    Slim duct? Is that a mini split?

    My first and only experience with a recording studio, and it was a fairly large recording studio, I told the customer to contact a 'sound engineer'. Boy was my boss pissed!

    Vibration was coming through the structural where the RTU was mounted. Boss said all you need to do is install some cork pad. I laughed in his face. I told him he didn't have a clue what he was talking about. He asked how loud it was. I told him you can't hear it, only the electronics can pick it up.

    The customer did end up calling a sound engineer. And the solution was to mount the RTU on these air bag cushions.

    I asked my boss if he would've thought of that. Think he just grumbled, it was so long ago, can't remember for sure. But I was green in the trade, and that was my first employer in the trade, and I wasn't too impressed with how he handled problems. Spent a whole 16 months there, LOL.
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I am really interested in getting this job. Is looks to be very interesting. We will see. The initial response from the project manager sounded promising.

    Wish me luck.
    Well now,an ENGINEER SPEC'ED out the job? then most of any blame(if there is any) is on his/her shoulders. So this is just a "bid & spec" job.But you should still learn a bit about "noise & stuff" for your own knowledge. I've been "a part" of several Sound Recording Studio jobs over the years. I've also did a few Duck(slaughter) Farms,learned some stuff on them jobs also.

    Just put a 5 ton variable capacity in, it will vary up and down with load no problem, and you dont have to worry about it being undersized.

    I worked around a couple of studios several years ago. We put a loop in the flex duct to help with noise, also oversized. they will tell you the frequency of any noises, helps when tracking it down. When we changed any equipment out, we copied the way it was previously done. Ecm fan motors will be a lot of help if noises turn up during commissioning.
