I have a small Liebert mini mate. We had a leak in it we put dye in to find leak. System had burned out after dye was put in. There was a coating on every piece of the high side components. Compressor, piping, txv and plate condenser had to be changed. my question is did the dye cause the burnout? (create an acid enviroment) I have seen burn outs, but not to this extent. The refrigerant is 407C,poe oil. The smell was horrific.
