Can An EXAIR Cabinet Cooler Work With My Enclosure?

NEMA 4X Cabinet Dimensions

As I scanned through my emails this morning in search for a Cabinet Cooler Sizing Guide sent to me back in June (some changes were made by the end user and I wanted to reference the original heat load), I noticed the large number of sizing requests typical of summer months.  When I clicked back to my inbox I saw four more Cabinet Cooler sizing requests awaiting me from different corners of the globe.

One that stood out to me was in a particularly hot environment (Approximately 180 degrees Fahrenheit), and needed NEMA 4X protection.  The end user was kind enough to send a sketch of the enclosure they plan to use, and needed to know if an EXAIR NEMA 4X Cabinet Cooler could work for their application.

Fortunately for the end user, our Cabinet Coolers are suitable for many types of enclosures, and we have a staff of Application Engineers on hand to sort through any abnormalities or questions which may arise.  So, we are able to say with certainty that our Cabinet Cooler can work in their application.

Another fortunate feature for this end user is that EXAIR manufactures High Temperature Cabinet Coolers available from stock, and suitable for temperatures up to 200 degrees F.  These high temp systems are perfect for metallurgical plants, use near ovens or furnaces, and for applications with higher than normal compressed air temperature.

If the specifics of your application raise any doubt about integrating an EXAIR Cabinet Cooler, contact an EXAIR Application Engineer.

Air Amplifier Provides Cooling for HOT Parts

Hot Cylinders

The five C’s of EXAIR products are Cooling, Cleaning, Conserving, Conveying, and Coating.  All EXAIR products are suitable for applications in these areas, with varying degree of possibility.  When it comes to cooling, one of the most suitable EXAIR products is the Super Air Amplifier.

An Air Amplifier can increase the volume of ambient air directed over an specific area, effectively decreasing the cooling time needed in an application.  Air Amplifiers cool effectively due to the fundamental principles of convective heat transfer.  In convective heat transfer, cooling capacity can be increased by increasing the temperature differential between the cooling medium and the object to be cooled, or by increasing the flow of the cooling medium.

An Air Amplifier is the best cooling choice when the material to be cooled is at an extremely high temperature.  For example, in the application above, 903°C (1650°F) cylinders need to be cooled to ambient temperature as quickly as possible. Vortex Tubes are another product our customers consider for cooling applications. Vortex Tubes are the best choice when the area to be cooled is small and the temperature differential is not as large. A Vortex Tube based solution will provide very cold air, but at a lower air flow over a small area and they were not the best choice for the application in the image above.

In the same application, a Super Air Amplifier can provide large volumes of ambient air over a large area, effectively cooling the cylinders much more efficiently.  The cooling can be achieved in less time, and with maximum efficiency of compressed air implementation. Air Amplifiers also offer great benefits over electric fans in this rough environment: they can withstand higher temperatures and there are no moving parts to wear or break.

If you have an application in need of efficient cooling, contact an EXAIR Application Engineer to find out if an Air Amplifier will work for you.
