20 Year Old Cabinet Cooling System Still Working Today

Recently, I had dinner with some family that I hadn’t seen in a quite a while.  As part of catching up and reminiscing about old times, the discussion went to professions and ‘what are you doing now?’  I told my uncle that I was doing Application Engineering for EXAIR Corporation, and he asked about what we do. I responded that we manufacture an extensive array of Intelligent Compressed Air Products, and then gave a few specifics, like Air Knives, Line Vacs, and Cabinet Cooler Systems. Since my uncle had worked in the chemical process and research industry for many years, he was at least familiar with the products I had mentioned.  He then shared stories about the facility he works at, and because I had worked there many years ago in college (driving a forklift), he knew I would appreciate hearing about all the changes in the last quarter decade.  Eventually, the evening came to and end and we went our separate ways.

Very soon after I received a text message with the below photo attached. Sure enough, my uncle had come across an EXAIR Cabinet Cooler System installed in his facility.  Based on the photo, I identified it as a NEMA 12 model, with a cooling capacity of 275 or 550 BTU/hr. When I did an order history search, I confirmed it was a model 4208 (550 BTU/hr) and found it had shipped in August of 1995, and that my uncle’s name was listed as the order contact, since he placed the order.

Small World!

Model 4208, NEMA 12 Cabinet Cooler System, Installed in 1995 – Still Working Today

Speaking of small worlds, the model 4208 and it’s little brother model 4204, are perfect for small cabinet enclosures that have a minor amounts of internal heat generation, such as a power supply, or moderate outside heat transfer.  Capable of producing 550 BTU/hr and 275 BTU/hr of cooling while using just 8 and 4 SCFM of 100 PSIG compressed air, the EXAIR Cabinet Cooler Systems offer a great way to keep cabinets cool and worry free, as evidenced by over 20 years of operation.  Just provide clean air (a simple 5 micron water/dirt filter is recommended) and it will operate worry free for a long time.

EXAIR manufactures Cabinet Cooler Systems from 275 to 5600 BTU/hr, for NEMA 12, NEMA 4 and NEMA 4X enclosures. They are available in Continuous Operation, (2) Types of Thermostat Control, special designs for High Temperature environments, and a Non- Hazardous Purge. Materials of construction include aluminum, stainless steel, and type 316 stainless steel.

To discuss your application and how an EXAIR Cabinet Cooler System would help out, feel free to contact EXAIR and one of our Application Engineers can help you determine the best solution.

Small World

My world has always been surprisingly small. I know; a lot of people say that, but I don’t think many match mine for compactness. I submit for your approval:

I grew up in a small rural community on the outskirts of Cincinnati, Ohio, and joined the Navy right out of school, to see the world and never come back. I ended up on a Trident submarine and got to travel around the Atlantic Ocean quite a bit, but the only ports-of-call that I saw were Groton, CT; King’s Bay, GA; and an occasional liberty stop in Port Canaveral, FL.

During one of those PCAN port calls, we took on a new crew member, and put to sea for seventy-two days of strategic deterrent patrol (aka hiding missiles from the Russians). One night, on the midwatch, we found out The Newbie was from Cincinnati, too. Turns out, he and I had both lived in the same little one-horse town, where his stepmother was a teacher. I gazed at the name sewn above the pocket of his coveralls, and remembered that my fifth grade teacher had later married a man with that same last name.  As we realized that his father’s wife was my all-time favorite grade school teacher, Machinery 2 grew deathly quiet – sailors love a good omen, and chance meetings like this are real harbingers.  She was a wonderful and effective teacher – I credit her with my love for math.  That’s why I get totally juiced when someone wants to know how fast we can cool something down with a Vortex Tube – or a Super Air Knife – or which one’s better for their application.  Or when questions arise about ventilating a space with an Air Amplifier.  And it wasn’t just math – she just flat-out made learning fun.  I suppose that’s the mark of a quality educator, and it seems that some just have it, and some just don’t. 

Fast forward twenty years: I left the Navy in 1991 and, despite some valiant efforts to keep my vow to never return, I had ended up living in Cincinnati, married to the girl I took to my senior prom, settled comfortably in the ‘burbs with our two young sons.  My boys and I were out one crisp fall day in 2009, participating in that great Boy Scout tradition, the door-to-door Popcorn Sale.  As we canvassed the neighborhood, we came to a particular house in a cul-de-sac, where we found out the owner was a recently retired school teacher.  It had been over thirty years since I’d seen her, but some people you just don’t forget.  After meeting her stepson 400 feet deep in the middle of the Atlantic, she’s now my neighbor!  Small world indeed.

Maybe it’s coincidence.  Maybe it’s fate.  Perhaps it’s a little of both.  But I consider it a unique blessing that someone who meant so much to me in my youth is back in my circle.
