EXAIR Cabinet Cooler System Used on Cement Barge

I joined the Navy, right after high school, to get out of Ohio, see the world, and never come back. “My recruiter said” (if you are considering military service, those can be famous last words, just so you know) that I would be a good candidate for Nuclear Power School, so I took the test. As a math & science nerd scholar, I qualified for admission easily.  About halfway through Nuke School, I volunteered for submarines.  My decision was based in no small part on the sea stories of our instructors, the strong reputation of better food, and my deep appreciation for the movie “Operation Petticoat.”

Upon graduation, I was assigned to a new construction Trident submarine.  I did not see the world…I saw the Electric Boat shipyard in Groton, Connecticut, and Naval Submarine Base King’s Bay, Georgia.  Hilarity occasionally ensued, but never in the context of that movie I so adored.  I moved back to Ohio (on purpose) soon after my enlistment was up.  The food WAS good…I can unreservedly vouch for that.

In the new construction environment of the shipyard, I became quite familiar, and developed a deep respect for, the high level of attention paid to the materials and workmanship that a seagoing vessel demanded…not to mention, one with a nuclear reactor on board.  Reliability and durability are obviously key factors.

I had the pleasure recently of assisting an electrical contractor who was looking for a cooling solution for a new Variable Frequency Drive enclosure installation on a cement barge.  The ship’s engineer (a Navy veteran himself) had told the contractor that his priorities were reliability, durability, and dust exclusion.  He couldn’t have made a better case for an EXAIR Cabinet Cooling System.

Based on the specified heat load of the VFD, the size of the enclosure, and its location, a Model 4380 Thermostat Controlled NEMA 12 Cabinet Cooler System, rated at 5,600 Btu/hr, was specified.  This equipment is internal to the ship; had it been exposed to the elements, a NEMA 4X system would have been presented.

Up to 2,800 Btu/hr cooling capacity with a single Cabinet Cooler System (left) or as much as 5,600 Btu/hr with a Dual system (right.)

EXAIR Cabinet Cooler Systems have no moving parts to wear, no electric motor to burn out, and no heat transfer surfaces (like a refrigerant-based unit’s fins & tubes) to foul.  Once it’s properly installed on a sealed enclosure, the internal components never see anything but cold, clean air.

If you have a need to protect an electrical enclosure in aggressive environment, give me a call.  With a wide range of Cabinet Cooler Systems to meet a variety of needs, we’ve got the one you’re looking for, in stock and ready to ship.

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.
