    TRANE NEW RTAC CHILLER TUBE LEAKED

    2 years old new Trane chiller RTAC, now chiller tube have broken and water entered into the entire circuit. I was told by Trane office that the maintenance might be bad. But the maintenance contractor is not ready to take over any responsibility. Now eddy current test is in progress…but as in a client side what a cost imposed by this ….now there have feelings that trane now do not maintain their quality and reputation, what do you think

    Does the chiller have control of the pump, flow proving working properly? What were the eddy current results, what caused the failure?

    Yes, that is one thing that is overlooked by a lot of controls contractors. Whoever has the BMS, usually wants to control the pumps. The chillers should be controlling the pumps. What does it have for a flow switch and is it operational?

    Also, any isolation valves on the chilled water should be controlled by the chiller. I heard of a bundle ruptured by freeze damage due to the isolation valves were controlled by building controls while the pump was controlled by the chiller.

    It sounds early in the "investigation" to be assigning blame for the failure, and accusations that nobody is standing behind their service and/or product.

    What is eddy current showing, tube wall thinning or rupture?

    How did the tube(s) fail, freeze or corrosion?

    This needs to be determined before any corrective actions can be taken and/or blame(responcability) assigned

    Does the chiller control the pump?

    Trane has to be involved pulling and accessing tube. Because there will be a lawsuit. Were talking a whole new machine. Don't be caught up with what if
    you might have to testifie or someone might overhear what you said.

    He is in the middle east, their legal system is way different than ours, there aren't any lawsuits there, if proven that Trane sold them a "lemon" chiller the salesman would be given two choices "death by public stoning or beheading".

    the BMS is in defunct. so there is no interlock with chilled water pump. but the flow switch operation is healthy.there is 2 additional chillers on this same block. this accident open my eyes to install water pressure differential switch as well as interlock with pump on urgent base
