Last week I wrote about the Thermostat Options for Smart Cooling utilizing the EXAIR Cabinet Cooler Systems. You can see read that blog post here. Today we will touch base on the Side Mount Kits as an option to expand the flexibility for the installation and operation.
Sometimes there isn’t room above an electrical panel to fit the Cabinet Cooler, even though it takes just 5″ to 7.25″ of space above. In these cases, the Side Mount Kit is available to handle any of the Cabinet Cooler sizes and NEMA ratings. EXAIR offers (6) models of Side Mount Kits –
Model 4909 – For NEMA 12 Cabinet Coolers up to 550 BTU.hr (139 Kcal/hr), Aluminum construction
Model 4910 – For NEMA 12 Cabinet Coolers , 650 BTU//hr (165 Kcal/hr) and higher, Aluminum construction
Model 4906 – For NEMA 4 and 4X Cabinet Coolers up to 550 BTU/hr (139 Kcal/hr), Type 303 Stainless Steel
Model 4907 – For NEMA 4 and 4X Cabinet Coolers, 650 BTU/hr (165 Kcal/hr) and higher, Type 303 Stainless Steel
Model 4906-316 – For NEMA 4 and 4X Cabinet Coolers up to 550 BTU/hr (139 Kcal/hr), Type 316 Stainless Steel
Model 4907-316 – For NEMA 4 and 4X Cabinet Coolers, 650 BTU/hr (165 Kcal/hr) and higher, Type 316 Stainless Steel
The NEMA 4 and 4X Cabinet Coolers must be mounted vertically for the unit to properly resist the ingress of liquids and maintain the integrity of the cabinet NEMA rating.
The Side Mount Kits install into a standard electrical knockout (1-1/2 NPS) for easy installation.
If you have any questions about the Side Mount Kits, Cabinet Coolers and/or Thermostat Options or any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
The IP Code, otherwise known as ‘Ingress Protection’, ratings are defined in the international standard EN 60529 (or European IEC 60529.) Similar to NEMA ratings by the National Electrical Manufacturers Association, the IP ratings are used define the level of sealing effectiveness of enclosures against penetration from foreign matter and water/moisture. The ratings for an enclosure are determined by actual testing.
The IP number is composed of the letters ‘IP’, two numbers and possibly one or two letters. The first number refers to the protection level against solids, and the second number to the liquid protection level. The higher the number, the greater the protection level. The optional letter codes relate to protection of persons against access to hazards within the cabinet, and any other special notice.
Below tables show the possible protection ratings and the description-
Example – IP54 – IP – Code Letters, 1st Numeral is 5, 2nd Numeral is 4
An enclosure with an IP rating of this designation, IP54 –
5 – Equipment within enclosure is protected from ingress dust of a limited quantity, such that no interference of performance is caused
4 – Equipment within enclosure should have no harmful effects due to water splashed against the enclosure from any angle
Here at EXAIR we work with IP ratings everyday. The Cabinet Cooler System line of products are made to keep electrical enclosures cool inside, while maintaining the integrity of the enclosure IP Code rating.

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.

Industrial facilities incorporate a variety of processes and procedures to meet customer demands. The ability to convert incoming resources into the desired output hinges upon proper up-time inside of the facility. Whether producing raw materials, performing value-adding services, or manufacturing consumer goods, downtime and failed systems inside of an industrial facility mean lost throughput, lost profit, and increased cost.
As temperatures begin to rise across the US, heat related equipment failures become more prevalent. Industrial facilities need a way to alleviate the problems caused by these increased temperatures and to mitigate the risk of failing electrical devices due to heat.
EXAIR Cabinet Coolers provide this solution using nothing but compressed air.
EXAIR Cabinet Coolers convert a source of compressed air into a very cold stream of air, capable of cooling a sealed enclosure. They are mounted directly to the enclosure, feeding in air as low as 18°F (-8°C) to bring the internal temperature of the cabinet down to acceptable levels. While the cold air generated by the Cabinet Cooler is fed into the enclosure, hot air is simultaneously removed, maintaining relative humidity inside the enclosure at 45%.
Rated for use in NEMA 12 (IP54), NEMA 4, and NEMA 4X (IP66) environments, EXAIR Cabinet Coolers are available in aluminum, 303 stainless steel, and 316 stainless steel. No matter the material of construction, EXAIR Cabinet Coolers can provide 275 – 5,600 BTU/hr. of cooling capacity in industrial applications with ambient temperatures up to 125°F (52°C). For hotter environments up to 200°F (93°C), High Temperature Cabinet Coolers are available.
In extremely dirty environments, Non-Hazardous Purge systems provide a continuous stream of air (1 CFM) into the enclosure, maintaining a positive pressure and preventing any dust intrusion.
Each system type and material are available to ship from stock*, allowing fast delivery to your facility and quickly solving an overheating condition of your devices.
Fans and traditional air conditioners can effectively remove heat, but they provide no separation between the sensitive components inside of an enclosure and the dirty industrial environment outside. Simply installing a fan or AC unit can allow dust, oil, and other ambient contaminants into the enclosure, leading the failure of the expensive equipment inside. And, these solutions degrade over a finite lifespan (the Cabinet Cooler does not), they require routine maintenance (the Cabinet Cooler does not), and they need more time to install (Cabinet Cooler installation is fast and simple). Curious how easy it is to install an EXAIR Cabinet Cooler? Check out this video and see just how easy it really is.
For those applications without enough spacing to mount a Cabinet Cooler on top of the enclosure, Side Mount Kits are available. These kits are also available from stock and are just as easy to install:
All EXAIR Cabinet Coolers are available with thermostat controls to regulate internal cabinet temperatures and compressed air consumption. EXAIR thermostats feature a bimetallic contact strip to open and close the electrical circuit in response to air temperatures. These thermostats quickly respond to changes in air temperature and are specifically suited for their intended use. Preset for 95°F (35°C), a suitable temperature for most electronic devices, these thermostats are fully adjustable for specific application needs.
In the event a more sophisticated thermostat control is needed, Electronic Temperature Control units can be implemented. These standalone units utilize a thermocouple to determine internal cabinet temperatures which display onto a digital readout. Push-button controls on the digital readout board allow for easy modification of the internal cabinet temperature set-point. When the desired internal temperature is reached, the Cabinet Cooler will turn off automatically.
Is it really that easy? Can a Cabinet Cooler provide real cooling for sensitive devices and last for years without any maintenance? Well, here’s an example:
An automotive radiator manufacturer experienced a problem with an overheated motor drive, causing one of their production lines to come to a stop. The root cause of the failure was a leaking refrigerant-based air conditioner, which failed and allowed water into the enclosure housing the motor controls. When the water entered the enclosure, it shorted the motor drive and caused the production line stoppage. The new drive cost over $20,000 and a month of down time to purchase, receive, and install.
Following this failure, the customer searched for a more suitable cooling solution and installed an EXAIR model 4330 NEMA 12 2,000 BTU/hr. Cabinet Cooler System. With an included thermostat control, this system provided proper cooling for the application without any need for required maintenance or potential to leak water into the enclosure.
Fast forward six years and this same customer reached out to EXAIR for another application. During the conversation they mentioned the Cabinet Cooler they purchased many years before was still in operation, still providing proper cooling for the enclosure, and that no maintenance had been performed (Cabinet Coolers do not require routine maintenance). Even in the dirty industrial environment of this manufacturing facility, the EXAIR Cabinet Cooler continued to function flawlessly.
When exploring industrial solutions, required routine maintenance is a common concern. The cost of replacement components and time required to perform necessary maintenance weigh heavily on decision makers. Fortunately, EXAIR Cabinet Coolers do not require any maintenance, and with clean, dry compressed air their lifespan can be 20 years or more. There are no moving parts to wear out or routine maintenance services to be performed.
If you’re in need of a suitable cooling solution for an industrial enclosure, consider an EXAIR Cabinet Cooler. They’re smaller than traditional AC units, faster to install, and require little-to-no-maintenance.
