    Westinghouse Chiller HELP

    Hey guys I am working on a Westinghouse chiller. This is a package chiller unit. Info is as follows.

    Style 351A967G19
    Serial DH6513
    Type PBK 2150

    Upon arrival the resident maintanence guy told me the last person there has reclaimed one stage and emptied the oil in the compressor. I am just trying to figure out what is the freon charge for the chiller. Both stages if possible. It originally had a leak, and then he reclaimed 30lbs. So I have no idea how much is supposed to be in there. I have called Mcquay and left several voice mails the past week with no response and the last two days have been on hold for 30min each day. Any help would be greatly appreciated. I have found nothing online either.

    Have you read the units info tag?
    UA LU189

    10mm, because it's better than .45acp

    There is nothing on the tag other than the water and freon pressures. The name and model and serial and type that I listed. That is all I can find on it. I am fed up with Mcquay I called again today and left 2 voice mails and was on hold yet again for 45 min this time.

    It is most likely R12 but you could look at the expansion valves check out the power head.
    Arguing with your Boss is like wrestling with a pig in
    mud.
    After a while you realize that while you are getting
    dirty, the pig is actually enjoying it.

    It is not exactly cheating, I prefer to consider it
    creative problem solving.

    I can fix broke but i can't fix stupid !

    I never even thought of that, I was thinking it was R22....

    I got in touch with the manager at McQuay and he told me this unit was a dinosaur....lol. Built in Aug of 1974. Uses R22 and depending on the barrel size it either takes 73lbs or 113lbs of freon per circuit. So now I am on my way back to figure out the barrel size. Its either 18" or 24." Thanks guys!

    1974 ? That was back when the old timers used R12 as a degreaser.

    Good luck.

    With a boiling point of about -22*F R-12 wasn't a very good degreaser. R-11, on the other hand, with a boiling point around room temperature made a great degreaser. Washed many a part with it into the mid 80's.

    Aren't those the chillers that were supposed to last forever and did not need oil changed and so forth for power plants and such?
