    Re: Ac compressor explosion

    Hi Kefah,

    Normally when a compressor blows up it is because someone has tried to put Oxygen inside it, as the Oxygen react with the oil the pressure multiplies and "pop goes the vessel". Not so long ago an engineer here in UK killed himself trying to pressure test a compressor using Oxygen and the compressor exploded.

    But if we on the other hand is not talking about a full explosion, "just" a terminal that flown of the compressor, this might also happen after long periods of excessive compressor shell temperatures.

    These Fusite terminal connectors sometimes "explode " normally due to the terminal wire coming loose and the terminal overheating and causing arcing and a short circuit to occur. Sometimes the glass insulator gets to hot and cracks causing an earth leakage. This may be due to either the internal connections which you gan do nothing about and can happen during the compressors manufacture, or it can be caused by the external wiring becoming loose etc. I have seen these explode due to metallic particles inside a compressor shorting the fusite connector. It may be just a simple bad quality terminal , it happens unfortunately

    Re: Ac compressor explosion

    could be electrical problems?
    Like 2 phase instead of single
    or weak neutral / ground?

    This is caused by an electrical fault possibly a short circuit inside the machine. I have seen similar failures on Maneurop machines where metallic debris has shorted the pins inside the machines shell . Nothing you can do to prevent this type of failure .

    Well, This happen due to electrical fault that leads for the short circuit. But don't worry it is very easy to fix. Buy new compressor and then charge it to the correct pressure.

    Re: Ac compressor explosion

    this unit had a ***** leakage
    from the flare nut
    so i tighten it
    vacumum it
    charge it by weight
    then its worked perfectly for a month
    in the day when the compressors terminal blown up
    the house owner the electric voltage was low
    as i expect it was between 160 and 140 volt)
