Cabinet Cooler Replaces Open Tube Compressed Air Cooling For Electrical Panel at Brewery

Much of the news cycle these past few weeks has covered this massive “heat dome” that’s elected to hang out over much of the Central and Midwestern US. As a result, temperatures for much of the US (and elsewhere in the world) have reached or exceeded record highs far more often than we’d expect from a typical summer. To add insult to injury, an El Niño weather pattern emerged in July that’s exacerbated the problem due to warming ocean temperatures in the Pacific.

While this heat has led to a wonderful pool year at the Daniel household, it’s not exactly an ideal situation for control panels in an industrial facility. As temperatures rise inside your plant, this can begin to cause issues with your electrical panels. Rather than letting the heat buildup inside, EXAIR offers our Cabinet Coolers to address this heat before problems arise.

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.

I recently worked with a customer in the brewing industry that experienced a myriad of issues with their electrical panels last summer. Their maintenance manager came up with the idea to place a 5mm ID tube (operating at 4 BAR, or 58 psi) to keep the air purged with compressed air. While certainly wasteful, it did work for them for a period of time as temperatures began to creep up in their plant. However, as soon as temperatures began to rise to around 90°F inside, the warm compressed air was no longer effective. As high heat alarms began to sound throughout the shop floor, they began looking for an alternative solution.

They landed on the EXAIR website and filled out a Cabinet Cooler Sizing Guide. We were able to determine that our Model 4830 2000 Btu/hr system was more than enough to keep things at a safe temperature. Not only were we able to reduce their air consumption, but rather than blowing hot compressed air into the panel we were now delivering air 50°F cooler than the supplied compressed air. The vent that was permitting the compressed air to exhaust was sealed off, which helps keep the panel clean during months where cooling is not needed.

A 5mm ID tube operating at 4 BAR (58 psi) will consume 40.08 SCFM of compressed air. Our Model 4830 comes in at 30 SCFM at a pressure of 100 psi for rated operation. A 33% reduction in compressed air usage wasn’t necessarily their goal, but a welcomed result nonetheless. The Cabinet Cooler was installed in minutes and immediately solved their overheating issues. With several more panels in the facility using the same ineffective method of cooling, they plan to outfit all their panels with an EXAIR Cabinet Cooler.

Don’t wait until you have a line down to start fixing the issues with your electrical cabinets. Contact an EXAIR Application Engineer today. We’ll help ensure you’re able to operate year-round WITHOUT heat-related shutdowns.

Like a Donkey Between Two Haystacks


Having been born and raised in the northern climates, for me 80 degrees is hot. So when temperatures soar into the 90’s I really struggle to cope. Bad news is that according to NOAA, we are in store for above average temperatures for the remainder of the summer!

High temperatures are not only uncomfortable for we humanoids, electronics suffer as well. The demand for panel cooling is extensive and my company, EXAIR, produces Cabinet Cooler systems. There in lies my dilemma. I would like to wish for the heat to go away but then that would be wishing ill for my company. I’m like a donkey trying to decide between two hay stacks.

So, I will stay in my air conditioned cubical and calculate cooling requirements for customers. I would welcome the opportunity to assist you with your panel cooling requirements. Give me a call at 1-800-903-9247

The End of the World As We Know It

How many times do you watch the news or read the newspaper and wonder if REM was right back in 1987?

We have the various natural disasters like floods, earthquakes, typhoons, hurricanes and tsunamis around the globe.  Check.

And we have the man-made versions as well.

The spring and summer of 2010 has been spent by millions watching a webcam over a mile below the surface of the Gulf of Mexico with growing outrage.  Maybe the latest cap just placed on the well is working – or maybe it’s making things worse and the reservoir could simply collapse and leak even more oil uncontrolled into the Gulf.  The “top kill” solution was attempted but didn’t work.  The “static kill” solution could begin soon – or maybe not because there seems to be a hurricane on the way.  The relief wells could be the answer – or maybe not because it’s hard to intercept a pipe so small with precision over a mile deep in the water.  Alarmingly, no one knows with any certainty how this story will end, and the multiple failures of safety and emergency systems can’t make anyone feel comfortable about all the other platforms out there.

And now China now has its own, albeit smaller, oil disaster to clean up – complete with economic, human and wildlife casualties and an environmental impact forecast to last for a decade.

Our global climate is warming at an alarming rate because of our disregard as a species for the impact of our actions.  Or maybe it isn’t.  Wait, maybe it is.  The debate continues…

And did you hear that we are running out of fresh water?

Most of the situations above are far beyond the control of most business owners and employees.  There is very little that most can do, for example, about the BP oil disaster except hope that the situation is resolved soon and urge the powers that be to hold those responsible accountable for their actions and inactions.

All-in-all, it can be quite discouraging.  In the end, we can only hope to contribute some positive news in areas that we actually CAN influence.  Individually and as a collective whole, we should do what we can within the scopes of our businesses to improve the energy and environmental impacts within our control.

Back in April, I posted the steps EXAIR has taken to reduce our impact on the environment.  Yesterday, we updated that information and added it to our website.  Since this kind of commitment brings along with it a never-ending quest for improvement, we’ll update our sustainability plan with new information as it becomes available.

Do your part to the degree that you are able within your sphere of influence, and we’ll help you spread the word.

If your business has undertaken these sorts of measures, no matter how big or how small, let us know via e-mail (, Twitter (@exair) or comment on this blog.

We’ll help you let the world know that most businesses ARE trying to be responsible corporate citizens.
