Steam tunnel fan experience? 1

[MarauderX]

I didn't readily find any steam tunnel fan threads, so I thought I would ask...
Does anyone have any experience installing/replacing steam tunnel fans?

More specifically, should the size of the fans be based on a volume air change per hour, or by estimated heat loss to the tunnel from the steam piping? Presently we are looking to provide ventilation and air changes per hour, but don't want to have too much air movement. Any experience would be very helpful.

Thanks in advance -
John
