    150 ton trane screw chiller



    Hey guys,
    I have a 150 ton trane screw chiller that has been going off on some oil faults. There are a bunch of ports on the compressors to connect gauges to, however none are labeled and trane is of no help. They will not give up the information, they send me some bull $hit manual tnat tells you nothing. Does anyone have experience with this machine? Its a. Rtac 150
    Thankyou in advance
    Mike

    Hi
    what are these fault codes?
    the chiller should discribe what kind of fault this is?
    low oil flow?loss of oil?
    once you tell us what the nature of these faults are you will get more responses!
    if you mail me i will send you the relevant manual..
    good luck

    Re: 150 ton trane screw chiller

    The original post by miked123 was posted in regards to the machine I am working on.
    The machine is a Trane Rtac-155 with remote evaporator. In the diagnostic history the unit had a code of 198 "low oil flow". However, after starting the machine up, I have yet to have that error duplicate. I have had error codes 6b3 "low evap temp" and error
    Code 8a "evaporator water flow ( high approach temperature )" these codes shut the unit down on three attempts to start. On the fourth attempt the machine came online and continued to run without trouble. I am wondering why at initial start-up this issue was present.

    Hi Johnny
    The plot thickens!
    Maybe you had some initial cavitation or gas pockets which have now cleared?
    Who knows!
    All well that ends well eh!
