York or Multistack which is better?

[statebuyer]

The 50 ton Multistack closed loop water cooled chiller in my building is dead. I have recieved 2 bids one for a 50 ton Multistack and one for a York scroll chiller YCWL 56 ton unit. Please give me your opinion on which one I should buy.
I've read some theads from techs who dislike Multistack because it needs high maintenance (clean water issues), but I have not seen any posts on the maintenance or reliability of the York 50 ton units. The water in this building is hard with high calcium content. The water is softened with rock salt. I'm having the cooling tower rebuilt with a new wet deck. All suggestions are appriciated.

Even though I work for a competitor of York, I would have to say go with the York.
Our office sells Multi-stack too.
What is the possibilty of going with Trane? If that is not an option, York is next, but stay away from the Maint. nightmare which is Multistack.:eek:

Anything but a Multistack.

multistack - and all other brands/models - disposable

where art thou chiller32? we hasten for your return and quick wit.

anybody seen 'im?

i have to go with the York (if those were my only choices :D). i like the concept of the multistink but i find them being pushed by companies that do not have the capability (i.e. knowledge) of working on larger equipment (screw and centrifugal machines) so they sell these things to "compete".

i think that multi units have their place, but i do believe that it is limited.

good luck.

Its hard to stop a Trane .........................

Guys lets not be too hard on multistacks. Isn't most of our jobs to fix and maintain equipment. To me Multistack=job security. But to the op get a york if thats your only other option but a Trane is definitelt the way to go.

I have worked on a lot of Multistacks and find that if you follow the IOM manual and keep the water clean and treated there are no problems. Some people like to save money on water treatment and run mud thru the chiller after a while even a shell and tube heatexchanger will fail with bad water. I have some buildings that have 10 15 yearold MS that get once a year cleanings and thats about it. With a closed tower not even that. So dont be scared of Multistack. Like everything else if treated properly it will run forever. If not it wont.

plate heat-X and a closed tower loop MS are mint ...otherwise your washing the air outside and filtering it with those H-Xs stay with tube and shell condensers if you can..hows about a nice air cooled TRANE scroll or hellical :D

and stick with water cooled. The CGWF was replaced with our chiller this year, using Trane compressors and high efficiency vessels. Buy it thru your Trane Commercial sales office. It is all easy to maintain shell-and-tube, and is as efficient as you can get. www.nappstech.com

CGWF060 is a great way to go and will make my 401K grow.

The CGWF was pulled from Pueblo Jan 9, 2008, however, we make the same line as a private label for Trane using Trane compressors. Your 401 will still grow, and my salary will get paid. It's now an SWCA60 instead of CGWF60. I gave our web site on the original post for Napps Technology. Paul

Really? Is the IOM still in English?

[PMK]

It better be, we're in East Texas, and have been right here since 1957. You need a copy? Seriously, we're a long time design-build industrial contractor - manufacturer who has built items for Trane (and in the past other manufacturers, but now only Trane) for about 15 years.
