EXAIR Cabinet Cooler Systems are able to cool your electrical panels using only clean, dry compressed air. Other systems such as cooling fans or heat exchangers use ambient air full of dust and humidity. The temperature of ambient air also fluctuates with the seasons and will be very warm in the summer months, which degrades their ability to cool as the temperature rises. One of the myths about compressed air cooling is that humidity from the compressed air source will enter the cabinet. A water/dirt filter separator will prevent condensate from entering the cabinet and since relative humidity is carried away with the hot air exhaust, relative humidity will stabilize to 45%. This video shows how quickly EXAIR’s Cabinet Cooler Systems will have an effect on relative humidity.
Without putting too much thought into it, one might assume that January would not be Cabinet Cooler season. But actually, our friends in the southern hemisphere (Australia, New Zealand, South Africa, Argentina, Chile and Brazil) are experiencing their summer at the very same time that we in the mid-west of the United States have been having some bone-chilling cold weather blow in from Canada. Our New Zealand distributor told me just the other day that they were having 35°C days with water restrictions and everyone is on fire watch because it is so hot and dry right now.
As uncomfortable as that might be for the folks living there, many must continue their production in the un-air conditioned environments. And in doing so, they have to keep their machines up and running to maintain production. But the controls for those machines are not always so cooperative because the CPU is overheating or the inspection camera is giving out because it is too hot.
Where do they turn? EXAIR of course. Once our distributor partner assists the customer with sizing and makes recommendation (sometimes with a little help from us). The customer installs the Cabinet Cooler System and has taken care of their overheating problem within the application once and for all.
The reason why I say “once and for all”, is that the Cabinet Cooler Systems have no moving parts and are virtually maintenance-free. There are no filters to constantly change due to dirty factory environments. And best of all, the Cabinet Cooler can continue to operate in the range of 20 years plus.
When you compare the small cost of a Cabinet Cooler System to that of down time, lost production and the cost to repair burnt out controls, it is truly an easy decision to make.
So, back to our friends in the Southern Hemisphere, where hot and dry is the order of the day, consider having an EXAIR Cabinet Cooler for your application today. Contact us in the International Application Engineering / Sales Department or consult our International Distributor Locator to find the distributor near to you.

With the stretch of hot weather we are having and the rain we got last week my garden at home is absolutely out of control. At least it was until I spent a good two to three hours picking weeds and grass out of the garden. This year we doubled the size of our garden from last year. When I did the garden last year I dug out most of the sod and it really helped cut down on the grass in the garden. When we expanded this year though I was just a little too busy to get the sod dug out and when a good friend tilled the garden for me he churned all the grass into the area. This was fine as he did it for free and I didn’t have to do it; but now I am paying for it. The grass that was in that area is now growing faster than anything else in my garden and was actually choking out all of the onions I had planted.
First I tried to quick fix problem by throwing more dirt over top of the grass to smother it. That worked for about a day. So I did what I had to do, I got in on my hands and knees and picked every little bit of grass out, roots and all. By the end of the next day the onions had all perked up, the tomatoes continued blooming and the zucchini look to be the first vegetable we will enjoy eating.
The fact of the matter is that I didn’t take time to make sure everything was in order before expanding the garden. I didn’t remove the sod, communicate that I preferred the sod out, or mention to my friend that if not removing the sod please chop it up well (a hard thing to state when your friend is doing you such a big favor). Because of that I had to dedicated a good part of my day at home working on a problem I could have prevented. The fact of the matter is a quick fix is just a temporary fix and it is only a matter of time before the real problem reappears and demands your attention.
The same can be said when you band aid an electrical cabinet that is overheating by opening the door and putting a fan in it. That doesn’t solve the problem, it may go away for a short moment, but then it will come back even worse. A fan will provide some temporary cooling but it will also deposit dirt and debris on to the electrical components (all that grime on the fan blades and guard is the same stuff being blown into your cabinet) which causes them to run hotter, short out, or burn. So instead of using a quick fix give us a call and let us help you determine the correct Cabinet Cooler System to cool your cabinet and get the problem solved the right way. The reality of installing a Cabinet Cooler is it takes a short amount of time and effort to install. If compared to other cooling alternatives it may be considered a quick fix – but one that lasts years, is low maintenance, and reliable.
It would appear that the heat is here, as my car has a thermometer which I am pretty sure lied to me on Sunday when it was reading 97°F. I think perhaps it was, but it is getting hotter all across the country and that means we are fielding the calls on electrical cabinets and equipment breaking down due to heat issues. This is all happening just in time for our new promo.
That’s right, order any of the Cabinet Cooler® Systems listed and receive a free A/C Sensor Pen. This pen has saved me from getting shocked many of times around my home. Of course, every time I can’t find my A/C Sensor I have had faith I turned the correct breaker off and as soon as I touch the outlet to change it out I get hit with 110V.
We are here to assist your choice of Cabinet Cooler system and to provide a very fast solution to the downtime you are experiencing. We manufacture Cabinet Cooler systems from 275 Btu/Hr through 5600 Btu/Hr with NEMA 12, 4 and 4X integrity. If you don’t know what Cabinet Cooler System you need, take a look at the form below. It can be found on our site, get the information and call, fax, e-mail or live chat with an Application Engineer to get a quick and accurate response on what amount of cooling your system will need.
Over our thirty years in business we have also seen many companies who only experience a short span of seasonal heat and have found that 2000 Btu/Hr is enough refrigeration to offset summertime heat load, in most cases. Choosing a model with a thermostat control will turn the cooler on and off as needed and minimize compressed air use. Cabinet Cooler systems are in STOCK and ship same day for domestic and Canadian orders received by 3:00 pm EDT. We can get your cabinet cooled FAST and eliminate your heat related problems. Cabinet Cooler systems are shipped ready to install through a standard electrical knockout. There is no waiting for oil to settle back into the compressor motor, no mounting templates required or huge holes to cut into your cabinet. Cabinet Cooler systems have no moving parts to wear, making them rugged and lasting in your hot environment.
Enough already! Enough is enough! I am done with Winter!
I’m sure that I am expressing the sentiments of most the nation. In my sixty some years I cannot remember a winter this severe. I shouldn’t complain though as I have heat and electricity, unlike those who are caught up in the propane shortage.
When you come to think of it, folks in the extreme northern climates deal with this kind of weather as a normal routine. It just proves that we have become so accustomed to a controlled environment, that we have lost our resilience and the ability to cope outside our comfort zone. I am going to take this as a wake up call and stop complaining and go take the dog for a walk.
With cold gripping the country, you would not think that we would be getting calls for our Cabinet Cooler Systems. Quite the contrary as many control panels are in very warm environments such as foundries, bakeries, etc. Also Summer will be coming soon. It would be best to get a Cabinet Cooler System sized up and ready rather than wait for a heat related shutdown.
Our application engineers are available to help you size up your cooling requirements. We have an online form to outline the data we will need to size one up properly. One of our engineers will do the calculations for you and get back to you promptly. Remember last summer when that one panel kept tripping out or alarming every time it got too hot…You may be cold now, but don’t let the heat sneak up on you.
With the Winder Olympics now officially underway I have been trying to figure out just how EXAIR could be a part of the process. Maybe not in the forefront, but what are some applications that are there and have potential for being done by or improved by an EXAIR product.
The first even/ sport I thought of was Hockey. When a skate is sharpened they generally do a dry grinding stone. This can heat up the blade and cause it to become brittle. The best way EXAIR can help is to offer a Cold Gun or a Mini Spot Cooler to apply a cold dry air to the grinding point and keep both the material and the stone cool to offer maximum tool life as well as a finer finish on the blade. (This could probably be used in figure skating too but we’ll stick to hockey for this example.)
The second point was during any of the celebratory events where confetti is dispensed an EXAIR Line Vac or a Super Air Amplifier to help dispense the confetti. We showcase how well this works in one of the Professor Penurious videos.
The final would be the best in my opinion which is to use a Line Vac for a T-Shirt Cannon. Which would help to spread the promotional items in the common areas. We have customers who build awesome t-shirt cannons used at sporting events, I’m just not sure they get the crowd that hyped up within the curling stadium.
So whether you are in the Olympics or simply trying to make some parts for a customer we probably have a product that can help. Feel free to contact us and find out how.
EXAIR Corporation and our products have a robust presence in many overseas places. I should know. I work directly with many of our overseas clients, especially in the Middle East region where just the ambient temperatures climb to 60°C (140°F). If you take that high heat ambient condition and throw in the fact that our customers are working in petrochemical, chemical, cement, glass and plastic industries, the conditions in these manufacturing plants can be torturous not only to personnel but also to the many cabinets which reside in these processes.
I am working presently with a customer in Saudi Arabia who specializes in production of specialty pipe products which combine glass-fiber, resin and sand to produce pipes which can withstand highly corrosive and/or abrasive applications. When you have these kinds of raw materials moving around a production environment, you not only have the issue of high heat conditions, but also the egress of these fine materials into various panels causes many pre-mature failures. As many of us know, housekeeping will usually take a back seat to production. So, the customer is looking for a solution that can keep their panels cool enough to operate and also provide a means to keep a positive pressure to keep these raw materials from migrating inside their panels.
The specific application we are starting with is a panel located very near to where the sand charge is dumped into a mixer to be combined with the resin. The cabinet size is 1200 mm (h) X 1200 mm (W) X 400 mm Depth. The temperatures in this area get up to 60°C and with his internal heat load, his cabinet is getting up to 51°C under present conditions. I asked the customer to fill out a Cabinet Cooler Sizing Guide for me so I could have all the data necessary to run heat load calculations for him. We performed the calculations and came up with 1,170 Btu/hr. that he needed in this case.
After determining the heat load, I evaluated our available HT Cabinet Cooler models and settled on one of the Dual Cabinet Cooler systems to provide them with trouble-free cooling. The specific model was HT4360-240 (NEMA 12, High Temperature, Dual Cabinet Cooler System with 240 VAC thermostat control).
Since this is a technology that the customer was not familiar with prior to our contact, he is exercising prudence and has installed one unit for the time being and is evaluating its performance. This is a fairly new installation. So far, the customer has been satisfied with the performance.
Cabinet Cooler Systems can withstand very demanding applications like the one above. With proper selection and guidance from our experienced Application Engineering staff, you can be assured of similar, good performance in your application as well. Present us with your challenging application today!
