oiless compressors..What will they think of next? 1

[imok2]

Turbocor's family of compressors,
the world's first totally oil-free compressors, are specifically designed for the Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) industry. The convergence of aerospace and industrially proven technologies which include magnetic bearings, variable-speed centrifugal compression and digital electronic controls, enable the Turbocor family of compressors to achieve the highest overall efficiencies for middle-market, water-cooled, evaporatively cooled and air-cooled HVACR applications.

Imok2-I don't know where you get this stuff but...
looks impressive. From what I've been hearing some manuf. are looking at "oil-less" operation as a milestone in compressor technology, ceramic bearings are one proposal being worked on, but this is the first solid operational system I have looked at, and it looks real good. Engineering intent/design seems solid. Incorporates floating magnetic bearings which I've used on Carrier absorber (lithium bromide) systems for refrigerant pumps with carbon landing rings-good thinking. It seems that they's taken solid technology, cleaned it up, used current technology (control systems), updated it all and came out with a nice package. I will be contacting them about some projects I have in mind.Hmmmmm... By the way, thanks.

cjw81, I'm always looking for/at new technology and when I find something interesting I like to bring it to everyones attention. I can't help myself...I love this stuff!

Hi there,

Have you heard of the Trane S-Series Earthwise Centravac chillers?, they are oil free and will be available in 2004

The Turbocor has been used by one of the manufacturers I was talking in testing. They have had some catastrophic failures on cold startups. It sounds good on paper and will most likely work in certain aplications.

The Trane Eartwise ciller has had some problems with the ceramic bearings failing. Matter of fact alot of the CVHfs have had tail bearing failures due to EMF generated in the motor and etching the bearings and races. They have hired an engineer to try and correct this problem. The current fix is a brush to ground mounted on the rear bearing support housing to divert the EMF from going through the bearing and putting it through the shaft to ground. This seems to be working, time will tell.
