Thanks Bob.. that's good info. It gives me a ballpark as to how much air I
need to move.
Well, I dug out the book for the smaller (5 KW) reject load here at work.
Unfortunately, they don't give the dissipation rating of the four 200 ohm
And I can't see them without taking the bloody cabinet apart.
But, they're moving 450 CFM across them.
And state a maximum exhaust temp or 237 degrees.
Hmmm.... did you know that 5 KW is equal to 17,050 BTU/hr ?
I remember the load at the AM where I used to work had six ceramic resistors
about the size of a paper towel roll.
Forced air cooled.
But I don't remember the rating on those either....
Dang, guess I ain't much help.....
