Automatic Balancing Valves-ABV 2

[MedicineEng]

Hi everybody and Happy New Year:

For a new expansion project that we are currently working on, a discussion came across the group that for our hotel tower, we should use automatic balancing valves to regulate our guestrooms toilet exhausts.

We are looking into these products Link

On their website it looks pretty straight forward and actually quite effective but we all know how that sometimes doesn't reflect in real life applications.
I confess that I never worked with a system like this before, so I don't have any hands on experience on this.

Is there anybody out there that worked with this? Can you please share your experience or thoughts on this system?

Thanks a lot

A hotel tower is actually a wonderful application for these automatic balancing dampers because the building pressure changes as the seasons change (stack effect) and the CFM required for hotel rooms is typically pretty low (about 30 CFM). If you just have manual balancing dampers then they would get out of balance between the lower and upper floors as the temperatures and wind changes outside.
