> It was company policy to keep coffee excessively hot (180-190 degrees Fahrenheit, vs 140 or so for coffee brewed at home).

The "official" recommendation for keeping coffee that I've seen, eg here[1], has always been around 80-85C, which translates to 176-185F.

Good home brewers, like this[2], will hold the coffee at that temperature.
