customers are and how are they using your product, how are others in the industry doing what you are doing. A simple web search will yield you all the information you need. At first this may seem laborious and irrelevant to developing your job satisfaction, but you will grow into it. You may be surprised at what you may find on the way that  piques your interest.

Very early in my career I worked for a company that made sockets and wrenches. I made a casual acquaintance with one of the forge press operators.  He was one of the more senior employees and with his seniority could have had the pick of any job opening in the plant. The press room is hot, noisy, and dirty. Not where I would want to work. I asked him why he stayed at that job.  He told me because it was his passion.

He said that when he first started it was drudgery and he could not wait to find a better job. It was at a county fair that he got his revelation. He was watching a farrier make horseshoes when he came to realize forging was a process as ancient as man. He began reading about the subject. The more he read the more questions he had which led to more reading. He eventually became a self-taught metallurgist. When he sees the red-hot metal give way to the forge dies, he envisions how the molecular structure is changing and why various metals react differently.

That still did not answer my question as to why stayed at his job and not become an engineer. He looked me square in the eye and said ” would you rather design a race car or drive one. I prefer driving myself”

Part 4 of 6: Turn it off.

Well trusty blog readers, we are 2/3 of the way to an optimized compressed air system. We have already learned how to measure our compressed air operation usage. This was done using an EXAIR Digital Flow Meter. The next step was to find any leaks in the system using the EXAIR Ultrasonic Leak Detector, and then fix them permanently. This is going to allow you to see just the cost of your current blow offs. Then we implemented any and all applicable EXAIR Intelligent Compressed Air Products. By implementing the EXAIR Products we were not only able to save compressed air but also lower the noise level of the surrounding area. This also aided with our OSHA compliance. The next step is to turn of the applications when they are not needed. This proposes the question.

If your product is not a continuous run that requires your compressed air operation to be on all the time then take a look into the EXAIR Electronic Flow Control, EFC for short. This device will allow you to control how long your compressed air operation is turned on or off with each trigger of the sensor. A very good example of this is depicted below with computer monitors. You can see when the screen was not in the air stream the air did not need to be on. This is a prime case for an EFC to be installed. If you wish to know more detailed information on this example such as how much the customer was able to save click on the picture for the link.

The best part of this step in our Six Steps to Compressed Air Optimization is, the objective is clear. When your compressed air doesn’t need to be on turn it off and save. For more information on the EFC or our Six Steps to Compressed Air Optimization feel free to contact us.

Until next week.

Stay Tuned

Have you ever found yourself with big news that you’d love to share, but the timing just isn’t right yet?

I had four really good blog topics lined up for this week, or so I thought. Four more first-and-only announcements from EXAIR. Because of a little detail here or there, none of them turned out to be ready today.

I wanted to tell you about a completely new family of products coming soon from EXAIR. Engineering is putting the finishing touches on them right now. But that’s about all I can say about them right now. Stay tuned for more information.

On another front, I planned to announce another round of compliance news for EXAIR products. Turns out we are waiting for a couple of labels, so we’ll have to wait a bit longer. Probably no more than a week. Once again, stay tuned.

And we have a big announcement coming on the conservation and sustainability front. And, as usual, EXAIR sets the pace. Once again, we have to finalize a couple of details including a label. It shouldn’t be much longer. Stay tuned.

And finally, EXAIR once again has product award news. It’ll be posted soon, we promise. We are waiting for some information from the organization handling the awards. We should have what we need by next week. Stay tuned.

It seems like all of these projects are coming to fruition at the same time, and we’ve got a little bit of a logjam near the finish line. But we’re not complaining. There are many problems worse than finalizing too many new things at once.

Some companies might go a year or two and never manage to finish one of these kinds of projects, let alone four at once.

I’d hate to be part of one of those slow moving companies.

Stay tuned for more. There is plenty more in the pipeline. It’s part of what makes EXAIR so special.
