    Re: Big Centrifugal chillers

    In past there was some good names in the centrifugal chillers such as AIRTEMP,WESTING HOUSE and WORTHINGTON, But they are out of business,Now a days
    MC QUAY and CONTINENTAL from states and
    DAIKEN and HITACHI from JAPAN are also making centrifugals how big that you can find from their sites,

    The chiller body looks like York, but the compressor is not the York machines I know. That must be Mitsubishi bit.

    Any comments Guys

    Re: Big Centrifugal chillers

    Hello,

    Art Kuhn made a nice joke...Johnson Control..why do you think they bought York...
    I was asking for capacity above 5 MW, as I can see in the answers, there is probably nobody else than York and Carrier...

    Actually, Trane can go up to 13.8MW.

    Here's a link to the product presentation.

    We have many of these types of unit in the field.

    Re: Big Centrifugal chillers

    Appreciate for the comment Andy.
    Found the missing link.
    Actually someone wanted to know the availability of the impeller and internal mechanism before overhauling.
    Chiller, medieval age, using R11.

    Was working for Trane in 2002.
    Installation and Commissioning of 3 nos CDHG for a bussines distripark.
    No need catalogs.Got the EAGLES to do the flying for any trane jobs.

    Re: Big Centrifugal chillers

    HI,

    Malik55, thank you very much for the infos,
    it is very very interesting. I had the oportunity to work in MHI in Nagasaki, but obviously it not there that these units were built or they would have tell me something about it...
    Trane, it looks like "old design" units , but please tell me if I am wrong.
    They have semi hermeti with R134 a up to 3,5 MW and "new" unit with R 123, I don't get the point to built new units with this refrigerant, ( only good to replace R 11).
    For the Big Chillers, I have seen 30 MW Units ( 2 in Paris) : multistage from York, 24 MW Carrier ( 1 in Paris ) single stage from Carrier.

    Re: Big Centrifugal chillers

    Why do you think the Trane units look old design?

    And open drive?

    I've worked on several centrifugal chillers from Trane, all hermetic and all on R134a!

    Some early models uses 123 but not the ones we've placed a year ago! And the ten new ones we are going place in Holland are all R134a!

    Re: Big Centrifugal chillers

    Thank you all for the answers, do not hesitate to continue to put more infos for me.
    Sorry for the Trane Remark, they have now units with R134, but on the web, I was a little bit surprised to find still some new units with R123.
    I am very impressed by the Mistubishi units, variable diffuser and variable speed drive is definitly a big improvment for the energy saving.

    Re: Big Centrifugal chillers

    Hi,
    I'm new to site so not too sure how to post etc but anyway here goes I need a bit of help.I have a York centrifugal chiller with a sub cooler in the condenser. We have alot of leaks in the sub cooler & at the moment we are retubing same.When we removed the old tubes we noticed that the tubes sit in a type of mesh wire down through the sub cooler & this is exactly where the tubes are leaking. I would like to know if anybody else has come across this problem & if so how did you rectify it. I would also like to know if anybody out there can recommend a good company to retube shell & tube condensors/evaporators in Ireland or the UK.
    Thanks in advance

    I've had good experiences with Coil Master in Hampshire.
    I don't know if they'd be cost effective to do Irish work, but I reckon it's worth having a chat with them.

    No affiliation, etc.

    Question for Malik. Did you ever work on a Chrysler C2 centrif!! 'Cos if you did you know that they were not the best m/c ever built, also Westinghouse is now Mcquay which has been taken over by Daikin, so maybe the build quality will improve

    Don't forget former Sulzer Friotherm in switzerland,now they have called Friotherm AG,the big impeller is 560mm,and speed is about 15000rpm,so you can image how big it is.

    if you are looking for a real big chiller then try Yorks Titan chiller (multistage centrifugal up to 21MW).........performance matters!
