Pitchers And Catchers Report Today!

Just so you know, I’m not talking about anyone’s favorite Major League Baseball team; I’m talking about my oldest son’s Knothole team, the Titans. He wants to try his hand (or, rather, arm) at pitching this year, so we’re hitting the tunnel tonight. Since this is their last year of Knothole ball, the coach encouraged anyone who might consider pitching in High School to come out. Personally, after hearing that it was minus 4 degrees this morning on the radio weather report, I’m feeling warmer already, knowing I’ll be in the same room as some guys tossing baseballs here in a few short hours.

This is NOT what the pitching tunnel at our local sports center looks like.

At EXAIR, nothing reminds us that it’s winter (in the Northern Hemisphere, anyway) like the number of calls that we get for our Static Eliminators. There’s nothing like some cold – and dry – air to really exacerbate a problem with static charge. If that’s a current predicament for you, give us a call. Not only do we have a wide range of solutions, you can get a free AC Sensor with your order right now.


I did, however, talk to a customer just yesterday who was looking forward to warmer weather as well. Well, not just looking forward…he was anticipating it, in fact. Last summer, he’d purchased a Cabinet Cooler System that worked out so well, he wanted to outfit a few more electrical enclosures with them. He was concerned, though, that we wouldn’t be able to accurately specify which ones he needed, since it wasn’t hot enough to be a problem right now. I told him that I could help anyway; we just needed some dimensions and air temperatures. If you’re wondering how we do it (like he was), it’s like this. We want to know the following to size up a Cabinet Cooler System properly:

*The dimensions of the enclosure. We need this to calculate the heat transfer surface area.
*The current internal and external air temperatures. The difference in these, regardless of the time of the year, is proportional to the internal heat load: the amount of heat that’s being generated by the components housed in the enclosure. This difference, theoretically, will be roughly the same in January as it is in June.
*The maximum external air temperature. This is the one that lets us figure out the external heat load: the amount of heat attributable to the hottest day of summer.
*Maximum desired internal temperature. You can specify any temperature you want, and we’ll calculate the cooling capacity required, but, just so you know, our published cooling capacities are based on maintaining 95°F (35°C), which provides a good “safety factor” below the maximum of 104°F (40°C) that seems to be popular with manufacturers of electronic components.

In a nutshell, the data we ask for doesn’t rely on anything except the rest of the data. So don’t feel you have to wait on summer to arrive in order to worry about the heat…and what to do about it.  In fact, it might just make you feel warmer on a day like today to think about it!

Soon enough, I’ll be there with the other Titan’s fans, cheering on our boys at the ballpark, and a few (not me, thank you very much) may even complain about the midsummer heat. For now, I’ll take tonight’s brief respite as a reminder that spring is indeed coming.
