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!
EXAIR’s complete line of Cabinet Cooler systems include 120V AC, 240V AC and 24V DC thermostat voltage, continuous operation, type 316 stainless steel and high temperature models – all of which are selectable with the new calculator. Find this new tool on the website EXAIR.com, in the Knowledge Base Calculators, along with many other resources, such as the CAD Library and Application Database, which also help customers choose a perfect solution. Cabinet Cooler systems start at $534. https://www.exair.com/knowledgebase/calculator-library/cabinet-cooler-system-calculator.html
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.
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.
In Ohio, there’s a long-running joke that we actually have 12 total seasons throughout the year. It’s not uncommon to enjoy a day in early-March with sunshine and highs in the low 70s. It’s also not uncommon to have temperatures dip into the single digits along with a late bout of snow. That point at which we begin to experience warm temperatures is known around these parts as “Spring of Deception” or “False Spring”. This is followed abruptly by “Third Winter”. Needless to say we’re all sick of the rain, snow, cold, and ready to get outside and enjoy some warm weather!
With springupon us, that means summer is right around the corner. While this is an exciting event for most of us, your maintenance manager may beg to differ. Increased temperatures lead to heat related problems in your electrical panels. With summer coming along before you know it, the time is now to get a solution in place before it becomes an issue.
EXAIR’sCabinet Cooler Systems were designed specifically to rectify these issues within your facility. Utilizing Vortex Tube technology, the Cabinet Cooler produces cold air from an ordinary supply of compressed air. This cold air keeps the enclosure free of debris and moisture and is easily installed in minutes through a standard electrical knockout. Here is a short video that shows just how simple it really is. The Cabinet Cooler Systems are available with Nema 12 (IP54) ratings and are also available in Aluminum, 303 Stainless Steel, and 316 Stainless Steel construction for Nema 4/4X (IP66) rated enclosures. For systems that are not able to be mounted on top of the cabinet, we also have Side Mount Kits available in Aluminum, 303 Stainless, and 316 Stainless. This year, EXAIR also introduced a new line of Hazardous Location Cabinet Coolers for use in classified areas.
These systems are available with cooling capacities of anywhere from 275-5,600 Btu/hr. To make things much easier for you, we offer a Cabinet Cooler Sizing Guide that will allow us to recommend the most suitable model for your cabinet. With a few quick measurements, we’ll be able to determine the exact heat load that we’ll need to dissipate and offer you a quick and easy solution. If you experienced heat related issues on electrical panels last year, contact an Application Engineer today and we’ll see to it that this summer your cabinets remain cool!
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.
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.
