EXAIR’s Cabinet Coolers Meet Specific Environmental Needs

I wrote recently about a “textbook” application for EXAIR Cabinet Cooler Systems…overheating control cabinets on a factory floor, solved quickly & easily with stock product, off the shelf, installed in minutes.

“Well, la-di-da, Russ,” some may say, “You sure knocked that whiffleball out of the park, didn’t you? What about those of us with more complex requirements than a plain Jane electric box on a typical production floor?”

To them, I would say:

1. Yes we did, and thank you for noticing!
And
2. Read on.

EXAIR manufactures, and stocks, a number of special Cabinet Cooler Systems to meet most any need:

Food and pharmaceutical processing areas often call for specific materials of construction. Something that doesn’t corrode, something that isn’t susceptible to surface wear or pitting in a washdown environment…something like Type 316 Stainless Steel. For these cases, we also offer our complete line of NEMA 4X Cabinet Cooler Systems in optional 316SS construction, from 275 Btu/hr (69 Kcal/hr) to 5,600 Btu/hr (1,411 Kcal/hr.) And they’re all in stock.

Of course, other harsh environments, like this outdoor installation at a wastewater treatment plant, also require the highly corrosion resistant properties of 316SS.

EXAIR Cabinet Cooler Systems work best on a sealed enclosure, but sometimes it’s not feasible to completely seal an enclosure – there may be a cable bundle coming through a common penetration, or perhaps the door isn’t fitted with a gasket.  In cases where such equipment still needs to be protected from dust, fumes, or other environmental contaminants, you could always use a Continuous Operation Cabinet Cooler System.  But, if you want to control operating costs with Thermostat Control, our Non-Hazardous Purge option provides a continuous positive flow, even when the internal temperature is below the Thermostat setpoint, to prevent these contaminants from entering.  These are all in stock as well.

Non-Hazardous Purge option is available for any EXAIR Cabinet Cooler System.

When we calculate heat load, we use your Sizing Guide data to determine both internal heat load (generated by the components in the enclosure) and external heat load (generated by the ambient temperature in the area.)  Regardless of the internal heat load, enclosures in extremely hot locations need protection too.  When the ambient temperature will exceed 125°F, a High Temperature Cabinet Cooler System is specified…performance is identical, but they’re outfitted to withstand the higher temperatures for durability and long lasting operation.  This option is offered for all of our Cabinet Cooler Systems 1,000 Btu/hr and higher, and they are also all in stock.

This Dual Cabinet Cooler System protects a critical equipment panel on a hot roll steel line.

No matter the challenges of your facility’s environment, we can help.  Again…all of the above options are in stock, ready for immediate shipment.  What could be better?

Well, actually, we ARE giving away free stuff with Cabinet Cooler System orders through the end of July 2018:

This applies to our standard Cabinet Cooler Systems, as well as those with options for various environmental considerations detailed above.

So…don’t overheat your electronics from the inside, or out, wherever they’re located.  If you’d like to find out more, give me a call.

EXAIR’s Cabinet Coolers Provide Heat Protection 24/7

I had the pleasure of speaking with the Maintenance Manager at a manufacturing plant for a global automotive supplier earlier this week. They have a whole factory floor full of machinery that operates from PLC controls. The space is not climate controlled, and the temperature broke 100°F the day before. This triggered some high temperature warnings on several control panels, but that was the worst thing that happened…luckily.

It should go without saying that the automotive industry is a big deal in the United States…maybe even a bigger deal here in the Middle Atlantic region, and a HUGE deal for those of us within a few hour’s drive of Detroit, Michigan…the home of the Big Three.  Disruptions in their supply chains can affect not only the final production of automobiles, but also other suppliers, vendors, and service providers in separate “links” of that chain.  So, if my caller has a breakdown and can’t ship parts, many other suppliers’ lines may be slowed or stopped, because if Detroit can’t make cars without one supplier’s parts right now, they won’t need the others’ parts right now either.  That means reliability is paramount.

Even in extremely aggressive environments, an EXAIR Cabinet Cooler System is a durable, reliable heat protection solution for your sensitive electronics and controls.

This is a “textbook” situation for EXAIR Cabinet Cooler Systems.  They’re installed in minutes, have no moving parts, and require only a supply of compressed air for operation.  If that air is clean & dry, they’ll operate darn near indefinitely, maintenance free.  Thermostat Control turns them off & on as needed.  I’ve talked to more than a few users who were (pleasantly) surprised when a Cabinet Cooler System activated on the first hot day in the spring, after not seeing it come on at all, after that last hot day near the end of the previous summer.

Back to the situation at hand – the Maintenance Manager had gathered Sizing Guide data for a couple of enclosures.  You can submit it through our website, or email it in, but it only takes a minute; we do it over the phone all the time.  So I did, and quoted the appropriate Cabinet Cooler Systems, which were ordered soon after.  They were installed the next day, with a promise of more to come.

EXAIR Cabinet Cooler Systems are widely recognized as an ideal solution for electrical & electronic panel heat protection.

As if quick, easy, and reliable heat protection for sensitive and critical electronics isn’t enough, we’re sweetening the pot this summer:  order any EXAIR CAbinet Cooler System by July 31, 2018, and we will include a FREE AC Sensor, suitable for testing breakers, receptacles, switches, fuses, junction boxes, power cords – if it’s got (or should) have AC voltage going through it, the AC Sensor will light up and sound off (or not) to let you know for sure.

If you have electrical or electronic equipment enclosures that need heat protection, EXAIR has the solution.  Call me.

EXAIR’s Cabinet Cooler System is Durable and Reliable

Any realtor will tell you that the three most important factors in selecting a property are location, location, and location. This simply means that houses with similar features – number of bedrooms, yard size, structure, garage (or not,) basement or not,) etc. – can be found in a lot of very different neighborhoods. Whether you want to live somewhere that’s convenient to the highway, close to (or not so close to) work, near your favorite activities, etc., odds are you can find a house that meets your material needs & wants within those geographical confines. Hence, location is your #1 consideration. And your #2 and your #3 as well…my lovely bride is a real estate professional, so I have this on good authority. And, so you know, #4 is price, and #5 is condition.

Electrical and electronics controls professionals will tell you that three of the most important things to protect their equipment from are heat, moisture, and dust. If you’re looking for a durable, reliable, and low cost method for that, we’ve got the solution: the EXAIR Cabinet Cooler System. Selection of the right system comes down to determining your heat load, and…the reason for today’s blog…the LOCATION in which it will be installed.

Let’s say it’s a control panel for one of the machines on a factory production line…indoors & dry.  Our NEMA 12 Cabinet Cooler Systems provide protection against dust and oil from entering the enclosure.

NEMA 12 Cabinet Cooler Systems are oil tight, dust tight, and rated for indoor duty. They can also be installed to the wall of an enclosure (instead of the top) with a Side Mount Kit.

If the enclosure is outdoors, or indoors but subject to water spray (like in a wash-down area,) our NEMA 4 Cabinet Cooler Systems are oil tight, dust tight, AND splash resistant.  They ensure the inside of the enclosure stays dry through the use of a low pressure relief valve that seals when the cooler is not operating, maintaining NEMA 4 integrity at all times.

EXAIR NEMA Cabinet Cooler Systems provide additional protection to keep the enclosure dry inside.

Our NEMA 4X Cabinet Cooler Systems are made of stainless steel, and are commonly specified for food service area installations, and in corrosive environments.  They’re also oil tight, dust tight, and splash resistant.  These are also available in Type 316 Stainless Steel construction, for especially harsh conditions, or when this is otherwise specified due to the nature of the installation, such as critical food grade or pharmaceutical areas.

EXAIR NEMA 4X Cabinet Cooler Systems are made of corrosion resistant stainless steel for corrosive environments, and are also available with Side Mount Kits.

Regardless of the NEMA rating called for by the location, all EXAIR Cabinet Cooler Systems are available with a Non-Hazardous Purge option, which provides a slight positive pressure through a low (1 SCFM) air flow when internal temperature is below the thermostat setpoint and the solenoid valve is closed.  This provides constant and reliable protection, even if the enclosure is not perfectly sealed, even in especially dirty or dusty environments.

All EXAIR Cabinet Cooler Systems are available with Non Hazardous Purge for constant, reliable protection from environmental contaminants.

High Temperature Cabinet Cooler Systems are also available when ambient temperatures can exceed 125F.  These are popular in foundries, glass production facilities, and even non-air conditioned spaces in particularly warm climates.

High Temperature Cabinet Cooler Systems provide reliable heat protection in areas where ambient temperatures reach 125-200F (52-93C)

If you’ve got sensitive, mission-critical electrical or electronic enclosures that need reliable heat protection, EXAIR has the solution you’re looking for.  If you know the required cooling capacity for your enclosure, you can select the right system directly from our website.  If you’d like help in calculating your heat load, you can use our Cabinet Cooler System Sizing Guide…just fill in the blanks and click “submit” – your request will be forwarded to an Application Engineer for immediate attention.  Or, if you’d rather, just give me a call.  We calculate heat loads over the phone all the time; it only takes a minute.

How To Make Compressed Air Get Cold…A Couple Of Different Ways

The Vortex Tube makes cold air for the same reason that a can of compressed air gets cold when I clean my computer keyboard, right?

That’s a common question, and since they both start with compress air and end up with cold(er) air, it’s not an unreasonable assumption.  But the answer is no; they’re not the same.   Both are curious physical phenomena, though:

Cans of compressed air get cold while they’re discharging because of a thermodynamic principle known as the adiabatic effect.  When you pressurize a gas by compressing it into a container, you’re putting all those molecules into a smaller volume of space…and you’re adding potential energy by the compression.  Then, when you release that gas back to atmospheric pressure, that energy has to go somewhere…so it’s given off in the form of heat – from the air inside the can, as the pressure inside the can decreases.  Now, the air that’s not under as much pressure as it was when you pushed the button on top of the can is going to start coming out of the can pretty soon.  I mean, there’s only so much air in there, right?  So, since it’s given off that energy immediately upon the drop in pressure, when it comes out of the can, it’s at a lower temperature than it was before you started spraying it out.

Vortex Tubes, on the other hand, generate a flow of cold air by a completely different phenomenon of physics called, maybe not so curiously, the Vortex Tube principle:

You can get a lot more cold air – and a much lower temperature – from a Vortex Tube than you can from a can of compressed air.

If you need a reliable and dependable flow of cold air, look no further than EXAIR’s comprehensive line of Vortex Tubes and Spot Cooling Equipment.  We’ve got 24 models of Vortex Tubes to choose from, as well as “out of the box” solutions for cooling applications like the Adjustable Spot Cooler, Mini CoolerCold Gun Aircoolant Systems. and, to protect your sensitive electrical and electronic enclosures from heat, Cabinet Cooler Systems.  If you’d like to find out more, give me a call.

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.

How Versatile Are EXAIR Compressed Air Products?

I wish I could quantify that, but we keep finding more and more applications for them:

Vortex Tubes are used all the time for cooling applications, down to MINUS 40 degrees (Fahrenheit OR Celsius…that’s the point where they’re both the same; no math required.) They also produce a HOT air flow, which we usually call “exhaust,” but some users actually use IT for heating, and call the COLD flow the “exhaust.”

The EXAIR Vortex Tube. Cold air from one end; hot air from the other. Fully adjustable. You can use either...it's fine with us; whatever you need.
The EXAIR Vortex Tube. Cold air from one end; hot air from the other.  You can use either…it’s fine with us; whatever you need.

Our E-Vac Vacuum Generators are popular for “pick-and-place” jobs…hook one up to a Vacuum Cup and you can move parts around all day long. One time, though, I helped a

customer who needed to “pick-and-place” individual small pieces of woven fabric, a lot like a coffee filter. Even our smallest E-Vac, supplied from a Pressure Regulator cranked all the way down, was too much…it would still pick up most of the stack. We found they could use a Model 120020 3/4″ Super Air Amplifier just fine…the Pressure Regulator was still cranked all the way down, and it picked them up one at a time.

No matter what you need to pick-and-place, we've got you covered.

Our Super Air Knives are perfect for blow off, drying, and cooling applications…whether you’re trying to rid your product of dirt/debris, water, or heat, a laminar curtain of adjustable air flow is a “textbook” solution. But I recently had the pleasure of helping a customer who needed to KEEP SOMETHING IN PLACE and called to ask about an Air Knife. They had small cups running single-file down a conveyor belt, with an overhead brush roller pushing down on them at one point so they could be treated on one side. Without something holding them in place, the tooling would simply push them off the side of the conveyor. It required frequent adjustment because they run different sized cups…and they almost always lost some cups when they switched to a different size, while “dialing in” the brush tension. By installing a Model 110036 36″ Aluminum Super Air Knife in place of the brush, they can hold any size cup in place with the downward air flow “curtain.” No more lost product when they don’t get the brush adjustment just right!

Continuous, even, fully adjustable curtain of air...EXAIR Super Air Knives come in lengths from 3 inches to 9 feet.
