    compressor paint bubbling

    Anybody have an idea why the paint would be bubbling on the heads of Carlyle 06d compressor on a Liebert? hp 225 suction pressure 60, 10 degrees subcooling, 12 degrees sh (maybe a little low), 172 degree discharge pipe temp. water cooled. Thanks

    How old is compressor? SH is a little low but sounds like the powdercoat didn't adhere properly and under constant heat load (172F) is causing the bubbling. How bad is the bubbling?

    Is the bubbling only on the heads? What does the air ambient look like? Could be a vinegar or acidic environment.

    Is it only on one head?
    Shoot the heads with your ir gun is there a head that is much hotter than the others?

    Is it the original or a rebuilt?
    Not all rebuilders give as much attention to prepping for the repaint as others.
    None are as good as the factory.
    If it is circuit#2 oil drips from #1 could foul the paint on #2.
