When Efficiency And Practicality Collide

Even if you’re a casual reader of our blogs, you already know that EXAIR Application Engineers LOVE to preach efficiency in the use of compressed air…it’s our “bread and butter;” the very nature of our business. This year, we’re celebrating thirty-five years of leading the way in the development of efficient, safe, and quiet compressed air products. Our track record of success as a solutions provider across a diverse range of industrial and commercial applications is well documented in our blogs, as well as Knowledge Base and Case Study Libraries.  We devote considerable resources (engineering, research & development, product testing, etc.) to making certain that EXAIR Intelligent Compressed Air Products cost less to operate, and perform better, than whatever you’re using right now.

Strange as it may seem, though, sometimes our products are EXTREMELY popular in cases where they INCREASE a facility’s consumption of compressed air…by replacing something that DOESN’T use compressed air at all:

*I’ve written before about how our Large Maximum Cold Temperature Vortex Tubes have replaced liquid nitrogen rigs in freeze sealing operations.  Now, a Vortex Tube directs a portion of its air supply to (usually) unusable hot exhaust, in order to generate the usable flow of cold air.  When compared to the costs of liquid nitrogen and the resources involved to get it where it needs to be, though, the cost of the compressed air needed to operate the Vortex Tube is indeed the practical solution.

A 1/4 ton of refrigeration from a product that fits in the palm of your hand, and all you need is a supply or compressed air!

*Line Vacs are probably THE prime example of the value of using compressed air where it wasn’t used before…replacing a “bucket and ladder” operation:

Straight from our Catalog, a perfect example of using valuable compressed air to save even more valuable resources.

*Then there are the situations that just come down to time.  In large spaces, our Super Blast Safety Air Guns can be used to “sweep” the floor in a fraction of the time it takes an operator with a push broom.

Super Blast Safety Air Gun makes short work of large area cleanup.

To make a long story just a little bit longer…if you’re using compressed air, you can use it better with EXAIR’s engineered compressed air products.  And there are plenty of practical applications where you’re not using compressed air right now too.  If you’d like to find out more about either one, give me a call.

Cool Job, Cool Products

I’ve got a pretty cool job. I’ve written about this before…in fact, as recently as last week, in a piece about workplace safety, and how EXAIR is all over it, all the way. Brian Farno also blogged the other day about how EXAIR recognizes, appreciates, and celebrates achievement. Like usual, actually.

So yeah; this is a pretty cool job. And, just to put that into perspective, my first “grown up” job set the bar pretty high: upon completion of Naval Nuclear Power School, I was assigned to the initial manning crew of a new construction Trident submarine. When I got there in the spring of 1987, “tha thirty-five boat,” as the future USS Pennsylvania (SSBN-735) was known, was ON the pier (not NEXT to it) and we boarded through hull cuts in Engine Room Lower Level & the Torpedo Room. For two years, we worked with shipyard personnel to install, test, & certify all ship’s systems, and then took her out in the summer of 1989 for a rigorous series of sea trials. I wish there were words capable of conveying the extent of “job satisfaction” we felt when we submerged for the first time, and the whole ocean stayed outside the boat.

I was reminded of this the other day when I saw a news account of the bow section of a submarine being transported via barge from the shipyard that fabricated this section, to the shipyard that’s assembling the boat. Here’s a video clip of one such transit, from about a year ago:

I’ve written before about how compressed air is (and isn’t) used on board a submarine at sea. Compressed air is also used, for some pretty neat stuff, in their construction & service. And EXAIR Compressed Air Products are in the mix:

*Sometimes during work on a piping system, it’s not possible to isolate a particular section with valves, so a freeze seal is applied: a collar fits around the outside of the pipe, and very cold fluid is circulated through the collar. This freezes the liquid inside the pipe, forming a “plug,” which allows you to work on the piping downstream, just the same as if you had shut a valve there. One method of doing this is with liquid nitrogen…you take a big tank of the stuff to your work site, implement all the safety precautions you need to handle pressurized liquid at -321°F (spoiler alert: it’s complicated,) make up your connections, hope they don’t leak, and activate the system. Depending on the length of the job and the size of the tank, you may need to change it out…which, again, is complicated.  And yes, I’ve done it.

It's a real shame to foul this view with a block & tackle to lower a pressurized nitrogen tank down.

Or, like several shipyards are doing currently, you can install an EXAIR Maximum Cold Temperature Vortex Tube to the collar, run a compressed air line to it, and you can supply cold air as low as -40°F, which will freeze a plug in that pipe for as long as you keep your air compressor running.

Vortex Tube
EXAIR Vortex Tubes produce cold air, on demand, with no moving parts.

*Another application has to do not with the equipment, but the people working on it. Welding is a hot job – there’s really no way around it – and welding in tight spaces can present real issues for the folks involved. Fans and blowers can provide a good amount of ventilation, but they also take up some room, which there may not be any to spare.

Enter EXAIR Air Amplifiers – they’re compact, lightweight, and use a small amount of compressed air to blow a high flow of cooling air, right where it’s needed.

EXAIR Air Amplifiers use a small amount of compressed air to create a tremendous amount of air flow.

These are just a couple of examples of how a large industry – shipbuilding – is using EXAIR products to capitalize on efficiency in a challenging environment. Regardless of your situation, if you’d like to learn if EXAIR can help out, give us a call.
