    I could see how the 115 would cause concern, but the 50Hz shouldn't be that big of a deal.

    We build a lot of stuff that is in Phoenix, Vegas, etc.

    I would look at:
    1. What is standard for the manufacturer in the size you are buying.
    2. If there is no clear winner from #1 above, pick the cheapest.

    Yes, you can do that.

    If your piping is higher than the chiller it will overflow the chiller's glycol reservoir unless there is something installed to prevent backflow. The larger the header the...

    The elevation of the pipe does not count against your pump head, because the height you go up, you also go down. It does increase the total length of pipe however; if you go up 20' then down 20' that...

    Eric,

    Before I start, one quick thing about a comment in your post:

    "flowing glycol too fast preventing proper heat exchange."

    FYI, this doesn't happen. However it is a very common...

    My favorite answer; "It depends."

    The difference between single reservoir vs. a dual tank hot/cold system has more to do with the pumping system. The tank design is a byproduct of the pump layout...

    You have some good ideas and good suggestions from other posters. Here are some notes:

    1. For 3 PH kVA = V x A *1.73
    2. You are using RLA, the "Rated Load Amps" of the compressor. Especially in a...

    As others had said, it can be beneficial, but minimally so at your size.

    Other ways to deal with balancing the flow-

    "Too much flow" only means you are using too much pumping energy or could be causing erosion to...
