    Yes 25%glycol 75% water and it will never be below 40*. I wanna ditch the propyln glycol and use a chemical agent that will only minimally affect cooling or heat transfer. Any reccomendations on were and what 2 use?

    You don't say what kind of piping you used, copper,steel or pvc.
    An open system will need a biocide to keep slime from forming. A common ingredient for that is glutaraldehyde. You may also need an inhibitor if you used steel pipe.
    Just put clean water in it and see if your numbers improve. If they do you can go to distilled or reverse osmosis water and the chemicals.

    I used pex and insulated it with the copper insulation. I fully understand this isn't my only problem but its a great start. Next will be checking my gpm and pump.

    just to add, in all my chiller's I have under contract, the only ones we run glycol in are Ice Plant chillers. Way different design and process, I just wanted to let you know no glycol, just treatment for algea and a rust inhibitor

    Just get a service company in, you are spinning your wheels and everyone on this site but have not offered any technical info. Has anyone tried to run the equipment without glycol? Are you sure you don't have more than 25% in the system. Been on jobs and guys say oh I only have 30% in the system and I find the system with 50% or more because they do not know basic mathematics.

    i think this site was created to help EVERYONE, and most of your comments have been very helpful and appreciated. I was only asking a simple questions, if this was a proper way to test the btu of a chiller. I am gonna drain the system and run water, a rust inhibitor, and algae. . if i hadn't come on this site i probably would not have figured out i am wasting btu on glycol.THANKS TO EVERYONE WHO OFFERED HELP

    I do not know where you guys all live?

    wher I live and work, we must keep from freezing down til -20 deg F!

    we mostly use polypropylene glycol
    polyethylene glycol is not eco friendly enough!

    ethylene is better because you do not have to add or mix as much!

    anyways????

    propylene has to be about 40% to be good down to -20

    I believe the specific gravity is about 1.032 or so?

    anyhow most guys just mix it 50 50!

    I mix it about 60-40 water to start

    OFCOURSE!!!!!!!!!!

    I just test it with a refractometer anyhow so the original mix does not matter much??


    just curious??

    what area of math are your co-workers so bad at, thatthey can not get that right??

    You don't have enough steel to worry much about a rust inhibitor. Biologicals will take a while to form.
    Put tap water in it and see if your numbers improve. If they do, flush it, add chemicals and distilled water. If not you have saved throwing more money at it, and you have to go another direction anyway.
