EXAIR Cabinet Cooler System Meets High Demands Of Sea Duty

I joined the Navy, right after high school, to get out of Ohio, see the world, and never come back. “My recruiter said” (if you are considering military service, those can be famous last words, just so you know) that I would be a good candidate for Nuclear Power School, so I took the test. As a math & science nerd scholar, I qualified for admission easily.  About halfway through Nuke School, I volunteered for submarines.  My decision was based in no small part on the sea stories of our instructors, the strong reputation of better food, and my deep appreciation for the movie “Operation Petticoat.”

Upon graduation, I was assigned to a new construction Trident submarine.  I did not see the world…I saw the Electric Boat shipyard in Groton, Connecticut, and Naval Submarine Base King’s Bay, Georgia.  Hilarity occasionally ensued, but never in the context of that movie I so adored.  I moved back to Ohio (on purpose) soon after my enlistment was up.  The food WAS good…I can unreservedly vouch for that.

In the new construction environment of the shipyard, I became quite familiar, and developed a deep respect for, the high level of attention paid to the materials and workmanship that a seagoing vessel demanded…not to mention, one with a nuclear reactor on board.  Reliability and durability are obviously key factors.

I had the pleasure recently of assisting an electrical contractor who was looking for a cooling solution for a new Variable Frequency Drive enclosure installation on a cement barge.  The ship’s engineer (a Navy veteran himself) had told the contractor that his priorities were reliability, durability, and dust exclusion.  He couldn’t have made a better case for an EXAIR Cabinet Cooling System.

Based on the specified heat load of the VFD, the size of the enclosure, and its location, a Model 4380 Thermostat Controlled NEMA 12 Cabinet Cooler System, rated at 5,600 Btu/hr, was specified.  This equipment is internal to the ship; had it been exposed to the elements, a NEMA 4X system would have been presented.

Up to 2,800 Btu/hr cooling capacity with a single Cabinet Cooler System (left) or as much as 5,600 Btu/hr with a Dual system (right.)

EXAIR Cabinet Cooler Systems have no moving parts to wear, no electric motor to burn out, and no heat transfer surfaces (like a refrigerant-based unit’s fins & tubes) to foul.  Once it’s properly installed on a sealed enclosure, the internal components never see anything but cold, clean air.

If you have a need to protect an electrical enclosure in aggressive environment, give me a call.  With a wide range of Cabinet Cooler Systems to meet a variety of needs, we’ve got the one you’re looking for, in stock and ready to ship.

EXAIR Atomizing Spray Nozzles Make It Nice & Foggy In Greenhouses

Fog. Nobody likes driving in it. It’s downright perilous to sailing vessels on the open water, but especially those near the shore, or other watercraft. Flights get delayed or cancelled, stranding travelers in airport terminals far from home, and keeping many from pressing matters that necessitated the speed of an airline flight in the first place.  Oh, and it’s ALWAYS where the bad guy is hiding in the movies.  You can tell by the ominous low-string music that starts playing right before things get real nefarious.

You know who LIKES fog, though?  Greenhouse operators.  Their plants get plenty of water to sustain their growth from the well-irrigated soil, but the leaves & petals can wither and get discolored if the humidity isn’t kept at a high level.

The same is true for the parts of a greenhouse that folks don’t see when they’re selecting the annuals to plant on the next nice spring weekend (which we should be coming up on quite soon here!) – like the seed germination chambers.  I had the pleasure of helping a greenhouse operator recently, who needed to replace some old, and malfunctioning, nozzles in one of their germination chambers.  They were interested in the extremely fine mist that our Atomizing Spray Nozzles produce.  After some experimentation with a couple of different flow rates & patterns, they determined that the Model AW1020SS (Wide Angle Round Pattern, Internal Mix) Atomizing Spray Nozzles provided optimal results.

The fine, atomized mist (left) produced by the EXAIR AW1020SS (right) optimizes the seed germination in this chamber.

As the fogging systems in their other chambers start to fail, they’ve been replacing them with the AW1020SS’.  We shipped them two earlier this week.

With (90) distinct models to choose from, we’ve got the solution to your liquid spraying application.

EXAIR Atomizing Spray Nozzles offer an incredibly wide range of flow rates, patterns, and adjustability to suit most any application that requires a fine liquid mist.  If you’d like to find out more, give me a call.

What Makes Things Easier Than An EXAIR Static Eliminator? Another EXAIR Static Eliminator!

A contract manufacturer, servicing the medical and biotechnology markets, is a long time user of our Ion Air Guns. They’ve had great success with them in keeping their products free from static & dust for years. These are mainly small, hand-held parts, so, when they need to get them clean and static-free during assembly and packaging, EXAIR’s Ion Air Gun is ideal, because it, too, is small and hand-held.

A new process, though, involves the operator needing both hands for assembly. This would mean picking up the Ion Air Gun, blowing off the part, putting it down, and then using both hands to complete the operation. They thought there had to be a better way. And they were right!

The Model 8910 Instant Static Elimination Station offers hands-free control of ionized air flow – a foot pedal turns an Ion Air Jet (whose performance is identical to the Ion Air Gun) on and off with…well, the press of a foot. The Magnetic Base and Stay Set Hose make it easy to install, and even easier to position.

Hand held convenience of the Ion Air Gun (easy) or no-hands convenience of the Ion Air Jet Station (easier.) Your call.

Hand held convenience of the Ion Air Gun (easy) or no-hands convenience of the Ion Air Jet Station (easier.) Your call.

For an even more automated approach, they are considering an EFC Electronic Flow Control. They’re ready to go, right out of the box…the photoelectric sensor will open and close a solenoid valve (installed in the compressed air supply line) based on the setting of the programmable timer unit. With a simple wave of the part in front of the sensor, the operator could activate a preset blow of a few seconds, which would be easy to determine, even easier to set, and…easiest of all…reliably repeat all day long. They’re going to try out the foot pedal first, and that’s just fine by me.  Perhaps there’s such as thing as “too easy,” but man, I hope not.

Even if you’re already using EXAIR products to make things easy, you can call me to see how much easier it might get.

How To Solve A Problem with Compressed Air

In my (almost) six years as an EXAIR Application Engineer, I’ve learned a great many things about the capabilities of our products.  The way we do business sure does make it easy:

  • We readily share application information, as a team.  If you ask me a question, you’re asking all of us.  It does neither of us any good if I tell you something MIGHT work if one of my team knows it WON’T – or if someone knows what else DOES work.  If we can offer a solution, we will.
  • We’ll test your product, free of charge.  This is a popular way of finding out which Line Vac is best for conveying a particular product, for example.
  • If you’re considering a quiet, safe, and efficient EXAIR product as an upgrade, we’ll test your current product in our award winning Efficiency Lab, so you can compare accurate performance data and analyze the expected benefits…which can be dramatic.  Try us on that.

  • We’ll let YOU test our product, risk-free.  All catalog products come with a 30 Day Unconditional Guarantee.  We invite you to put it through its paces for up to a month.  If it’s not working out, we’ll arrange return for full credit.
  • We’ll do the math.  But first, a disclaimer: strictly comparing the force or flow of an engineered product to an open-end blow off won’t always tell the tale.  Our Intelligent Compressed Air Products are creating a laminar flow which won’t generate as high of a force/thrust as open-end blowing (which is turbulent by nature,) but is MUCH more conducive to efficiency and noise reduction, as well as similar (if not improved) performance.  But back to the math: if you know the metrics you need to meet for spot cooling (like a Vortex Tube, Adjustable Spot Cooler, Cold Gun, etc.) or for liquid spraying (the liquid flow rate and/or pattern size & shape from an Atomizing Spray Nozzle, for instance,) or the heat load that a Cabinet Cooler System can handle, we’ll do the calculations and specify the appropriate product.

Regardless of the application, if it can be solved with compressed air, it’s very likely that we have a great solution.  Call me to find out how we can help.

More Power May Not Be The Solution

I can’t tell you how much it pains me to write this after last week’s blog. But, if we’re being honest here, every Tim “The Tool Man” Taylor (“More Power!”) does indeed need an Al Borland (“I don’t think so, Tim.”) As evidence of this, I had an opportunity to provide reasoned advice to a caller on the tech support line this week:

They had just purchased a Model 110224 24″ Aluminum Super Air Knife Kit. The flow it produced wasn’t powerful enough for their needs, so they installed extra shims from the Shim Set (which comes with the Kit) – increasing the shim gap to 0.009″ (which can produce a great deal more air flow and force)…more power, right?

Super Air Knife Kits include a Shim Set, Filter Separator, and Pressure Regulator.

Super Air Knife Kits include a Shim Set, Filter Separator, and Pressure Regulator.

Unfortunately, not. The Super Air Knife makes a hard hitting curtain of air when supplied properly…but it’s going to need a 1/2″ pipe (ID of ~5/8″) to carry enough compressed air flow to make that happen. Turns out, they were using 1/4″ tubing, which wasn’t even getting enough compressed air flow to the unit with just the 0.002″ shim installed. Putting in the extra shims actually made that worse. Once they ran a 3/4″ hose to the Air Knife (and took out those extra shims,) they were actually able to regulate the air supply back to about 60psig, which provided a strong enough air flow to solve the application.

This table comes directly from the Installation & Operation Instructions for the Super Air Knife.

Sometimes, though, compressed air product applications DO come down to a need for more power.  Next week, I’ll tell you about a caller who said he needed “the biggest and most powerful” Safety Air Gun we had – and unlike the last time I wrote a blog about that – he was RIGHT.
