[tig] Room temperatures

You should be looking to keep your machine room temperatures in the
60s Fahrenheit. I have an (American) air conditioning calculation
spreadsheet I can send you if you need it, that converts power draw
into BTU/hr then into air conditioning tonnage to cool it. Seems to
have worked for me here in California.
I seem to remember a statistic from somewhere that each 10 degree F
cooling of the equipment would result in roughly doubling of mean
time between failures. So a room at 90F would fail about 8 times more
frequently than one at 60F. This is an old rule of thumb, though, and
modern, densely packed equipment may be much more prone to heat death.
Humidity, I'm a bit more hazy about (no pun intended). I seem to
remember that about 40% RH worked for us well at Editel. Just right
to avoid static problems with the film.
Offline on this if you would like.
