Adjustable Spot Cooler as an Enclosure Cooler……Really???

Yes, is true. Many times when customers contact us about keeping a “cabinet” or “enclosure” cool, the enclosed space is not always your typical electrical or control panel cooling situation. Sometimes, customers have simple boxes or enclosed spaces that are reasonably small and need to be cooled for a variety of reasons.


This next example is one where a customer has a special light used in a paper making application. The light is exposed to high humidity and high heat which are normal constituents in paper making. The customer has had the light fail and the reasons were specifically attributed to the heat and humidity. In looking for a solution to his problem, the customer came across EXAIR and our Vortex Tube product. He researched and became familiar with the virtues of using a Vortex Tube for small cooling applications like this one.

When he contacted me his mind was pointed in the direction of a plain and simple Vortex Tube which is a good start. What I suggested to him though, was to consider using an Adjustable Spot Cooler instead. An Adjustable Spot Cooler is a Vortex Tube; however it is engineered to include heat shielding and sound muffling which make the whole use of a Vortex Tube a much more user friendly experience. Basically, I did not want the customer to try and have to figure out these issues on his own when we had a stock product ready to use right out of the box. All he has to do is to connect the unit to his box to be cooled, connect the compressed air and adjust the output temperature to what he wanted it to be.

You may ask, “Why didn’t he recommend a Cabinet Cooler?” That is a good question. I didn’t recommend a Cabinet Cooler for one good reason. Cabinet Coolers are designed with a target temperature of 95F (35C) in mind. In this case, the customer wanted to maintain close to 65F (18C). This fact fit well with the easy adjustment of the Adjustable Spot Cooler to accommodate the target temperature. Flexibility was a key feature in terms of being able to set the target temperature and have it field adjustable as well.
