Hi Ken, hibernating in Florida yet?
Got a 572 sq ft basement room, 2 block underground walls, 2 walls common to other basement rooms. Guy has a museum there trying to keep it under 50% RH. Someone put a 90 ppd dehum in the next room and ducted to the museum room but in the steam of summer, humidity creeks to the upper 50s. This poor dehum, not yours, has way too many pipe & ells so likely not moving near enough air to begin with.
He's wondering if he can save this one. Any guesses as to whether 90 ppd is enough? He thought he had a 135 model. There is a way to remove most of the ducting if 90 is big enough to get some air movement.
Thanks for your thoughts!
