View Full Version : Bitzer OS85 series gasket problem

03-05-2013, 03:40 AM
Have a problem with the gasket at oil inlet from the oil separator blowing out and loosing oil and refrigerant. This is the second time since new last spring. Is there a known problem with their gaskets. One machine blew the gasket out today and another compressor has a gasket that looks like it is about to go. This machine was started up after sitting since november outside, not in a building. There are 4 identical compressors. Could sitting outside all winter have a negative effect on gaskets? Weather was around 13deg C when started. Oil heaters work, new oil filters installed and new oil. Ideas much appreciated.

Carlos, gasket is item 561, part number is 372 359 02. found the problem was the start up mechanic cut his own gasket out of some sort of plastic gasket material, replaced the gasket with one from bitzer problem solved
