York magnetic bearing centrifugal chiller

[Randy S.]

My hat remains off to McQuay for having the cajones to step out with the WMC.

[Randy S.]

But Johnson owns somebody where I work.

Lets see the WMC is 145-400 ton and the WME 400-550 ton the York 210-400 ton still like the McQuay better , oh and whats with the we can service the equipment better and faster than our competitors equipment yea.

The WME runs like nothing I've ever seen, it does not use the Carell controllers, it's able to ramp up to full load fast and if it jerks the LWT down, doesn't overshoot, doesn't seem to care about condenser water temp hot or cold. Very pleasant changes from the WMC.

I was reading that they could run down to 40 Deg. condenser water with tower bypass control configuration sweet.

Technology is a great thing, but with every advance, I see less work for us in the future.

Right wrong or in different somebody still needs to do a PM on that piece of equipment to ensure that it is running at or near design spec. critical or non-critical appilcation JMO.

From what I can gather the larger machine is a Daikin-McQuay
compressor-not Turbocore. There are a few pics of it on McQ's site
It looks quite different indeed.
For now the truly big iron will still rule, but the day is coming.

If mc hasn't bought up the company that makes the drive and motor for it yet, that might be a good investment. I've heard they apply that same mag lev motor to other things, as well.

I wonder if the new modern York unit has a DX-9100 onboard.

i took care of an M compressor (5 stage) with maglev bearings in it at a natural gas liquifaction plant. ran great but the allen-bradley plc needed a lot of work to get it to start. once it was up and running, awesome!! everyone is afraid of losing work with these things, well, just think if you lose control power, the maching has to coast down on something other than a magnetic field....hence coastdown bearings and those can only sustain so many "landings". the work will always be there, just in different manners. oil less is nice too but the bearings with shield gases always needed attention and filters, and the capacitor banks needed thorough inspections. hopefully the technology will take off, those days of accidently dropping dirty oil filters on a customer's floor and having to clean up do get tiring.

York may not be dead, but their support for the ISN UDC line of products sure is.
