Is it time for mil-spec in plants?

Nice article Joe. Quite enlightening. Is the potential solutioin to this mil-spec parts? Certainly ruggedized parts can better withstand high temperature even if they cost a bit more.

I'm confused. In the example shown, there are three (3) dimentions for the panel area (2ftx4ftx1ft), but this should yield a volume (ft3), not ft2, as shown in the example. Assuming a rectangular prism with six (6) sides, there are two sides with 8ft2 each,two with 4ft2 each, and two with 2ft2 each, for a total surface area of 28ft2. Also, which side is the bottom surface that you are ignoring? Did I miss something? Please help.

Panel is 4' tall 2' wide and 1' deep

4*2 = 8 square feet surface area front

4*2 = 8 square feet surface area back

1*4 = 4 square feet surface left side

1*4 = 4 square feet surface lright side

1*2 = 2 square feet surface are top side

TOTAL surface area = 26 square feet

O.K., Thanks, I get it now. The bottom of the panel is one of the small (2ft2) sides. BTW, the superscript for ft2 was dropped during editing of the original article, so the areas are shown as ft instead of ft2.

EXAIR does have high temperature cabinet coolers. They are good for environments of 200 degrees F. They are of stainless steel construction so they are corrosion resistanct as well
