More Than One Way To Stay Cool

Camping season begins (for me, anyway) this weekend. Our Cub Scout Pack Spring Campout is this Friday night. This is a mere warmup act for our 3rd and 4th Grade boys, who will then be going to Webelos Outdoor Weekend, at Dan Beard Council’s Camp Friedlander, the following weekend. My best friend Andrew and I will be camping with our sons next month, for our seventh annual Father’s Day weekend.

I would describe my camping ideology as “moderate.” I’m a tent-camper who laughs at people with RV’s equipped with air conditioning and satellite dishes. I do, however, generally stick to State Park campgrounds, and I’m not ashamed of paying a buck or two extra to get a site with an electrical outlet (yes, for my air mattress pump) that’s close to the shower house.

As deep as my disdain for refrigerant-based air conditioning at the campground may be, I must admit that I find it difficult to sleep if it’s too hot. This used to mean I didn’t really like to camp between the Fourth of July and Labor Day, but, a couple of years ago, I happened upon a solution that didn’t involve buying a Winnebago: Turns out, if you fill a cooler full of ice, open the top and blow a fan across it, you can achieve a fair degree of cooling inside the relatively small confines of a tent. So, for a couple of weeks before any mid-to-late-summer campout, I recycle some milk jugs, fill them with water and freeze them. Then, I put them in my “spare” cooler, load up a small box fan (another reason I prefer sites with electric hookup), and I’ve got an air conditioned tent.

Now, I’m not knocking refrigerant-base A/C…I’ve got it at the house, and it’s AWESOME. There are situations, though, where other methods prevail, and I’m not just talking about tent camping.

Electrical enclosures that contain sensitive electronic devices often require a means of cooling those devices. With lower heat loads in mild environments, a vent fan may be all that you need. Higher heat loads will need more cooling than you can get from a flow of ambient air, though. Refrigerant panel coolers are certainly an option, but installation and maintenance can be costly, and they’re prone to failure in dirty industrial environments when dust & dirt can clog the filter.

Conversely, EXAIR Cabinet Cooler Systems offer the following benefits:

*Easy to install: They mount in minutes through an electrical knockout, and are powered solely by compressed air.

*Extremely dependable: There are no moving parts, and, when supplied with clean air (from the Automatic Drain Filter Separator that’s included), will run indefinitely, maintenance free. If high ambient temperatures are a concern, we offer High Temperature units, good in areas up to 200F (93C).

*Clean, cool, and dry: Even if your enclosure is located in an aggressive environment like a chemical plant or foundry, a properly installed EXAIR Cabinet Cooler System will ensure that the only thing the internals of your cabinet are exposed to is clean, cool, dry air.

*Efficient and practical: When equipped with Thermostat Control, they’ll conserve your compressed air supply by only running when necessary to maintain a factory preset temperature of 95F (35C). The thermostat is easy to reset, if you desire a different temperature.

*Prevents contamination: While in operation, an EXAIR Cabinet Cooler will maintain a slight, 1-2 psig, pressure inside the enclosure. We also offer a Non-Hazardous Purge option for our Thermostat Controlled units, which will pass 1 SCFM through the cooler when the solenoid valve is closed.

If you have an electrical enclosure that needs easy, efficient, dependable cooling, let us know – we can help.  You can also send us a request for sizing help directly from the Cabinet Cooler Sizing Guide on our website…with a few key pieces of data, we can accurately and quickly determine the correct model for your application.

Stay cool,
