    Hi Bruno
    Thanks for your kind help!
    50Hz and 60Hz compressor is only different in motor type?

    Re: 60Hz Copeland scroll compressor

    For 50 and 60 Hz you can use the same compressor.
    For example: a ZR90K3E-TFD can run on
    50Hz: 380/420 V +/-10 % (so between 342 and 462 V)
    and on
    60Hz : 460V +/-10% (so between 414V and 506V)

    Best regards.

    My understanding is the same compressor can work at 50 and 60Hz no need to change motor type. Only the capacity is different.Is it right?

    thanks

    Indeed Lc_shi, you're capacity will increase with +/- 20%
    You got my mail?
    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
