Turbocor is the brand name from Danfoss. They invented the compressor and it is a wonderful design. Daikin McQuay designed a higher mass flow compressor that is used in our chillers over 400 tons. We just released the 700 version a few weeks ago. It containing one centrifugal compressor and one motor with an external refrigerant cooled VFD as standard.
I saw one in action for the 1st time this week, It has been in use for a few years where I just started working, the amazing thing is how quiet it is, and they say they have had no problems, and being it is Key West Florida, I must say it works quite well in our application.
The compressor rotor backup bearings support the Turbocor rotor when power is off. The larger McQuay compressor on the WME chiller has the same support.
How would they control thrust movement on this machine? It would have to match the load properly and be taken care of. It looks like a surge would push the shaft through the end bell ..lol
I did a big presentation on the turbo-core chillers back in college. (I have a B.S. in Engineering). Just a quick question because I've forgotten... Does the compressor rotor assembly rest on the magnetic bearing surface when not in use?
This technology is a great push in the right direction. It's too bad this thing is such at dog whenever you have warmer than 75 degree condenser water though.

We had the main control board plug get hot and loosen up. They held it together with a wood clamp until the new board came in.
McQuay releases this chiller in a 700 ton version June 9, 2011
Same chiller arlam inter inverter communication link error
Bearing orbit arlam please solved the problem?

The chiller performs well above 75F Condenser Water temperature.

No, rotor is de-levitated when not in use
how does a 6 cycle voltage sag affect the controls?
@tohellwithit1 you're right

I am here saying hello
134 has phase out schedule...
magnetic bearings ? Power shutdown should be catastrophic
nicolas0065 nah its got a big capacitor init
723lion More like a capacitor bank. If one of them blow up they can send a cabinet door clear through an 8 inch steel pipe.
crap
