    Question

    I've been hearing alot about this new magnetic bearing compressor being used in chillers. Since it uses magnetic bearings, are there any special considerations in case there was a loss of electrical power?

    I've been reading alot about these compressors and the technology is amazing. They use capacitors to clean up and regulate voltage so on shutdown or power loss the motor actually becomes a generator to keep the capacitors backcharged and the bearings aligned. There was a good article in the January issue of HPAC Engineering you may want to read.

    Hmm

    I understand the back up of power for spindown in a power outage.

    The real issue is perhaps a electronics failure that lets it skid in, OUCH. I know it will never happen, right?

    Just something to consider.

    I've seen a demo on this compressor. It is amazing. These compressors require NO OIL. You can buy this compressor and retrofit it into an existing machine.

    Trane is talking to turbocor and is considering buying them out.

    Trane is not in a financial position to buy anybody right now....also the technology has not been developed for all of the air cooled platforms necesary to make this product or company attractive for a buy-out. Trane is developing ceramic bearing "oil free " compressors.

    yea what he said

    not to mention they have a McQuay with this comp they showed at the 2003 ASHRE show (water cooled) And Mcquay already has some in the field. I got a felling mcQuay might already have some type of agreement.

    Talking

    Well perhaps Trane could just buy McQuay, what an idea.

    Would the FTC let them?
