6 Primary Benefits of Cabinet Coolers (Vortex Tube Enclosure Coolers)

First off, I want to dispel any notion that there might be something that’s NOT great about EXAIR Cabinet Cooler Systems.  Are there other methods to provide effective cooling to an electrical panel?  Of course there are, and frankly, if one particular method was clearly superior in any & every situation, the makers of that one would have put all the others out of business by now.  But for now, let’s consider:

1. Simplicity: Cabinet Cooler Systems need compressed air to work.  That’s it.  Supply them with clean, moisture free air, and they’ll run darn near indefinitely, maintenance free. What could be easier?

2. Control:  Continuous Operation systems have their place (more on that in a minute,) but in most cases, Thermostat Control is preferred, for a couple of reasons:

  • Most electrical and electronic components have a rated maximum operating temperature of 104°F (40°C).  Maintaining the air temperature at a reasonable level less than that is all you need…any lower, and you’re just wasting energy, no matter what method of cooling you use.  Our Thermostats are preset at 95°F (35°C) to ensure heat protection, while limiting operating costs.
  • There is such as thing as “too cold.” Particularly sensitive instrumentation & controls may exhibit varied behavior at different temperatures.
  • Our bimetallic probe-type thermostats are ideal for controlling air temperature.  They have much faster response time than other mechanical styles, meaning the system won’t keep running once it’s cool enough, and it starts running as soon as it starts getting too hot.  They’re also easy to reset, if the preset of 95°F (35°C) is not suitable for particular specific needs.
  • If constant monitoring, or frequent changes in control temperature are desired, the ETC Electronic Temperature Control offers these benefits, via a quick response thermocouple and pushbutton operation.

3. Environmental concerns: No matter where a panel is located in your plant, and what it might be exposed to, EXAIR Cabinet Cooler Systems will keep the environment out of that panel:

  • NEMA 12 Cabinet Cooler Systems are oil tight, dust tight, and rated for indoor duty.
  • NEMA 4 systems provide the same protection as NEMA 12, and are additionally splash resistant, and are rated for indoor/outdoor duty.
  • NEMA 4x systems offer NEMA 4 protection, and are made of stainless steel for corrosion resistance.
  • HazLoc Cabinet Coolers are UL Classified & CE Compliant.

    HazLoc Cabinet Cooler Systems also maintain NEMA 4 or 4X integrity, and are for use with classified enclosure purge & pressurization systems in hazardous locations:

    • Class I Div 1, Groups A, B, C and D
    • Class II Div 1, Grouds E, F and G
    • Class III

4. Dependable protection: In most cases, the less moving parts something has, the more reliable it is.  With NO moving parts, EXAIR Cabinet Cooler Systems absolutely prove this out:

  • Unlike refrigerant-based systems, there are no filters to clean, no coils to foul or corrode, and no electric motors to burn out.
  • No potential contaminants from outside air ever enter the enclosure…all the cold air comes from your compressed air supply, through an Automatic Drain Filter Separator fitted with a 5 micron particulate element and a centrifugal separator for moisture removal.

5. Selection:  Cooling capacities range from 275 Btu/hr to 5,600 Btu/hr, and they’re all in stock, ready for immediate shipment.

6. Special considerations:  “Customized” usually means high prices and long lead times. Not so for a number of EXAIR Cabinet Cooler System options:

  • This NEMA 4 Dual Cabinet Cooler System protects a critical equipment panel on a hot roll steel line.

    High Temperature systems are available from stock, for installation in areas where the ambient temperature can exceed 125°F (52°C,) all the way up to 200°F (93°C.)

  • Continuous Operation Systems aren’t the only way to constantly keep environmental contaminants out…Non-Hazardous Purge (NHP) systems combine the efficiency of Thermostat Control by always passing a small amount of air flow, to provide a slight positive pressure, even when the temperature is lower than the Thermostat set point.  This way, the Cabinet Cooler System only operates to maintain appropriate cooling, but the panel is still protected all the time.
  • When additional protection from harsh and corrosive environments is needed, or when specified by strict facility requirements (I’m looking at you, Food, Pharma, and Nuclear Plants,) our NEMA 4X Cabinet Cooler Systems can be provided in Type 316 Stainless Steel construction, from stock.

6.5 Simplicity, part 2:  Not only are they simple to operate…

  • They install, in minutes, through a standard knockout in the top of your enclosure.

    Side Mount Kits maintain NEMA 4/4X Splash Resistance.
  • If there’s no room on top, or if it’s just more practical, you can put them on the side of the panel using a Side Mount Kit.
  • Don’t know which one to pick, or need help determining your heat load?  Then use our Cabinet Cooler System Sizing Guide.  There’s one in the catalog that you can fill out and fax or email to us, or you can find it on our website under the “Features” tab on any Cabinet Cooler product page…just fill in the blanks and click “Submit.”  Or, you can always simply call in the data to an Application Engineer.  We can calculate your heat load in just a minute or so, and we do it over the phone all the time.

If you’d like to find out more about heat protection for your electrical or electronic panels, give me a call.

Labor Day 2017

What does Labor Day mean to you? Summer’s last hurrah? An extra day to sleep in, extend a weekend trip, or (ugh) tackle a home improvement project? Something else entirely, or all of the above? I neither expect, nor want, this to change any plans or mindset, but as U.S. federal holidays go, I find the history and meaning of Labor Day to be fascinating.

Maybe not as fascinating as Mister Spock preparing to drop the bass, but still pretty fascinating.

1777 – The first unions were organized in the United States by printers, carpenters and shoemakers, seeking better wages and shorter hours.

1825 – The United Tailoresses of New York, the first all-women’s union, is formed in New York City.

1827 – The Mechanics Union of Trade Associations forms in Philadelphia to call for a standardized 10-hour workday.

1840 – President Martin Van Buren establishes a 10-hour workday for federal workers.

1868 – The first federal 8-hour labor law is passed, but only applies to a small group of federal workers.

1885-1886 – Several municipalities around the United States declare Labor Day ordinances – a day of rest to recognize the social and economic achievements of American workers.

1887 – Oregon passes the first state-wide Labor Day observance law.  Colorado, Massachusetts, New Jersey, and New York follow suit this same year.

1891 – Labor Day is established as a national holiday by the Congress of the United States.

I don’t have the space (or the will) to get in to a detailed discourse on the highs (and lows) of the achievements (and setbacks) of the American working class through the 20th Century.  If I did, I’d choose to focus on the positive.  Almost everyone I know who’s in the American work force – family, friends, neighbors, and especially my co-workers at EXAIR – enjoys a safe work environment, fair wages & benefits, and opportunities unavailable anywhere else in the world.  So, Monday, I’ll take the day off that our forebears fought and earned for us.

If you’d like to talk about a compressed air product application, give me a call.  On Tuesday.

Never Think Your Idea Will Not Be Heard

The above title proved very true in a work experience of my father’s. After working in the mill for several years, he drew up a new piece of process equipment which would eventually turn in to something that they put in place on the production line.   This was all done from his idea that he was able to place on a scrap piece of paper as a drawing.   While he wasn’t the decision maker in the process, he was the person who saw what kind of impact this device could have and knew the people he had to get the information to.

That brings me to the topic of this blog, don’t ever think an idea is too small to warrant a reward.  This can ring true throughout any type of application, including compressed air.  There have been instances where a maintenance worker, or even a new operator, have called in to speak to me here asking what can they do to lower the noise in the work area when they are using the hand held blow gun the company supplies.   After talking to them about what they are trying to achieve with the blow gun and how much air they are currently using, we generally find that they can save a good amount of compressed air, lower the noise level, and become OSHA compliant, all by changing this one simple tool.   Once they have all the benefits that their company will see from implementing our engineered solution, they can then propose this to the decision makers.

For the most part, companies will at the very least entertain ideas like this.  When you back that idea up with some relevant data on how much money the company will save, or the fact that is will make the work environment safer and more enjoyable, then you will more than likely get a little more attention.  The main point is to ensure that you are getting that information to the correct person and that you have the correct information.   That is one of the many reasons that EXAIR has a full team of Application Engineers who can help you identify how much air you might be using, what products will fit the need, and what kind of benefits your company will see.   On top of all the information that we have available for free, we even offer the chance to get compensation for sharing application data with us.

EXAIR Efficiency Lab
EXAIR’s Efficiency Lab will test your product for force, flow, and noise.

That’s right, we will compensate you for sharing your cost savings, sound level reductions or application improvements, with us.  This is all possible through our Case Study program.  All you have to do to find out more is contact any Application Engineer.  We simply need some photographs of the application and some quantitative data for the benefits you have gained.  Don’t know what your current device is using, take advantage of our EXAIR Efficiency Lab, that will give us a good amount of information we need to then, help you solve a problem as well as produce a Case Study.

If you would like to discuss your compressed air systems or how we can help you, please contact us.
