Overheating Cabinets Are Bad. Cabinet Cooler Systems on Promotion Are Good!

Published on by Brian FarnoLeave a comment

In southwest Ohio we are currently experiencing 88°F. And we have begun to see increased numbers of inquiries for Cabinet Cooler Systems to keep control cabinets cool. This comes with the territory of approaching summer here in the northern hemisphere, and elsewhere it is due to new machines going into areas of a facility where it is constantly hot and dirty. It seems like the perfect time to offer up some free stuff with our Cabinet Cooler Promotion.

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.   Without it of course, I find myself guessing I turned the correct breaker off and, as soon as I touch the outlet I am working on I get hit with 110V. This sensor is helpful to locate the presence of voltage and avoid getting shocked.

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 as well as Hazardous Location. If you don’t know what Cabinet Cooler System you need, take a look at our new Cabinet Cooler Calculator or 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.

Sizing Guide

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.

EXAIR’s New Cabinet Cooler® System Calculator

Published on by Jordan T ShouseLeave a comment

For the longest time we have been using this form on EXAIR.com to get the information we needed to manually calculate the internal and external heat loads and ultimately make a recommendation on which Cabinet Cooler System would be best for that application! Typically it would take thirty minuets to an hour to get a email back from a application Engineer!

While the manual Cabinet Cooler Sizing Guide worked great (and we will still reply within 24 hours), we have been racking our heads over here to better that process and get you a solution faster than ever! Now you type in your information and you have a recommendation and a link to that product on the website where you can learn more or place an order! So you can go from form to order in less than 5 Minuets!!!! Check it Out HERE!!

By providing certain information like size of the enclosure, NEMA rating needed, and environmental conditions, this new calculator will sort through our large selection of ready-to-ship Cabinet Cooler® Systems and provide instant feedback on the best model number for any applicable electrical enclosure.  Taking the guess work out of the equation, EXAIR’s Calculator ensures the customer that they can be confident in selecting the correct product for their unique specifications. You can even Print the form for your records!

Cabinet Cooler® System Calculator – EXAIR’s Latest Do-It-Yourself Tool!

Published on by Brian FarnoLeave a comment

At EXAIR we are constantly moving, changing, growing, and building products and tools to help anyone that comes into contact with us or our products. Evidence of this includes our continued launches of new product and tools that you can see in our Press Releases. Our newest tool provides a do-it-yourself solution to determine which Cabinet Cooler System model number your electrical or control panel will need. This easiest way to reach this new tool is to follow our websites Resource’s button to the Calculator Library. We have made the selection process easier and faster with this new calculator.

Historically, the Cabinet Cooler sizing guide was the fastest way to receive a recommendation – But now, the calculator provides a do-it-yourself solution with instant feedback!

While we have always offered the ability to fill out a Cabinet Cooler Sizing Guide (above) and email, call, chat or fax the information to us. With the right amount of information provided, an e-mail will provide you an answer within 24 hours. With a phone call or online chat, we can get you an answer in 5-10 minutes. But now you can receive instant feedback as to which Cabinet Cooler System is needed to combat an overheating cabinet by using the Cabinet Cooler Calculator. We have poured our knowledge and experience from over the years into the tool to best fit to our standards of correctly calculating and compensating for diverse environments and demands of electrical panels.

With some basic information on the panel, environment, and compressed air available, the calculator will calculate the internal heat load, external heat load, compensate for non-optimal compressed air temperature or pressure, and solar heat load(where applicable) then show the exact model number needed to reach the desired temperature for the panel. You can then immediately learn more about that specific model or order that model online. Of course you can also reach out to anyone here at EXAIR and receive answers to additional questions and or place the order with an actual person.

If you want to discuss your overheating panels or if you have some questions on why we are asking for certain variables on the Cabinet Cooler Calculator, feel free to contact us.

Radiant Heat- Where Does It Come From

Published on by Brian FarnoLeave a comment
Even in extremely aggressive environments, EXAIR Cabinet Cooler Systems provide reliable heat protection for your sensitive electronics and controls.

The three types of heat transfer have been discussed here and there on this blog before. One of the most common heat transfer methods that I deal with on a day to day basis is radiant heat transfer. Also known as thermal radiation, the process is actually the exchange of energy by photons. The main difference separating radiant heat from convection and conduction is that radiation does not require there to be a medium to permit propagation of the heat. Any item which contains thermal energy, meaning it is above absolute zero and less than 1,000 Kelvin, will have this thermal energy. This thermal energy is radiated to other items causing a transfer of heat energy to those objects that results in an equilibrium between the items. The equilibrium does not stop the transfer of photons however.

The most common occurrence that most of us get to experience for radiant heat is heat from the Sun. As the sun shines it is emitting heat. On a hot day, generally the sun is a little closer to your geographic location and you feel hot because the sun is emitting more heat onto your surface than what is being emitted by your internal temperature, so your core temp will increase. On a cold day, when the sun is further away, while it is still shining you feel cold because the sun is not in fact transferring as much energy to the surface of your body than what you are internally generating. The same kind of radiant heat transfer can be from a campfire, open kiln, maybe even a hot steel slab coming out of a blast furnace.

The model 1126SSW 1″ Flat Stainless Steel Super Air Nozzle w/ Swivel Fitting cools a flame sensor within an industrial furnace.

Understanding where a radiant heat source is being generated can help tremendously when looking at cooling an electrical enclosure or even trying to keep a part or sensor cool. Radiant heat is one of the few times a heat shield or shade structure can help to eliminate a portion of the heat load being introduced. Other methods to combat the heat load would be determined with the application at hand. For cooling enclosures that are absorbing a solar heat load, we would look at an EXAIR Cabinet Cooler System and the factors that help to appropriately size the cooler. If this is a single component or part, we would evaluate one of the many other EXAIR Engineered Solutions to determine the best fit for the application. To do either of these, all it takes is a simple chat, email, or call to an Application Engineer.
