Choices, Choices

This past Sunday was my birthday. I had planned on teaching my 13-year-old son some basics of pitching…but it rained, so instead, he got a lesson in the basics of plumbing, since the toilet in his bathroom needed a new wax ring installed. It actually wasn’t too bad, since I learned something too: I’ve replaced a few toilet seals in my time, but I never knew how easy it was when help was available, especially from a strapping, athletic teenager who’s capable of lifting his half of that awkward, ceramic hulk. When we go to tile that bathroom floor (don’t tell him yet; it’s a surprise…maybe for HIS birthday), this is one task I don’t dread all that much anymore.

You’re probably thinking of a thousand better ways to spend a birthday, and, a thousand times, you would be right. It wasn’t all bad, though: right before we got into the plumbing project, we had lunch with some of our best friends. Since it was my birthday, I got to choose where we went. After making several fast-food suggestions that I KNEW would be unacceptable to my wife, I picked one of her favorite steak joints, and all was well. Medium well, actually…

Speaking of smart decisions, I had the pleasure of helping a new customer with product selection for a cooling application yesterday. There are many, many situations where an EXAIR product can be used for cooling, but it all comes down to two considerations. Is it better to use:

*A small-to-moderate flow of very cold air (like a Vortex Tube), or
*A high volume flow of ambient temperature air?

In this case, they needed to keep a sensitive component in a vision inspection system relatively cool in a very high temperature environment. For that kind of mass heat removal, the obvious answer was an Air Amplifier:  although a Vortex Tube can produce very cold temperatures, when the temperature of the machinery is more than a few hundred degrees, the relative “cool” of room temperature air will do just fine, especially if you can provide a LOT of it.  What (I hope) sells the customer on it is a video we recently became aware of, showing our Adjustable Air Amplifiers being used to cool the exhaust during the testing of the 2014 Corvette’s 450HP V8 engine:

If you have an application requiring a cooling flow of air and aren’t sure which way to go, give me a call. If the Corvette engine video doesn’t convince you, we can even resort to quantitative analysis of your heat load, which is almost as fun. Almost…
