Do you need a proven way to reduce downtime and increase productivity on a variety of operations involving small parts where heat is a problem? EXAIR‘s Mini Cooler produces a stream of 20°F (-7°C) cold air to prevent heat build up and blow away chips and debris.
Especially effective on high speed operations, the Mini Cooler helps to prevent burning, melting, and heat related breakage, and while doing so, at a quiet 76 dBA sound level. Better yet, all done with no moving parts to wear out.
Mini Cooler Cooling a Small Mill Operation
Some popular applications for the Mini Cooler are – small tool cooling, needle cooling, blade cooling, and lens grinding.
There are several advantages to take note of – low cost, increased production rates, better tolerances, and quiet and compact.
The Mini Cooler Systems are available with One or Two Cold Outlets, and also include a 1″ wide Flare Nozzle Tip, and a Manual Drain Air Filter to clean the air, ensuring long, trouble free operation.
Using just 8 SCFM of 100 PSIG compressed air, the Mini Cooler will not tax your compressed air system. Its small size allows it to fit in areas where larger systems could not fit. The powerful magnetic base sticks to any ferrous surface and and provides up to 100 pounds of pull force.
If you have any questions about the Mini Cooler, the Adjustable Spot Cooler, Cold Gun or any EXAIR compressed air product, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
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.

Any realtor will tell you that the three most important factors in selecting a property are location, location, and location. This simply means that houses with similar features – number of bedrooms, yard size, structure, garage (or not,) basement or not,) etc. – can be found in a lot of very different neighborhoods. Whether you want to live somewhere that’s convenient to the highway, close to (or not so close to) work, near your favorite activities, etc., odds are you can find a house that meets your material needs & wants within those geographical confines. Hence, location is your #1 consideration. And your #2 and your #3 as well…my lovely bride is a real estate professional, so I have this on good authority. And, so you know, #4 is price, and #5 is condition.
Electrical and electronics controls professionals will tell you that three of the most important things to protect their equipment from are heat, moisture, and dust. If you’re looking for a durable, reliable, and low cost method for that, we’ve got the solution: the EXAIR Cabinet Cooler System. Selection of the right system comes down to determining your heat load, and…the reason for today’s blog…the LOCATION in which it will be installed.
Let’s say it’s a control panel for one of the machines on a factory production line…indoors & dry. Our NEMA 12 Cabinet Cooler Systems provide protection against dust and oil from entering the enclosure.
NEMA 12 Cabinet Cooler Systems are oil tight, dust tight, and rated for indoor duty. They can also be installed to the wall of an enclosure (instead of the top) with a Side Mount Kit.
If the enclosure is outdoors, or indoors but subject to water spray (like in a wash-down area,) our NEMA 4 Cabinet Cooler Systems are oil tight, dust tight, AND splash resistant. They ensure the inside of the enclosure stays dry through the use of a low pressure relief valve that seals when the cooler is not operating, maintaining NEMA 4 integrity at all times.
EXAIR NEMA Cabinet Cooler Systems provide additional protection to keep the enclosure dry inside.
Our NEMA 4X Cabinet Cooler Systems are made of stainless steel, and are commonly specified for food service area installations, and in corrosive environments. They’re also oil tight, dust tight, and splash resistant. These are also available in Type 316 Stainless Steel construction, for especially harsh conditions, or when this is otherwise specified due to the nature of the installation, such as critical food grade or pharmaceutical areas.
EXAIR NEMA 4X Cabinet Cooler Systems are made of corrosion resistant stainless steel for corrosive environments, and are also available with Side Mount Kits.
Regardless of the NEMA rating called for by the location, all EXAIR Cabinet Cooler Systems are available with a Non-Hazardous Purge option, which provides a slight positive pressure through a low (1 SCFM) air flow when internal temperature is below the thermostat setpoint and the solenoid valve is closed. This provides constant and reliable protection, even if the enclosure is not perfectly sealed, even in especially dirty or dusty environments.
All EXAIR Cabinet Cooler Systems are available with Non Hazardous Purge for constant, reliable protection from environmental contaminants.
High Temperature Cabinet Cooler Systems are also available when ambient temperatures can exceed 125F. These are popular in foundries, glass production facilities, and even non-air conditioned spaces in particularly warm climates.
High Temperature Cabinet Cooler Systems provide reliable heat protection in areas where ambient temperatures reach 125-200F (52-93C)
If you’ve got sensitive, mission-critical electrical or electronic enclosures that need reliable heat protection, EXAIR has the solution you’re looking for. If you know the required cooling capacity for your enclosure, you can select the right system directly from our website. If you’d like help in calculating your heat load, you can use our Cabinet Cooler System Sizing Guide…just fill in the blanks and click “submit” – your request will be forwarded to an Application Engineer for immediate attention. Or, if you’d rather, just give me a call. We calculate heat loads over the phone all the time; it only takes a minute.

Last year I worked with a power company that was having issues with Position Feedback Sensors overheating causing erroneous readings and early failures. The sensors were located above a steam turbine, and the ambient temperatures reached 128°F with spikes to 140-150°F. The customer had called in looking for a way to keep the sensors cool, using minimal compressed air, and in a robust package. After reviewing the details, we recommended the High Temperature Vortex Tube, model HT3210. While using just 10 SCFM of 100 PSIG compressed air, the HT3210 provides 8 SCFM of cold air at a temperature drop of 54°F from the supply air temperature. Bathing the sensor with this cool air keeps prevents it from heating up and has eliminated the bad readings and prevented the early failures.
The customer recently implemented the same fix for another set of sensors.

The High Temperature Vortex Tube is a special Vortex Tube offering from EXAIR that utilizes a brass generator and hi-temp seal for use in ambient temperatures up to 200°F. Simply supply clean, dry compressed air, and get cold air starting at 50-54°F lower than the supply air temperature. With sizes ranging from 2 to 150 SCFM, there is a Vortex Tube that will meet most applications.
