With a Thermostat-Controlled Cabinet Cooler System, EXAIR uses a thermostat and solenoid valve to control the temperature inside an electrical panel. They help to reduce the compressed air usage during cooler temperatures or off-peak hours. Here is a video to demonstrate how to wire the thermostat and solenoid valve to a power source.
I recently had the pleasure of working with a customer in UAE that manufactures tobacco products. They were duplicating an existing line due to an increase in demand and needed another Cabinet Cooler. The previous unit, HT4325-24VDC, had been installed approximately 20 years ago and was still functioning without any issues. This was long before he had started working with the company and they were unable to locate any order history with EXAIR to determine the appropriate model size to order.
They installed the cooler and auto-drain filter that comes with the kit. The only maintenance they’ve had to complete for the system is periodically changing the filter element. The Cabinet Cooler has no moving parts to wear out and requires little to no maintenance so long as it is supplied with clean, dry compressed air.
EXAIR’s UL Listed, CE Compliant Cabinet Coolers are available with Nema 12 (IP54) or Nema 4/4X (IP66) ratings. They’re capable of delivering 275 Btu/hr – 5,600 Btu/hr of cooling capacity and can be thermostatically controlled to reduce compressed air consumption. The rugged nature of EXAIR’s Cabinet Coolers makes them an ideal solution for dirty industrial environments. No longer will you experience shutdowns or downtime due to an overheated cabinet, maintenance required for A/C units, or contamination inside of your enclosure. By purging the cabinet with cool, clean air the EXAIR Cabinet Cooler keeps your cabinet cool while also preventing any dirt, dust, or debris from the ambient environment from wreaking havoc on your sensitive electronics.
The thermostatically controlled systems are pre-set to 95°F, but can easily be adjusted. Check out the video below for a brief instruction of how to adjust the thermostat if you require a different temperature inside the cabinet.
If you have control panels that are shutting down to excess heat, give us a call. With our Cabinet Cooler Sizing Guide, we’ll just need a few quick measurements and we can easily size the appropriate system for your needs.
Recently, I was working with a customer looking for a Premium Reversible Drum Vac and wanted it shipped to the Northwest Territories of Canada – which we could do! It got me to thinking, what are the farthest US state and territory locations EXAIR has shipped to in the North, South, West and East directions. I ‘scoured’ the records and came up with these.
Furthest North- We have shipped to Prudhoe Bay, Alaska. Most recently, believe it or not, we shipped a NEMA 4X Cabinet Cooler to an Oil and Natural Gas Exploration Company. Goes to show that even the coldest environments still have the need to provide cool, clean, dry air to cool and protect electronics in electrical enclosures.
Furthest South – We have shipped to the US Territory of Puerto Rico, city of Santa Isabel. An Aerospace company needed a strong, laminar blast of air and utilized a 6″ Stainless Steel Air Knife. An Air Knife offers a quiet, efficient way to clean, dry or cool parts, webs, or conveyors.
Furthest West- We have shipped to the US Territory of Guam. The local University ordered a model 1111-4 Super Air Nozzle Cluster, for a good strong blast of air flow for a cleaning operation. The model 1111-4 delivers 3.2 lbs of force, at just 82 dBA of sound. A safe and efficient nozzle for blowoff operations.
Furthest East- We have shipped to Eastport, Maine. The customer in Eastport ordered a Line Vac and a section of Conveyance Hose. The Line Vac is a great tool for conveying large volumes of material over long distances, through a standard hose or tube. The compact design features large throat diameters for maximum throughput capability.
It was interesting to look back and see all the places that EXAIR has shipped. We have customers from all over the globe. If you are outside the of 50 US States and Canada, we have a dedicated team of International Application Engineers that will work with you to select the best EXAIR product for your process and application, and direct you to your local International Distributor.

So it was 19°F (-7°C) when I walked outside this morning. The layer of ice on my windshield was thin, but particularly stubborn, and I muttered under my breath. I have no business complaining about the cold…see, I moved to Ohio (on purpose) from Florida, in 1991. In November, to be exact. I still remember where I surrendered my “complain-about-the-cold” card:
Why am I writing a blog about solutions to heat problems when, even though I do have a really nice pair of gloves, my fingers still aren’t even really thawed from ice removal duty this morning? Well, I’ve got three reasons:
1. Outside temperature doesn’t necessarily have any bearing at all on the temperature inside. Sure; there’s a reason we call July and August “Cabinet Cooler Season” – summer heat will do a number on sensitive electronic & control panels in spaces with no climate controls, but the problem goes away as winter approaches. In fact, there’s even such as thing as a cabinet HEATER, if the equipment in question is exposed to the elements. Sometimes, though, heat is an issue year ’round…think blast furnaces, boiler rooms, foundries, chemical plants. If your process generates heat, it’ll affect a control panel in the dead of winter just the same as on the dog days of summer. We can quickly and easily specify the right Cabinet Cooler System for you with just a few key pieces of data…here’s a link to our Cabinet Cooler Sizing Guide if you want to find out.
2. It’s not winter all over the world. Here in the Midwest United States, I full well realize we’re just gearing up for windshield scraping, snow shoveling, slipping-on-the-ice (some people call it skating and do it intentionally) season. But right now, our friends in the Southern Hemisphere are getting ready for heat waves, sunscreen, and (hopefully) air conditioning. So, in essence, they’re moving towards what we call “Cabinet Cooler Season.”
3. Our Cabinet Cooler Systems are so great, the 316SS Cabinet Cooler Systems with Electronic Temperature Control are actually up for Plant Engineering’s Product of the Year Award. Because of their 316SS construction, they’re optimally suited for installation in harsh or demanding locations. The Electronic Temperature Control offers continuous indication of internal temperature, and the ability to change the thermostat setpoint with the push of a button. If you’re a current user, and you agree that they’re great, we’d appreciate your vote. If not, I’m reluctant to encourage you to vote for it, but I suppose I can’t stop you from taking my word for it…
If you’d like to talk about protecting sensitive electronics from the heat, or from the environment, or both, I’d love to hear from you…give me a call.
On first glance, the enclosure shown above looks to be fairly large for use with an EXAIR Cabinet Cooler. Our individual Cabinet Coolers have a maximum cooling capacity of 2,800 BTU/hr. (~820W), but we do provide dual Cabinet Cooler systems with capacities up to 5,600 BTU/hr. (~1642W). So, although there are heat loads which are too large for use with an EXAIR Cabinet Cooler, we always perform heat load calculations for any potential application because until you run the numbers, you don’t really know.
In this case, however, the customer already knew the required cooling capacity (~3,000 BTU/hr. or 880W) thanks to an existing refrigerant based system already installed (see arrows above). This existing system was doing a great job of keeping the enclosure cool when it was working properly, but it was also prone to maintenance and breakdowns. The facility maintenance technicians had replaced filters as required on their preventative maintenance programs, but the A/C unit still required replacement multiple times. This would lead the maintenance team to open all the doors of the enclosure in an effort to remove heat, but this allowed dust and dirt to enter the cabinet and compromise the electronics inside.
Eventually, the maintenance, required repair, and exposure of sensitive electronics led this customer to search for an alternative solution, and they found the EXAIR Cabinet Cooler. Once we determined the required cooling capacity and a suitable unit (model 4750 NEMA 4 Dual Cabinet Cooler System with 3,400 BTU/hr. (~1,000W) of cooling power), the discussion turned to installation and maintenance and we had a conversation something like this:
Customer: How much time do we need to hook up the Cabinet Cooler?
EXAIR: Well, you don’t have to. You just install the thermostat and the system does the rest. It’ll maintain whatever temperature setpoint you chose and comes preset to 95°F (35°C).
Customer: What is the lead time?
EXAIR: They’re in stock and ship same day.
After working through the application and questions from the customer, we were able to provide a sustainable, readily available solution that was a marked improvement from the maintenance prone refrigerant based system. Our Cabinet Cooler allows for easy installation, no maintenance, and years of trouble-free operation. If you have an overheating enclosure contact an EXAIR Application Engineer. We’ll be happy to help you find a suitable solution.
A customer contacted me recently looking to duplicate a setup of EXAIR Cabinet Coolers that they had installed a few years ago. They were tucked away in the corner of the warehouse up near the ceiling. Their maintenance guy had recently retired and no one knew what to purchase. They placed a quick call to EXAIR, after speaking to him and having him snap a photo of the setup, we were able to discern that he had an HT4370 High Temperature Dual Cabinet Cooler System.
They were really under the gun as a similar cabinet elsewhere in the facility was malfunctioning, forcing them to shut down production and open up the cabinet to allow it to cool down periodically. Not only were they losing production time, but exposing the cabinet to the dirty conditions present in most manufacturing facilities can pose additional risks. Lucky for them, we were able to quickly identify the Cabinet Cooler system and get one on order the same day. With same day shipment for stock items on orders received by 3:00 pm EST, they were able to get another one in their hands the following day.
The cool air from the Cabinet Cooler also maintains a positive pressure inside of the enclosure, keeping the dirty air from the environment from wreaking havoc inside. The Cabinet Cooler installs quickly through a standard electrical knockout. The kit includes everything you need to get up and running: the Cabinet Cooler, solenoid valve (available in 110 VAC, 240 VAC, or 24 VDC), Auto-Drain Filter w/ mounting bracket, cold air distribution kit, and a mechanical thermostat pre-set to 95°F. For applications that do not have space for mounting at the top of the cabinet, we also have a Side Mount Kit available.
EXAIR’s High Temperature Dual Cabinet Coolers are available for applications where the ambient conditions are 125°F-200°F. With cooling capacities of up to 5,600 Btu/hr, these Cabinet Coolers will operate virtually maintenance free when supplied with clean, dry air. Not sure which system is right for you?

Solving customer problems by shipping product the same day is a common occurrence at EXAIR. Here is another example.
As companies grow and add more personnel, the details of projects and solutions can get lost if not recorded well. Newer employees may not have knowledge of solution specifics, and unknown details can be hard to discover, especially in larger organizations. An example of this happened recently when one of our customers contacted me about the Cabinet Cooler shown in the image above.
The NEMA 12 Cabinet Cooler was working flawlessly and had been for some time. As temperatures rose, however, other machines in this facility began to experience overheating conditions leading to machine downtime, decreased throughput, and increased stress on operations personnel.
Figuring they’d found the right place, they reached out to me via email and shared their story. And, what they ultimately needed from me was help identifying which Cabinet Coolers they had on hand to mimic the solution in other, identical machines.
Thankfully they provided the image above, which shows a label near the compressed air inlet designating the compressed air consumption (at 100 PSIG). (See below)
Based on this label and the dimensions of the Cabinet Cooler, I was able to identify this as our model 4025 NEMA 12 Cabinet Cooler, which is part of the larger, complete system model 4325. After providing the model number, price, and availability, this customer was able to order the needed Cabinet Coolers which were shipped the same day.
